Interpon Powder Coatings achieves Platinum SMaRT certification
FOCUS The latest trend in the chemical industry is the replacement of fossil-based fuels and chemical precursors by biobased alternatives, and it was inevitable that the vast amount of work in this field would soon become the topic for a technical forum. In March 2012, the first technical gathering will take place in Germany (p 8), and it is certain to attract many delegates. Industry news continues to confirm that the major players in the powder coatings market are still concentrating on strengthening their industrial platform in readiness for the predicted revival. An additional factor in my revival equation. How can it fail! Sid Harris
TECHNICAL The influence of nanoclays on the properties of an epoxy-based powder coating The beneficial effects of inorganic nanomaterials have been widely discussed in articles relating to industrial liquid coatings but the use of these materials in powder coatings has attracted little attention until the publication of an article by researchers at two Science and Technology Centres in Brazil. Their work describes a comparison of the effect of small additions of a conventional micron sized filler and corresponding amounts of a nano-sized montmorillonite (MMT) clay filler in an epoxy-based amine cured powder coating, upon the mechanical properties, thermal stability and barrier properties of the cured films. Tests were carried out on samples containing up to 4% of the two fillers in the clear epoxy powder coating. Above 4% loading of montmorillonite the gloss of the film deteriorated. Samples were prepared by conventional laboratory procedures and the powders were applied electrostatically to 2

pretreated steel panels and cured in accordance with the supplier’s instructions. Thermal stability was assessed by thermogravimetric analysis, DSC, and X-ray diffraction in different atmospheric conditions and the respective thermograms showed that there was a strong interaction between the MMT and the epoxy resin, forming a polymer/clay network, which restricted the molecular mobility and consequently increased the thermal stability of the polymer matrix, while the samples containing barium sulfate were claimed to have reduced thermal stability. Although little difference was shown at the 2% addition level of both fillers, it became apparent that thermal stability imparted by the MMT addition showed a marked improvement at the 4% level of modification. Electron microscopy revealed variations in the morphology of the fractured surface with increasing amounts of both fillers but the MMT particles appear to be interposed within the epoxy matrix while there is a weaker bonding with the barium sulfate and greater formation of agglomerates. Salt spray testing for 264 hours of exposure confirmed that the best results were observed with the MMT 2% samples, and the unfilled epoxy coating performance was superior to the 2% barium sulfate filled samples. It was concluded that the intercalated structures formed by epoxy/MMT nanocomposites with MMT interposed in the epoxy matrix provides better anti-corrosion and physical properties when compared to barium sulfate filled systems. Good adhesion, barrier and higher thermal stability were found at the 4% MMT loading but the gloss level was reduced.

INDUSTRY NEWS Interpon Powder Coatings achieves Platinum SMaRT certification Interpon Powder Coatings, the premier coatings brand owned by AkzoNobel, has been awarded SMaRT certification. The first coatings manufacturer to be certified, AkzoNobel Powder Coatings attained platinum status. An acronym for Sustainable Materials Rating Technology, SMaRT is the major external standard for product sustainability. It’s a carefully considered global certification that evaluates sustainability performance over a product’s life cycle and supply chain. It can apply to any product, from any industry, but products receiving SMaRT certification have openly documented their performance over a number of sustainability indicators ranging from minimizing the use of natural resources, to reducing waste and carbon footprint. “This is something we are really very proud of,” explained Jaap van den Akker, Manager Sustainability & HSE, AkzoNobel Powder Coatings. “Interpon powder coatings benefit from world class innovation and sustainable innovation is no different. Powder Coatings are recognized as an environmentally friendly coating option due to amongst other things, low VOCs and the ability to reclaim and recycle them. Being the first powder coatings manufacturer to achieve this certification proves we really are global leaders.” Companies achieving SMaRT accreditation must complete a thorough application process, enter into a legally binding contract certifying that the data submitted is accurate and prove that qualified professionals were used. A third party audit is also required and applicants must also renew and verify certification every three years in order to stay JANUARY 2012
FOCUS current with environmental trends. “It’s a continuous process,” continues Van den Akker, “We are working closely with all our stakeholders towards a sustainable future – we want Interpon powder coatings to be as sustainable as possible. We are constantly sourcing more sustainable and renewable raw materials and energy resources from our suppliers and focusing significant R&D efforts on reducing the ecological footprint at every stage of the process. Our ecological performance has been recognized as among the very best in the coatings industry and we use ecological efficiency analyses (EEAs) to reconfirm for both ourselves and our customers, that powder is a sustainable coatings material.” Press release from: AkzoNobel Powder Coatings Ltd, Building 24, Rijksstraatweg 31, PO Box 3, 2170 BA Sassenheim, The Netherlands, tel: +31 653 677 268, fax: +31 38 4200 467, website: http://www.interpon.com (1 Nov 2011)
AkzoNobel to build new coatings plant in China to meet rising demand AkzoNobel is planning to invest around €60 M to increase the production capacity of its Automotive and Aerospace Coatings business in China. This investment will provide additional momentum for the company’s accelerated growth strategy of achieving revenue of $3 bn in China by 2015, and strengthen AkzoNobel’s leadership position in the country’s automotive refinishes market. As well as constructing a new production facility in Changzhou, the company will build related warehousing, quality control laboratories, support facilities and offices on the new site. The project will increase capacity by around 25 M liters/y and the site is projected to be operational in early 2014. “This investment builds on last year’s acquisition of Prime Automotive and is all about meeting rapidly increasing customer demand,” explained Leif Darner, JANUARY 2012

Organa Garden’s IGT develops Duraspeed powder coatings for boat propellers Integrated Green Technologies LLC (IGT), the powder coating and equipment unit of Organa Gardens International Inc, has finished field testing its newly developed Duraspeed powder coating. Duraspeed is suited to be applied on boat propellers, drives, shafts, bow thrusters, trim tabs and keel coolers. The proprietary foul release coating has no environmentally harmful components and has been formulated to inhibit growth of marine life on the surface of the coated parts while at the same time, due to the smooth surface of the coating, minimizing resistance between the part surface and the water.
