Paint makers turn to Bharat for growth
The rural market has grown at a rate of around 20% a year, which is way above the growth
Like other consumer goods companies, paint makers have also started looking beyond cities. Their New Year resolution is to enter the legions of villages and small towns or increasing their reach if they are already present there. For, they believe only Bharat promises accelerated growth.

“Rural market is a big hope for us. It is driving our sales. We are expanding our distribution network in these locations to make the most of this opportunity,” Ramakanth V Akula, president (decorative), Nippon India, told Business Standard.

"Due to good monsoon rural India has bucked the trend. Rural centres in states like Punjab and Tamil Nadu are driving major part of our sales," Abhijit Roy, managing director of Berger Paints in India, said <more>

Akzo Nobel Q3 net declines 46.65 per cent to Rs. 27 crore
New Delhi: Paints and coatings company Akzo Nobel India on Thursday reported a 46.65 per cent decline in net profit at Rs. 27.01 crore for the third quarter that ended in December 2013, due to special dividend payout.

The company had posted a net profit of Rs. 50.63 crore for the corresponding quarter in the previous fiscal year, it said in a statement.

However, net sales of the company rose to Rs. 643.93 crore for the quarter under consideration from Rs. 594.05 crore in the same period a year ago.

"The special dividend payout in this financial year has led to a reduction in our cash surplus and also resulted in a drop in investment income, which is largely responsible for the PAT being lower when compared to the previous year's corresponding quarter," Akzo Nobel India whole-time director and CFO Himanshu Agarwal said.

Berger shows Malayalis how to be house proud even in monsoons
New campaign by Rediffusion Y&R Kolkata for Berger Paints’ WeatherCoat All Guard shows how the new product helps protect houses from rain damage
Berger Paints has launched a new campaign for their exterior paint brand, WeatherCoat All Guard. Conceptualised by Rediffusion Y&R, Kolkata, the campaign aims at the Kerala audience and therefore uses a lot of Kerala nuances.
The idea behind the campaign came from the belief that Malayalis are house proud. They build houses and associate their names to the structure. These houses are then known by the name and not by the street address. To make sure that the product resonates with this attribute, Berger Paints had to emotionally connect with the audience.
According to research done by them, rain is considered to be the single biggest threat to the well-being of a house. WeatherCoat All Guard, with its silicon additives, helps keep houses protected from rain and looking fresh.
Suraj Das, Group Product Manager, Berger Paints India, said, “The advertisement is based on the consumer insight that people in Kerala are really proud of their houses. The ad takes this insight and creates a story around a house which after painting with Berger WeatherCoat All Guard has become a landmark in the city. WeatherCoat All Guard has silicon that drives water away and keeps the house looking fresh and resplendent for years to come. It signs off on a note saying ‘Long lasting and beautiful house is an owner’s pride’.”<more>

AkzoNobel Powder Coatings to relocate two manufacturing facilities in China
December 20, 2013
AkzoNobel Powder Coatings today announced its intention to relocate its manufacturing facilities in Ningbo and Suzhou to the Chang Zhou National High-Tech District by the end of 2015.

The current location of AkzoNobel’s Ningbo site has been designated as a future residential zone in the Chinese government’s 2010 urbanization plan, therefore making it unviable for future operations. Discussion with the local Government resulted in Chang Zhou being identified as a suitable alternative location. At the same time, AkzoNobel will also relocate its Suzhou plant to Chang Zhou. This move will further support the company’s integrated business strategy focused on ensuring sustainable growth of its business in China.
“The relocation of our Ningbo and Suzhou facilities to Chang Zhou presents an opportunity to upgrade our manufacturing capacity and capability in the region, allowing us to provide even better service to our customers” commented John Wolff, Managing Director AkzoNobel Powder Coatings. “The move will also create opportunities to better leverage synergies amongst AkzoNobel businesses and improve operational performance in line with AkzoNobel’s global strategy.”<more>

