We need the following,
High Heat Performance. Powder coating on plastics
by Ian Montgomery, Marcel Verhagen
Powder coating is a fast growing technology due mainly to its environmental benefit, particularly the elimination of solvents and related compounds that are emitted into the air in conventional liquid paint. Powder coating has been traditionally used with metal substrates, however, the need for greater design freedom has led to industry demand for technology suitable for plastic substrates.
Lightweight, high performance and adaptable plastics offer many advantages over metals in applications ranging from mobile phones and TVs to automotive body panels and tractor hoods.
The challenge has been finding successful approaches to the key issues of powder coating these materials conductivity to attract the coating and high heat performance to withstand the cure cycle. There have been major paths to this goal.
Reaching the objectives
The first approach is aimed at using a primer to give the surface of a non conductive plastic substrate enough conductivity to allow powder coating to adhere. This process has some disadvantages because it requires a liquid to be applied and cured prior to the powder coating process. Additional issues include costs of both liquid and powder application equipment, the need of multilayer where a single layer of powder coating could fit the requirement and loss of some environmental advantages of powder coating (ie. elimination of volatile organic compounds [VOC] emissions.
The second technology is thermal application or flocking. In this process, the substrate is pre heated and the powder is applied to the hot surface. This heat causes powder to stick to the surface. The part is then cured in the same way as a conventional powder coating applied at room temperature.
These two process can only be used with plastics that have high heat deflection temperature ( a measurement of a plastic's resistance to deform at higher temperature} or plastics filled with glass or minerals that can increase stiffness at higher temperature. However the choice of substrate is still somewhat limited and does require the end user to have a good understanding of the performance of the plastic substrate during the curing process for the powder coating.
The third alternative is not really a process but rather the result of new developments in conductive plastics. Specialized plastics substrates have been developed to permit the direct application of powder coating to the surface with no pre treatment or pre processing ultimately giving the coater the option to hang plastic substrate next to metal substrate on a powder coating line. This technology has been under development for a number of years at SABIC Innovative Plastics. Plastics leading to a product line called Noryl GTX resin.
Noryl GTX resins are environmentally responsible material which are optimised for powder coating. they contain conductive filers that eliminate the need of apply of electrostatic primers, which can emit harmful solvents and related compounds into air. In powder coating applications Noryl GTX resins can replace metal substrate, eliminating costly and potentially hazardous chemical pre-treatment and offering increased design freedom. Also the material makes it possible to powder coate metal and plastic on the same production line, which enables economics of scale and avoid color mismatch between powder coating and injection moulded plastics.
Noryl GTX an alloy of polyamide (PA) and polyphenylene ether (PPE) offers an outstanding balance of properties, including mechanical performance, chemical resistance and heat resistance, which makes it an excellent candidate for many industries and applications . The ability to be modified for use in electrostatics processes and to withstand cure temperature up to 410 degree F (210 degree C) enables the material to be powder coated using most powder chemistries found in market place, including polyester, epoxies and hybrids.
Compared to the typical liquid painting process, conversions to powder coating can reduce VOC emissions up to 98% and results in an overall coating saving over 49%. Further, they offer OEMs and their supply chain partners the flexibility to replace metals with light weight high performance plastic or to run multiple materials on the same coating line.
Although there are some PA grades that can be liquid or powder coating directly, the addition of PPE resin allows the resin to solve drawbacks of PA, it reduces moisture uptakes that would normally require significant drying prior to coating, it reduces warpage, and it lowers density for weight saving up to 25% over glass filled PA, where the glass is required for PA for heat resistance in the powder coating process.
While many conductive resins used in liquid coating environments are suitable for powder coating applications, some grades have been confirmed to give them a wider processing window in powder coating applications. Table 1 shows key properties of these grades.
Unlike conventional plastics that must be coated with electrostatic primer, or metals that must be chemically pre treated to remove grease, Noryl GTX resins require only a washing step prior to beginning the powder coating process.
Besides PEE/PA aloy, SABIC Innovative Plastics introduced as of January 2008 a PPE / PBT aloy (Noryl LMX), which alo can be used for powder coating or electrostatic paintings systems. The main objective to launce this grade is the reduction of moisture pickup during handling the moulded applications. Compared to PPE/ PA alloy the PPE/ PBT alloy has a moisture uptake of 0.15%
Noryl LMX is produced in the same process as the conductive PPE/ PA alloy.

