China paint additives growing strong
F O C U S phosphating processes, with dramatic improvement in the ecological field and improved economics. The process is free from heavy metals such as nickel, manganese, and zinc, offering reduced risk to operators and low waste disposal costs. They are also free from phosphate ions. This new conversion process gives nanometer thin coatings, in contrast to phosphate conversions, which are within the micron range. They are based on a combination of a nanostructured ceramic type metallic oxide, with metals such as titanium and/or zirconium. The nanoceramic coating is produced rapidly and the deposited film of metal oxide nano-particles reaches a plateau within 20 to 30 seconds. The nanoceramic conversion is industrially applied in a multistage process. A typical process includes an alkaline cleaning step, rinses, the conversion itself, and a last de-ionized rinse. A unique feature is the application at ambient temperature of the new conversion. This process is shorter than the conventional iron phosphate process, which can include a further passivation step. Zinc phosphate treatment is even longer since it includes an activation step for the nucleation of the zinc phosphate crystals over the metallic substrate. Performance tests were carried out by chemists at Henkel who prepared panels and parts treated with different industrial spray application processes in the US and Europe, comparing the new process with standard spray applied iron and zinc phosphate systems. The panels were coated with various paint finishes including a high solids acrylic paint produced in the US and a TGIC-free polyester powder coating, produced in Europe. The metal substrates were cold rolled steel (CRS), electrogalvanized steel (EG), and aluminium of standard quality (AL). The panels were subjected to neutral salt

spray (NSS) to ASTM B-117 and corrosion testing to GM 9540 P standard. Cross hatch tests were performed to assess the adhesion of the coatings. Results are tabulated in the Henkel article and are fairly consistent for all substrates and paint systems. Corrosion testing and adhesion performance for the powder coating gave the following figures for under film creep. The new process ( BonderiteNT-1) on CRS after 504 exposure to NSS showed creep of 1.5-1.8 mm compared to Bonderite 1080 iron phosphate with creep of 5.0 to 14.0 mm. On EG panels creep values were: Bonderite NT-1 2.5 to 5.0 mm and Bonderite 1080 6.2 to 8.0 mm. Aluminium panels gave creep values of 2.0 to 3.0 for both pretreatments. Paint adhesion tests were good in almost all conditions but there appeared to be better reliability with nanoceramic conversion. In some cases the performance of the new treatment matched the performance of zinc phosphate treatments.

MARKETS China paint additives growing strong According to Frost & Sullivan, the Chinese paint additives market was worth $401.7 M in 2004. This is forecast to increase to $954.8 M by 2011. Datamonitor predicts that the Pacific Asian paints and coatings market will rise from $21.2 bn in 2004 to $40.2 bn by 2010. Sales volume is expected to rise from around 7 M tonnes in 2005 to 12 M tonnes by 2010. Rohm and Haas began construction of a new paint and coatings facility in Foshan Sanshui Industrial park in Guangdong, China in Dec 2005. Akzo Nobel opened a new powder coatings plant in
C O AT I N G S Langfang, China in Jan 2006. The firm aims to have Chinese sales of €1 bn by 2010. Degussa is planning to open its new colorants production plant in Shanghai in 2006. The Chinese paint additives market will be boosted by a trend towards environmentally-friendly coatings. However, rising raw material and energy costs and pressure on prices could have a restraining effect. A table gives value and % growth for the Pacific Asian paint and coatings market 2001-2004 and estimates 2005-2010.

High prices for raw materials and strong competition promote flexibility The article discusses the outlook for the German coatings industry in 2006 and highlights the performance of 2005. Germany manufactured around 2.2 M tonnes (+1.6%) of paints and coatings in 2005. In 2004 the production volume had increased by 3.8%. Turnover with paints and coatings in Germany increased from €4.7 bn in 2004 to almost €5 bn in 2005. The upturn is attributed to price increases, which were sparked by higher costs for raw materials. The performance of individual segments is discussed. Domestic consumption increased by 2.3% in 2005 and exports increased to around €1.8 bn. Raw material prices are expected to remain high in 2006 and the possible effects of the new REACH regulation are discussed. High technology coatings are seen as the future engine for growth in the German paints and coatings market. Figure 1 illustrates that German coatings manufacturers considered the domestic consumption to be weak, total business satisfactory and the export situation very good in 2005. Figure 2 sections the