A chameleon in the physics lab
Cambridge, Mass. – October 21, 2013 – Active camouflage has taken a step forward at the Harvard School of Engineering and Applied Sciences (SEAS), with a new coating that intrinsically conceals its own temperature to thermal cameras.
In a laboratory test, a team of applied physicists placed the device on a hot plate and watched it through an infrared camera as the temperature rose. Initially, it behaved as expected, giving off more infrared light as the sample was heated: at 60 degrees Celsius it appeared blue-green to the camera; by 70 degrees it was red and yellow. At 74 degrees it turned a deep red—and then something strange happened. The thermal radiation plummeted. At 80 degrees it looked blue, as if it could be 60 degrees, and at 85 it looked even colder. Moreover, the effect was reversible and repeatable, many times over.
These surprising results, published today in the journal Physical Review X (an open-access publication of the American Physical Society), illustrate the potential for a new class of engineered materials to contribute to a range of new military and everyday applications.<more>

Pitcher perfect
Carnivorous plant inspires protective coatings
Pitcher Plant
A tropical carnivorous plant – the pitcher plant – which traps its prey inside its body with a virtually frictionless surface is inspiring a new generation of coatings capable of repelling liquids including blood, oil, honey and even ice.
Nature is well-known for its ability to repel liquids with lotus leaves, rice leaves, butterfly wings, mosquito compound eyes, cicada wings, red rose petals, gecko feet, desert beetles, and spider silk all having the ability to remain dry.
However, the pitcher plant or Nepenthes, which is found in countries including Australia, Malaysia and Madagascar, has a special adaptation which creates a near frictionless surface with unique self-healing properties.
The ability to repel liquids and contaminants has important applications to industry and everyday life. Coatings are needed to help stop the formation of life-threatening bacteria on medical instruments, ice build-up on air planes, fouling on ship hulls, anti-corrosion and the efficient transportation of products like crude oil by pipeline.
The pitcher plant is different to some other nature-inspired adaptations by ‘locking-in’ a lubricant layer onto the surface of its skin which cannot be penetrated by another liquid and is more damage tolerant. The result is also fatal to the plant’s prey – insects and small frogs – which are unable to climb out of its smooth, deep, tubular-shaped body.
A team at Harvard University have now been able to mimic the pitcher plant’s inner skin design to produce a transparent coating capable of being economically applied to almost any object – large or small.
The multi-stage coating process involves attaching a thin, but rough layer of porous silica particles which are used to lock-in a lubricating layer onto the surface to be protected. Its diverse applications could include acting as an anti-graffiti coating on walls or on medical implants to aid blood flow.

New optimized coatings for implants reduce risk of infection
Researchers at Aalto University have developed a method of selection of new surface treatment processes for orthopaedic and dental implants to reduce the risk of infection.
Implants are commonly made from metals such as titanium alloys. These materials are being made porous during processing used to prepare them for medical use. Whereas this is important to ensure good contact between the implant and the bone, this also allows dangerous bacteria to adhere and grow both on the surface as well as inside leading to increased risk of infection.

"Our work has focused on developing an analysis of surface treatments for commercial implants which reduces risk of infection," said Professor Michael Gasik at Aalto University. "What we wanted to do is find a way to avoid the formation of any undesirable products during the processing of the implant." "At the same time we needed to make sure that the bio-mechanical properties of the implant would remain intact and, even more, become better."
A thin coating of a biomaterial called Hydroxyapatite (HAP) or bioactive glass (BAG) is typically applied to orthopaedic and other implants to alter the surface properties. Such coatings improve the body ability to recognize a foreign object in a more friendly way and promote implant integration into surrounding tissues. During the heat treatment process, excessive stresses can cause premature cracking and removal of the coating layer. This can lead to the development of unsuitable compounds and increase the risk of infection.<more>

Elephant killed zookeeper due to new paint, experts suggestElephant: The trainer was killed by an elephant at the Dai Nam Tourist Centre (file picture)
Experts suggested that the new paint odor emitted from a mahout might have irritated the elephant and enraged it into whipping the zookeeper, who had been training it for years, to death at a famous tourist complex in southern Vietnam on Monday.
>> Elephant whips its keeper to death at tourist center

The theory was released after the death of 28-year-old Doan Huu Tai, an elephant keeper at the famous Dai Nam Tourist Center in Hiep An Ward, Thu Dau Mot City, Binh Duong province.
On December 23 afternoon Tai stepped into the cage of a 9-year-old elephant named Ka, weighing about 2 tons.

