EDISON — A sign warning people that an area of the Edison Boat Basin is currently under environmental remediation and investigation has been posted by the chemical company Akzo Nobel, a firm currently the subject of a lawsuit brought by an environmental group over chemical seepage. The posting of a sign is one of several actions that the Edison Wetlands Association, the aforementioned environmental group, had demanded the company take, because the area about 100 yards upstream remains a popular site for fishing, boating and other recreation. The lawsuit, formally launched early last year, also demands that the company conduct a full cleanup of the site, which the EWA has said plays host to a number of hazardous chemicals, such as benzene, arsenic and 4-chloroaniline. The group has said that the chemicals originated from the Akzo Nobel manufacturing plant and contaminated the area through poor disposal practices. At an attempt to obtain a
preliminary injunction before U.S. District Judge Faith Hochberg last
year, which was ulti- mately denied, representatives of the defendants
said the extent of the environmental damage had been overstated and that
the firms involved are already in the process of working with the New
Jersey Department of Environmental Protection in cleanup efforts, and so
the defendants questioned why legal action was needed.<more>

PRA and Pera announce merger
PRA (Paint Research Association) and Pera are pleased to announce that
they have today merged both organisations following an Extraordinary
General Meeting of PRA Members, held at the Coatings Technology Centre,
Hampton, Middlesex, UK.
This follows a successful year for PRA, which will continue to operate
autonomously but as part of the Pera Innovation Network.
Jonathan Bourne, Managing Director at PRA, said "Merging with Pera will
enable us to consolidate the very positive progress made over the past
three years and to further develop our services in support of the
innovation and growth of PRA member companies".
A key benefit of the merger will be the integrated support that will now
be given to companies pursuing government funding for R&D projects,
whether under EC or national schemes.
John Hill, Chief Executive at Pera, said "The merger is an important step
in the further development of Pera into an international organisation and
with PRA as part of the Pera Innovation Network, we will have an
outstanding competency for industrial materials and nanotechnology

Dow Chemical & Rohm Haas:
Mutually Assured Destruction?
Dow Chemical and Rohm &
Haas faced off by phone before Delaware Judge William B. Chandler III
Monday and Tuesday to discuss Rohm’s breach-of-contract lawsuit concerning
its agreement to be bought for $15.3 billion by Dow Chemical.
missle0128_HS_20090128180757.jpgAssociated Press
Deal Journal has reviewed transcripts from those calls and presents an
exclusive look at the best bits. What emerges can be called Dow Chemical’s
scorched-earth defense, in which the Midland, Mich., chemicals
conglomerate says that completing the acquisition would destroy Dow
Chemical–and Rohm with it, leading to thousands of layoffs. Rohm contends
that Dow Chemical has no legal reason to walk away from their $15.3
billion deal or to stall for more time. We have grouped excerpts from the
transcripts by theme.
Would Dow be bankrupt if the deal goes through?
David Bernick, partner with Kirkland & Ellis, representing Dow Chemical:
“This deal faces a very, very big problem….And the essence of what this
case is about is whether somehow that problem is going to go away if
there’s a forced merger pursuant to the terms that were originally agreed.
Our position is that, fundamentally, it doesn’t make that problem go away.
To get a Court to order it doesn’t make everything all of a sudden
resolve. Indeed, it has precisely the opposite effect, which is what is a
problem of varying disagrees of magnitude for the two different companies
becomes an overwhelming problem for the merged organization, and one that
is now a problem for both entities who have now contributed to the
merger.”<more>

Colourful Q4 likely for paint
companies
KOLKATA: The organised
decorative paints industry, which suffered a setback in the third quarter
of 2008-09 due to economic slowdown, is hoping to
witness some positive growth in February-March 2009. A major reduction in
paint prices, due to a dip in input costs, is expected to emerge as a
major growth driver for the paint companies in the next few months.
Prices of decorative paints have declined by 10-12% in the last three
months and some of the organised paint makers like Shalimar Paints feel
that there may be another round of price reduction by the end of this
month.