DENR has been monitoring the presence of perfluorooctanoic acid, or C8, in the well. The level increased from 7 parts per billion in 2006 to 17 parts per billion last year.<more>
Money must be found to fix the lead paint mess in all of the older houses
Who is responsible for removing poisonous lead paint -- homeowners, landlords, municipalities, the feds, the paint manufacturers?
More than 93,000 older Delaware homes may contain lead paint that can harm brains and central nervous systems. Very young children are especially vulnerable. The toxins in lead paint can cause impaired hearing, hyperactivity, poor coordination, decreased growth, muscle pain, learning disabilities, memory problems and attention deficit disorder.
Lead paint was taken off the market in 1978 but its legacy lingers. According to the Centers for Disease Control and Prevention, 1.7 million children ages 5 and younger are affected by lead poisoning
Delaware and other states are still cleaning up the mess, quite literally. As it crumbles and chips in homes built before 1978, lead paint still poisons.
Getting the lead out costs about $1 million a year in Delaware alone.
Officials here say only 246 units will receive either full lead-paint removal or limited interim control treatments this year because the average cost of abatement is $15,000 a unit, and fixing one Wilmington unit cost $40,000.<more>

It has a colour palette of 66 colours available through a tinting system across four groupings: Waterscapes, Atmosphere, Botanical and Earth. <more>
China's paint industry becomes world's second largest
BEIJING, Apr 01, 2008 (AsiaPulse via COMTEX) -- -- China has become the second largest paint producer and consumer in the world propelled by booming real estate, auto and shipping building sectors.
Global paint manufacturers have moved their production capacities to China in recent years.
The world's top paint and coating producer Akzo Nobel recorded US$1.03 billion of sales revenue in China last year, up 16 per cent year-on-year.
By 2012, Akzo Nobel is expected to realize US$2 billion of sales revenue in China, according to Anders Brostm, president of Akzo Nobel China.
The production value of the world's paint industry exceeded US$82 billion in 2002 with an annual growth rate at about six per cent, according to the just concluded 5th China international Exhibition for Painting Chemical Materials in Beijing.
Currently, the output of top ten paint producers in the world accounts for one third of total output, boasting a 60 per cent market share. <more>
Berger Paints India acquires Poland's Bolix from Advent Intl for $38.6 mln
MUMBAI (Thomson Financial) - Berger Paints India Ltd. said it has acquired Poland-based Bolix S.A. from private equity group Advent International for $38.6 million.
The purchase, which will be made through a Berger unit in Cyprus, is subject to clearance by the Polish Anti-Monopoly Office.
Bolix is a provider of external insulation finishing systems and manufactures dry plaster mixes and acrylic colours.<more>
Paint makers plan to increase prices next month
MUMBAI: Spruce up colours on your walls soon or be prepared to shell out more for the same as prices of solvent-based paints seem poised to move northward.
Paint manufacturers are lining up price hikes to combat the hit on their bottomline due to the continuing increase in global crude prices, which have been scaling newer peaks each passing day. Oil prices have risen 79% in the last year.
Petroleum compounds form one of the major raw materials used for making these paints.
Abhijit Roy, vice-president, sales and marketing, Berger Paints India, said, “There has been a rise in input prices for our industry, especially in solvent-based products. It is not always possible to hike prices, but now it has started hurting our bottomline. There will be an increase of about 5% in prices in a month.”
He added that the impact of these high prices would be more for companies like Berger and Nerolac as oil-based paints constitute a high percentage of their sales.
Other manufacturers are also indicating price hikes. Ashok Saini, vice-president, special projects, Kansai Nerolac Paints, said, “Till now we had the cover of the rupee appreciation, but now that has also gone. For decorative paints it would be easier to hike prices, but it would be difficult for industrial products as they are bought in bulk.” <more>

Crown Jewel of Akzo Nobel put up for sale
Akzo Nobel has put its UK Crown Paints business up for sale with a £200 million price tag, As a result of the deal agreed with the European Commission to gain clearance for its £8 billion takeover of ICI, completed in January.