He had a can of paint in his hand and was about to begin painting the cage when the animal suddenly raised it trunk, twined Tai’s body and lashed him against the wall of the cage.

The elephant then threw Tai into its water basin. Tai’s head smashed against the wall of the cage. He died later due to serious brain injury.

Dear Joe,
I'm a manufacture of powder coatings at VietNam. We have a problem in product as follows:

The reclaimed powder is being sprayed on object, but it has very poor transfer efficiency. ( I know: The reclaimed powder should be added with fresh powder at ratio 70/30 or 60/40, but my customer, he's spraying the reclaim alone. The particle size of fresh powder is 5 microns to 80 microns, D50=28 microns, Percentage of particle size 5-10 microns about 10%). Would you suggest for us how to enhance transfer efficiency with reclaimed powder?

I look forward to receiving reply from you soon.

Thank you and best regards.

Tu Long Nguyen

Dear Tu Long,

Thank you for your question. Indeed this is a challenge. As you know - the best solution is to correct the root cause which can be delineated into two issues:

1. Improve first pass transfer efficiency to minimize the creation of overspray which needs to be recycled. This can be accomplished by regular gun maintenance, always ensuring excellent earthing of the parts to be coated, keeping racks clean and using powders with good particle size distribution (minimal fines and coarse particles)

2. Only introducing a low level of reclaim to the virgin powder. Less is always better but it is wise to never exceed a 30% reclaim to virgin powder ratio.

Obviously you need help now because your customer insists on spraying high levels of reclaim. There is hope however the solution is imperfect. It is possible to improve the fluidization and application performance of reclaim powder. The use of a dry-blend additive is worth attempting as a solution to your customer's application problem.

These materials are based on fumed silicas that have been surface treated to make them hydrophobic. They are supplied as agglomerates of very fine particles of silica typically around 0.2 microns in diameter. Think of them as clusters of grapes. These agglomerates can be quite large and therefore will create defects in the finished powder if they have not been adequately de-agglomerated. Hence the mixing process used to disperse the dry-blend additive is important.

Here are a few guidelines for incorporating a dry-blend additive to the powder. A good starting point is a concentration of 0.2% by powder coating weight. Mix the modified powder coating thoroughly. I suggest a V-blender or something similar to accomplish this. After mixing I recommend sifting the powder through a relatively coarse screen (80 mesh or 175 microns). This can further de-agglomerate the dry-blend additive to help minimize the possibility of "seeds" due to large agglomerates.

Please send me a personal email message and I will provide specific details on the best material to try. It is based on a silane treated hydrophobic fumed silica.

The modified powder will fluidize and transport through the application system much better than unmodified reclaim powder. I would pay close attention to the film thickness of the coated parts.
Thicknesses less than 50 microns (2.0 mils) may exhibit "seeds" or defects caused by the protrusion of silica agglomerates.

Best of luck Tu Long. If possible please provide an update of your progress.

Kind regards,

Joe Powder

I have a few questions for you regarding the powder coating process and defects. I hope you don’t mind taking the time to answer them for me. Here we go:

Is there any indication, that static electricity could be causing defects such as fisheyes, cratering or BITS in the powder coating process? Is any static electricity generated in any one of the powder coating systems? What products are commonly used when repairing the types of defects noted above? And, last, but not least, how are powder coating companies insuring that dust and lint are at a very minimum prior to coating their products?

Joe, thank you very much for your time. I really appreciate it.