“Paint companies have been able to reduce prices owing to a fall in crude
oil prices, one of the key inputs of paints. This will catalyse growth,”
said Abhijit Roy, vice-president (sales & marketing), Berger Paints. <more>

New Silicone based Emulsion
from Dow Corning Improves Paint and Render Performace
Dow Corning
recently introduced Dow Corning® IE-2404 Emulsion, a new chemistry that
improves performance in silicone resin emulsion paints when used as a
co-binder. Formulators of paint and facade renders will achieve
significant benefits using this emulsion, including lower water
absorption, increased permeability to water vapor, improved weatherability,
and reduced dirt pickup.
Water, sun, and industrial pollutants cause paints and facade renders to
prematurely age – detracting from the general aesthetics of the product
and increasing maintenance costs. Dow Corning IE-2404 Emulsion provides
core benefits, such as UV stability, repaintability, uniform appearance,
and damage resistance.
“Coatings made with silicone resin emulsions combine the best of both
worlds when it comes to weatherability and water protection,” said Terry
Chapman, technical service representative for Dow Corning’s building
materials protection group. “These materials simultaneously create a
hydrophobic environment by binding directly with inorganic materials in
the paint, and still allow water vapor and carbon dioxide that would
normally be trapped under the coating to permeate. This is especially
important in water-sensitive substrates, such as masonry, plaster, and
exterior insulation facade systems (EIFS), where unwanted moisture can
damage the material or result in microbial growth.” <more>

By
K.K.Deodhar,
Process: Eco friendly Decorative Wood ,Granite, Marble effect and other
fancy powder coat finishing of Aluminium Profiles, Sheets and other
Galvanized and phosphate metals Introduction and general review of
Thermoset Powder coatings- New trend: Indeed it is needless to mention
that Powder coatings Technology is the fastest growing finishing method
amongst other Surface coatings in this new millennium, which is currently
increasing by 15-20% per annum in India and Asia Pacific rim .Powder
coatings has sustained a long way in the past decade, and this fast track
finishing technology is rapidly capturing new markets with deeper
penetration into wet paint sector.
Market trends and pressure are fast changing the scenario, and is poised
to capture a large slice of the wet paint market, the changes in end user
market has spurred growth , which together has resulted in wide research
and development activity in basic raw materials, and application systems.
These advances have brought about commercialization of innovative powder
products and application methods. The opportunities due to rapid
globalization has driven the technology
to maintain a balance between environment, economic and social aspect.
Many new products have been developed in the western world with commercial
application, many yet to arrive in this region of the globe.
We can look at the advanced technological achievements with a view to
implement them in our industries to take the advantage of realistic
economics in terms of energy saving, material saving and increased
productivity. ,enhanced quality in terms of long term durability of the
product finish, impressive appearance and aesthetics to enhanced display
shelf appeal, and finally contributing to zero emission norms and
regulations of volatile organic content. Thermosetting powder coatings are
based on lower molecular weight solid resins and melt when exposed to
heat. After they flow into a uniform thin layer, however, they chemically
cross-link within themselves or with other reactive components to form a
reaction product of much higher molecular weight. These newly formed
materials are heat stable and, unlike the thermoplastic
products after curing, will not soften back to the liquid phase when
heated. Thermosetting powders are derived from three generic types of
resins: epoxy, polyester and acrylic. From these resin types, several
coating systems are derived. Resins used in thermosetting powders can be
ground into fine particles necessary for spray application and a thin film
finish. Most of the technological advancements in recent years have been
with thermosetting powders.
Advantages of powder coating:
Why powder coat -Speedy production, Environmentally-friendly Economy
,Anti-corrosion
Tough finish Easier-application No Runs No-overspray, Good Wrap-around,
Edges
coverage
Six main reasons why powder coatings are replacing wet paints.
Powder coating was first commercially used since the late 1960’s, although
like most innovative ideas it was slow to start, it has become the fastest
growth area in the painting industry. This has been at the expense of the
wet paint industry.
Six main reasons why powder coatings are replacing wet paints.
1. Speedy Production-Cheaper product price.
Nearly all wet paint systems require more then one coat, but all wet paint
systems take a long time to dry unless baked. Compared to powder coating,
which normally requires one coat only, it can be painted, cured and ready
to pack in twenty minutes on a conveyorised line.The moment it is cool
after having been fully cured in an oven, it is as hard as it will
ever get, and can be wrapped.