Akzo has until late June to sell its Lancashire-based Crown business and has now reportedly appointed investment bank Greenhill to find buyers. It is thought that the sale could attract the interest of US firms such as American buildings materials and coatings company Sherwin-Williams, as well as PPG Industries and RPM International.
The ICI deal saw Akzo Nobel take control of Britain's top two paint manufacturers, with newly acquired Dulux the top player in the market, followed by Crown.
Crown is thought to employ around 1,400 people at three sites across the UK; its main site in Darwen, Warrington and Hull. Sites in Dublin and Belfast are also understood to be up for sale as part of the agreement.
The Dutch firm said it was confident that the Dulux brand would be retained, but it was unclear if ICI as a name would survive. Alongside the Crown sale, Akzo is also selling ICI’s adhesives and electronic materials business to German chemicals firm Henkel, for £2.7 billion.
Katayama Chemical is working to bring to market flame-retardants, based on vinyl phosphonates, that significantly reduce the natural escape of flame retardants from plastics into the atmosphere.
Using a 140-L reactor at its Amagasaki plant in Japan, the Osaka-based company intends to manufacture several hundred kilograms of dimethyl vinyl-, diethyl vinyl- and diphenyl vinyl phosphonate, and diphenyl vinyl phosphine oxide. It will use these to make flame-retardants on a trial basis for data collection and evaluation, looking at such aspects as their chemical properties, toxicity and marketability.
The testing process is to be completed in approximately one year, upon which Katayama intends to commercialise the product if the results are favourable.
A multi-stage process is currently used to introduce vinyl groups into phosphorous compounds using highly toxic materials such as phosphorous chloride and phosgene, and it is considered difficult to carry out large volume synthesis. But Han Li-Biao, a senior staff member at the Research Institute for Innovation in Sustainable Chemistry under Japan’s National Institute of Advanced Industrial Science and Technology, has succeeded in developing a mass-production process for vinyl phosphonates.
Katayama decided to take on the commercialisation of the one-step high-yield process, which uses low cost cationic catalysts, as it believes that the products have potential as environmentally sound alternatives to brominated flame-retardants.
Besides the anticipated use of vinyl phosphonates in flame-retardants for plastics, fibres and electronics’ substrates, they hold promise in the medical sector as pharmaceutical intermediates for cancer drugs and also as agrochemical intermediates, because of their optical activity.

3. Electrical hazards
The main sources of electrical hazard are :
(i) inadequate or defective earthing (grounding) systems leading to build-up of static and subsequent sparking or shock.
(ii) breakdown or overheating of the electrical equipment leading to fire
3.2.1 The contact between the workpiece, carrier jigs and conveyor should be designed and regularly tested to ensure an adequate earth is maintained at all times. Jigs should be designed to avoid any unnecessary build-up of coating. They should be cleaned on a regular basis to maintain correct contact. Automatic cut-out or warning systems should be installed, wherever
practicable, to constantly monitor the efficiency of the earthing system between the jig and the conveyor.
3.2.2 Metal objects to be coated should have a resistance to earth not exceeding 106 W.
3.2.3 Floors and other surfaces with which operators can make contact should be conductive and have a resistance not exceeding 106 W. Non-conductive materials can be coated with conductive floor compounds and coatings.
3.2.4 As an additional precaution, all components of the spraying facility should be connected together through an equipotential bonding system. This should include all electrical equipment enclosures, metal floors, ceilings, fences, partitions, and conveyors as well as the
3.2.5 As an alternative to physical earthing of the workpiece, ionising devices can be used to discharge any accumulated electrostatic charges. The device should be sited as near as possible to the work piece.
3.2.6 Conveyors should be designed to minimise swinging of the work piece.
3.2.7 Regular maintenance and cleaning programmes should be introduced to ensure that dusts are not allowed to build up on electrical equipment and that ventilation ducts and cooling fins are
kept clean and unobstructed.
3.2.8 Only the spray gun(s) and associated electrical cables and powder supply hoses should be sited inside the booth. If the siting of other electrical equipment, including the HV generator,
in the booth or adjacent areas is unavoidable, this equipment must meet the requirements of EN 50050 ( handguns )and EN 50 177 ( automatic guns ) and must be dust tight to Standard IPX.
3.2.9 Operatives should wear anti-static overalls, non-insulating gloves and anti-static footwear meeting the requirements of ISO 2023/2024.