Vicky DeRoven

Ace-Tex Enterprises

Hi Vicky,

Wow, you have a lot of questions. Let me break them down.
Static electricity - yes there is static electricity and from more than one source when dealing with powder coating application. As you probably already know powder coatings are electrostatically charged typically by a corona mechanism near the tip of the business side (outlet) of the spray gun. This works by very high voltage (80,000 to 100,000 volts) being delivered to the electrode. This high voltage ionizes the air creating a field of electrons or negative charge. (Don't worry the current is very small, typically micro- amps so the process is relatively safe.) The powder is pneumatically conveyed into this electrostatic field, picks up a charge then heads to the nearest ground. The object of the game is to make your parts the closest ground and then the powder deposits on the surface of said part.
So lots of static electricity is generated by the spray system. It's important to note that static electricity is generated elsewhere in the finishing system. The mere fact that powder particles are being conveyed into fluidizing hoppers, through powder pumps, hoses and spray guns creates static charges. This extraneous generation of charge affects powder deposition and can influence transfer efficiency.

Does static electricity cause fisheyes, cratering and "bits"? Probably not. Very characteristic defects are caused by electrostatics however. Excessive charge can build up in a powder coating layer if the powder is applied too thick, too quickly. This phenomenon is known as back ionization. The build-up of charge causes powder particles to microscopically burst away from the substrate. This causes micro defects that resemble volcanoes. These defects cause a rumpled appearance that looks more like localized macro orange peel for lack of a better description.

Fisheyes are caused by a different mechanism and are more distinct in their appearance. Fisheyes are created by a significant differential in surface tension between a molten powder film and a contaminant. Common contaminants are lubricants and oils. Silicone lubes and penetrating oil (e.g. WD-40) are some of the worst actors. Fisheyes are gross defects characterized as deep circular voids in the coating film that reach the substrate. Craters are ambiguously defined as defects similar to fisheyes but smaller in diameter. Craters often do not reach the surface of the substrate and typically look like dimples.

 As for "bits" I imagine you are referring to unmelted protrusions in the finish of the cured powder coating. These are not caused by static electricity. Common sources of "bits" are environmental dirt (oven, spray area, unclean application equipment, etc.), unclean substrate or dirty powder coating. They are typically more prominent at thin films (i.e. < 1.5 mils). If the preponderance of "bits' decreases with thicker coating films then you can suspect either the powder or a contaminated substrate surface. If film thickness is not a factor then the contaminant is probably environmental and is deposited on the powder after it has been applied.

Regarding repair - fisheyes, craters and "bits" need to be buffed with an abrasive (Scotchbrite™ or 200 grit sandpaper), the surface wiped (e.g. acetone), dried and recoated. Alternately you can consider using a liquid paint based touch-up if the repair is small and localized. Be careful however as the touch-up may not meet the performance of the original powder coating finish.

Are powder coating companies doing everything to minimize dust and lint? Do you mean powder applicators or powder coating manufacturers? High quality coating shops are very clean with isolated application areas that use filtered make-up air. Their processes are carefully monitored and controlled. It's fairly easy to discern their quality level with a visit and tour of their finishing operations. As for powder coating manufacturers - there is a range of quality. Large producers have prominent quality programs but this doesn't necessarily mean they clean their equipment well or that they produce perfectly clean products. If you can tour their facility it will speak volumes on how they manage their manufacturing and quality programs. Word of mouth is also a good means to learn about a supplier.

I hope this helps you better understand the powder coating process and how defects occur. Please let me know if you have any more questions.

Best regards,

5th Leading International Trade Fair for Industrial Coating Technology from 8 through 11 April 2014 in Karlsruhe (Germany)

PaintExpo – Answers for Demanding Coating Requirements
Ever greater demands are being placed on surfaces, and thus on coating technologies as well. On the one hand, efficient use of resources, individuality and environmental compatibility are decisive in this respect. On the other hand, new ranges of applications, quality and flexibility play a significant role as well. With numerous new and further developments, the exhibitors at the 5th PaintExpo will provide answers on how these challenges can be met. The leading international trade fair with more than 400 exhibitors will take place at the exhibition centre in Karlsruhe from the 8th through the 11th of April, 2014.