2. Environmentally-friendly
It is now important to be seen as environmentally friendly. Powder coating
does not rely on the use of solvents. The powder melts to form the liquid
coating. No volatiles(free of VOC)hence contribute to protection of
environment and eliminate pollution It does not generate odors during the
curing, and can be used on hot areas like domestic
radiators.
3. Economy
On long runs, the powder that is not attracted to the work piece is
collected, sieved and passed through the guns again .During Powder
spray application, over sprayed powder is recycled for reuse unlike liquid
wet paints where 70%goes to waste in atmosphere causing pollution.
One step coating, Less skilled labor needed.
High efficiency (95 %)recycled ,1 Kg Powder = 2.5 Kg Liquid Paint .
4. Anti-corrosion
Wet paints can be diluted with as much as 90% solvents. When these
solvents evaporate they can leave pores in the paint film. These are
weaknesses against moisture permeating through the paint to the surface of
the metal. A powder coating is a solid film, high density polymer network
bonding, offering a more water tight shield. It is for this reason that
one coat used to be considered enough, and that it does not need to be as
thick as a wet paint film giving the same corrosion protection.
5. Tough-finish
The most popular resin used for powder coatings is polyester. This is a
long chain molecule, which is both tough and flexible. Powder coatings are
generally tougher and harder wearing then wet paints.
6. Easier-application
The following shows examples of why powder coating is easier to apply than
liquid paint.
Runs
Runs are rare, as the molten powder is viscous.
No-overspray
Spraying a complicated component using a wet paint on a motorbike frame or
with uprights every 100mm presents problems with overspray. In order to
get a wet paint to flow out and look smooth and shiny, the coating has to
be applied wet, so that the paint droplets flow into each other. This
usually means the gun has to be close to the work piece so that the paint
does not dry in the air on its way to the surface. This produces a dry
rough finish, like sand paper. On a motorbike frame ,as the gun is
concentrated on the nearest tube, the overspray will ruin the tube
previously sprayed.
With powder coating, the whole component is sprayed with powdered paint,
and only once all the painting has been completed, it is then heated to
melt the powder to a liquid. Over spray is then not a problem. The final
finish is a smooth glossy tough coating.
Wrap-around
Again using the motorbike frame or a railing, the advantage of spraying
with electrostatic powder is the wrap around effect. A tube can be sprayed
from one side with an intended film thickness of 50 microns, if the guns
position is stationary the wrap round will coat the other side to an about
30 microns. This makes the spraying considerably easier and enables
a more even coating. The gun is able to cover major intricacies of
Aluminium extrusions excepting very deep recessed area which need special
parameters of application due to Faraday’s cage effect. Edges Because of
wrap round, edges and difficult areas to see are not missed as they can be
with wet spraying.
Orange Peel
The following comments are relevant to aesthetic coatings, not heavy-duty
wet paints. One of the criticisms of powder coating is that it suffers
from excess orange peel. All paints suffer from orange peel effect. This
is partially due to the surface tension of the paint whilst in the liquid
state, its viscosity (the thicker it is the more orange peel,) and how
much is
applied in one coat. (The more applied, the more orange peel.)
Because up to 90 microns of powder can be applied in one coat, compared to
20 microns of cellulose the orange peel effect can be very noticeable. It
can be reduced by the choice of powder manufacture, and by using more
expensive powder with a different chemistry.
Car-industry
The car industry is keen to move to powder because of the listed
advantages, and because all the painting can be completed in three coats.
(Primer, color and lacquer.) A smooth finish comparable to multiple coats
of wet paint is now available with acrylic lacquers, but these are not
compatible with polyesters and are very expensive. New developments to
simulate wet liquid paint characteristics are achieved and the use of
powder coating is already implemented on light commercial vehicles, Car
outer body etc. .
Thermoset Powder coatings are divided into main two categories:
1)Decorative products - Decorative finishes -
Decorative Conventional General use –Epoxy, Polyester-Epoxy
Decorative finishes with enhanced aesthetics and appearance-available in
all chemistries – Epoxy, Polyester-Epoxy Exterior grade Pure
Polyester(TGIC and TGIC free).Common special effects are-Texture
,Structure, Wrinkle, Hammer tone, Metallic, Sorbet, Antique,
Premium special effects are Wood grain, Marble, Granite and other fancy
effects.
2)Functional products - Special Application coatings and systems
i)Powder coatings for Specific end use applications for Steel, MDF wood,
Plastics, Pipe, Rebar ,Electrical insulation etc.
ii)Powder coatings for performance oriented end use applications in
Architectural Aluminium profiles, facades, doors etc. which include long
life durability-Super durable Polyester, PVDF, Emission free Polyurethane
powder and liquid coatings.
In this article we highlight the main use of REALWOOD -Wood effect Powder
on powder coatings process for Architectural Aluminium industry, which is
poised for a rapid expansion and development in the coming years in India
due very high volume requirements on account of Residential, commercial
Building complexes, Large
infrastructure projects ,Super and HyperMalls.
Demand for innovative and value added products in Architectural use are
supplemented by Premium quality in terms of aesthetics and protection from
atmospheric agents.
As architects and designers look for more varied and exciting finishes,
they are realizing the benefits that powder coatings can provide them with
as a high-performance, environmentally responsible method of enhancing the
beauty and durability of the buildings they design. In particular, the
choice offered for coating aluminum profiles and cladding grows with new
innovations in application and finishes, including decorative marbled and
wood effects, providing architects and designers with quality powder
coatings technology and unique finishes to differentiate and protect their
designs.
Powder coatings for Architectural products have been designed over many
years to satisfy the unique requirements of the worldwide building
products industry with all the environmental excellence of the powder
coating process. Available to architects and applicators globally, the
broad range of products in the architectural portfolio, designed to
balance economics and performance, exhibit a range of outdoor
weatherability and mechanical properties that can allow a user to meet the
various demands of architectural governing bodies. These include the
American Architectural Manufacturers Association (AAMA) specifications for
organic coatings on aluminum extrusions and panels as well as the strict
quality requirements of European architectural governing bodies – GSB,
QUALICOAT (class 1 and 2) and British Standard (BS
6496 and EN12206-1).
Premium Value added aesthetic powder coating finishes:Wood effect and
Marble finishes are obtained by two type of processes
1.REALWOOD Powder on Powder coating system and technology
2.Dye Sublimation transfer process
Wood and Marble Effects. New finishing processes provide wood-grain and
marble effects to aluminum, often used on indoor and outdoor architectural
products such as furniture, windows, doors, vents, handles, and fixtures.
1.Real wood patented Powder on Powder process :Is the latest technology to
imitate wood and other effects on powder coated Aluminium and steel. It is
very popular in Europe and Middle east, and gaining acceptance world wide.
REAL WOOD Powder-on-powder process offer a consistent coating of similar
chemistries whereas in sublimation process, the ink layer is different
chemistry than the base coat, which has different performance
characteristics. After the curing
process, the second patterned layer of powder coating penetrates,
polymerize into the first one, creating a compact and uniform layer which
imitates the look and feel of wood and thus the name of the patented
technology, the most important technical advantage(including other process
and cost advantages)of the REALWOOD system versus the sublimation system
is the absence of ink in the pattern transfer process. Aluminium profiles
coated using the REALWOOD process can only be approved with powders that
have been Qualicoat certified and provide the performance characteristics
for exterior atmospheric exposure in all types of weather conditions,
strongly advised in tropical climatic conditions of high temperature and
high humidity like in India.
2.Dye Sublimation. The process of transferring three-dimensional images
onto parts and products, known as dye sublimation, has been successfully
applied to powder coated products. Now high-resolution images, designs,
and wood-grain looks can be transferred to a variety of powder coated
products made of steel, aluminum, glass, and medium density fiberboard.
Bottles, multi-function knives, bicycle frames, and writing utensils are
among the products benefiting
from this vibrant new look. It has been mainly used for interior
applications.
Premium Real Wood effect Powder on Powder coating of Aluminium
Architectural profiles:
Process: Eco friendly Decorative Wood , Marble effect and other fancy
powder coat finishing of Aluminium Profiles, Sheets and other Galvanized
metals.