Whether motor vehicles, consumer goods, machinery and equipment, communications, electronics, architecture, medical technology or energy are concerned – there’s hardly an industry sector in which coating technology is not ever-present. A great variety of functional and decorative requirements need to be fulfilled for various surfaces. And it’s always important to apply coatings or paint using as little material and as few resources as possible, as ecologically as possible, and with the best possible quality – regardless of the base material.

Trends in Efficient Coating
The exhibitors at PaintExpo offer new solutions and further developments to this end, throughout the entire process sequence for liquid painting, powder coating and coil coating. For instance, where the pre-treatment of metallic substrates is concerned, iron phosphating which becomes effective at temperatures of as low as 30 to 35° C, instead of 40 to 60° C, as well as nano-ceramic systems, are becoming more and more prevalent. In the meantime, products based on renewable raw materials are also available for the pre-treatment and cleaning of components made of steel, iron and aluminium. Alternative processes such as snow blasting and plasma cleaning are also on the advance for the pre-treatment of plastic parts.

Paints with Optimised Function
In the field of painting, there’s a trend towards systems which fulfil decorative as well as functional requirements. For solvent-based paints and clear coats used on metals, plastics and wood, additives are available which provide the paint with, amongst other things, antimicrobial characteristics. These are based on organometallic substances which have an ionising effect. These substances are also being used in newly developed powdered enamels with antimicrobial effect. For components used in, for example, construction and farm machinery, as well as in outdoor applications, requirements have become stricter for corrosion protection and resistance to UV radiation and weathering. These requirements can be fulfilled effectively and ecologically with an epoxy-based primer powder which is free of zinc and heavy metals. It fulfils corrosion protection requirements up to C5-I lang, and can be painted over with powder coatings as well as liquid paints. The corrosion protection primer is offered as a solution which is ideally matched to the substrate to be coated (ferrous metals, substrates with sharp edges, castings). Another newly developed 2-layer powder coating solution for highly effective corrosion protection allows for coating without energy-intensive, intermediate cross-linking. Primer and top coat are applied to the component using a powder-on-powder process based on tribotechnology, and both layers are subsequently cross-linked in a single step.

UV Technology On the Advance
The significance of UV technology continues to grow for plastic as well as metal parts, because more and more complex workpieces can be coated with the help of this method. UV curing takes place in an inert gas atmosphere, for which CO2 or nitrogen is used to reduce oxygen content. This prevents the radicals which are required for the polymerisation process from reacting with oxygen in the atmosphere, thus ruling out the possibility of a co-called oxygen inhibition. Curing can thus take place at larger intervals, and areas which are subjected to significantly less UV radiation are better cured as well. In addition to gas discharge tubes, LED radiators are also used for curing UV paints in the meantime.

Nitrogen Instead of Compressed Air
In the interest of material efficiency for the application of solvent, water-based and high-solid paints, alternative atomising gases are also being tested. The use of nitrogen allows for material savings ranging from 5% to 45%. Beyond this, a corresponding process which, in the meantime, has proven its worth in various series applications in the automotive industry, offers advantages with regard to painting quality, throughput and system availability.
Innovations and further developments will await visitors throughout the entire exhibition programme at PaintExpo which covers coating equipment, application systems and spray guns, liquid paints and powdered enamels, automation and conveyor technology, cleaning and pre-treatment, drying and curing, environmental technology, pneumatics, compressed air supply and exhaust purification, water treatment, recycling and disposal, accessories, measuring and test technology, quality assurance, paint stripping, job-shop coating, services and technical literature as well as identification, printing and packaging.
The WTT Expo trade fair for industrial heating and cooling technology and the HallTec trade fair for technical building equipment for industry and the commercial trades will take place concurrent to PaintExpo 2014 at the Karlsruhe Exhibition Centre.