REALWOOD Patented Finishing System:
Real Wood effect finishing has seen growth in popularity over the years,
particularly in Europe, as a real alternative to typical architectural
materials such as wood, marble . The powder coated finish provides the
high weathering performance of aluminum coupled with the decorative
appearance of Real Wood. Decorative wood effects can be achieved in one of
two ways:
REALWOOD Powder on Powder system require special grade of thermoset powder
coating material and special system of application.
Real Wood Mainly developed for Exterior atmospheric exposure performance
and widely used to coat Aluminium Extrusions which are used in fabrication
of Windows ,Doors, Facades etc.
Real Wood process
The Real wood process is also known as the “powder- on-powder coating
system” as it is a two stage process using two applications of powder
coatings. This patented process to obtain a wood effect finishing on
aluminum profiles can be achieved by using Qualicoat-approved, TGIC-free,
TGIC polyester powders:
· Substrate pretreatment; normal standard for Aluminium
· first layer powder base coat application (70 to 80 μm)with partial
baking
· second layer powder application—a rapid coating and fixing of wood grain
patterned layer with patented REALWOOD system and technology. and final
curing process (180º to 200°C for 20 minutes).
After the final curing process, the wood grain patterned second layer of
powder paint has penetrated and polymerized into the first one, creating a
compact and uniform layer of at least 70 μm thick or more. The final
result is a powder-on-powder process and the surface appears similar to
wood in look and feel with high performance outdoor weatherability
characteristics.
Characteristics of treated materials:
Material: The powder on powder decoration system can be used on shockproof
materials as aluminium, steel, glass, special plastics, wood.
Shapes: It can be applied to linear products, complicated or flat surfaces
that can be subsequently printed or modeled. The decoration can be easily
applied to heights of various centimeters.
Advantages of the Powder on Powder system:
-unchanged dimensional characteristics during the time
-high resistance to all the atmospheric agents
-Maintenance free, high productivity
-high fidelity of patterns, high U.V. Rays resistance, anti graffiti, low
cost
-Mechanical resistance, fire proof, use of Non toxic products for the
decoration
-possibility to recycle
-contribute in saving of forests ,
- Zero VOC(volatile organic content) ,hence environment friendly
Decorations: Permits accurately reproducing designs and natural elements
(wood, marble, ) Aluminum profiles coated using the Real Wood process can
only be approved with powders that have been Qualicoat approved and
provide the associated performance characteristics for external
weatherability. Mainly used in architural Aluminium for exterior use due
to the resistance properties of Qualicoat approved Polyester, Polyurethane
powder.
Sublichromy Process:
This process produces a wood effect pattern onto aluminum profiles using a
transferable media coated with special inks in a three-step process. When
placed under a significant combination of heat and low pressure, the
pattern is transferred onto a surface that has been previously coated with
a specifically formulated powder coating. The process requires special
film, powder for decoration process.
The procedure for Sublichromy is substrate pretreatment, basecoat powder
application, and sublimation process.
Substrate pretreatment: The pretreatment process is key to ensure that the
initial powder coatings layer achieves good adhesion to the surface and
exhibits good corrosion resistance. Pretreatments can include current
hexavalent chrome systems and more environmentally friendly
trivalent and chrome-free methods.
Basecoat powder application: A Qualicoat- approved polyurethane or
polyester TGIC or TGIC-free powder coating is applied to a coating
thickness of up to 80 μm and then cured at 180° to 200°C for approximately
20 minutes. This provides the base coat for the transfer of the ink design
onto the surface in the next stage. Mostly used for interior building
products, furniture ,can be used on exterior Aluminium products but with
limited performance guarantee.etc. Conclusion: Now it can be concluded
that the most awaited and exclusive premium REALWOOD patented technology
and system to imitate wood and other effects has arrived in India, brought
to you by General Trade of Italy in association of Spectra Consultech,
Pune. It is amply clear that the keen interest in the process was
demonstrated by visitors during Aluminium India 2008,where we had
exhibited the technology, system and decorated aluminium profiles,
windows, end use applications suitable for decoration include Aluminium
profiles, doors, sheets used in House buildings, Bunglows ,Commercial
complexes, offices, Shopping malls etc It can be included in the green
house building concept.
