FOCUS handsets. For the automotive refinishing segment, DuPont Korea has developed Cromax Pro, a refinishing paint designed to meet the need for low volatile organic compounds and improve the automotive refinishing process. BASF’s Sicotan, Sicopal and Lumogen ranges of pigments for car interiors provide very dark or black surfaces that remain cooler when exposed to sunlight, resulting in greater comfort and less energy for air conditioning. Japan’s Nippon Paint has developed highly stain-resistant coatings and resins from recycled industrial waste and recovered cooking oils. Compatriot Toyota introduced ‘3-wet-painting’ that allows users to paint one layer atop the other without waiting for the previous layer to dry. The company has also launched a highly scratch resistant clearcoat that restores itself when scratched. Related information and relevant data are further discussed.

Surfactant trends in coating applications The recent American Coatings Conference, organized by Vincentz Network and held in Charlotte, NC, on 12-14 Apr 2010, provided insights into the current issues being addressed by surfactant manufacturers for paints and coatings. DuPont has developed short-chain fluorotelomers under the Capstone brand name. It is currently phasing out its older Zonyl fluorosurfactants in favour of the Capstone range, which features undetectable levels of PFOA. Merck has taken a different approach to DuPont, developing branched structures combining two or more very short perfluorinated alkyl chains (OCF3, C2F5, C3F7) with a hydrophilic moiety. According to G Jonschker, these products demonstrate a comparable and in certain areas JANUARY 2011

superior performance to long chain (C8F17) fluorosurfactants, with the significant advantage that the short fluoroalkyl groups show no bioaccumulation. Sascha Oestreich of Cognis discussed the behaviour of a new class of renewable nonionic surfactants with 10 to 40 EO units in the hydrophilic portion. Compared to existing products used in emulsion polymerization, the new Cognis surfactants are reported to offer easier handling by forming no gel phases, showing low foaming behaviour and having low pour points. They also provide excellent stabilization performance. Cytec has developed an APE-free sulfosuccinate primary emulsifier, which was launched commercially in 2009 as Aerosol EF-810, and compares favourably with industrial standard benchmark surfactants.

Jotun: Paint to rebound after flood Jotun Thailand maintains that the Thai paint industry, which is currently down due to mass flooding in the country, would come up again on account of increased demand. In 2009 the paint sector declined by 15-20%. However, in 2010 the paint market is predicted to rise by 10%. Jotun Thailand, the Thai subsidiary of the Jotun Group based in Norway, is one of the leading decorative paints company in the country. In 2010, prices of paint raw materials such as titanium dioxide, epoxy and emulsions have got by about 50% owing to the supply constraints internationally and the situation is expected to continue. Paint prices hiked by 5% in May 2010 and Jun 2010 and are forecast to further increase by 5% in Dec 2010. Jotun Thailand recently launched Majestic EcoHealth, an alkyphenol ethoxylate-free environmentally friendly paint in Thailand. The paint is expected to garner sales of Baht 120 bn in

C O AT I N G S 2011, up by 50% over 2010. Besides, Jotun projects that the overall sales would increase by 11-12% to Baht 2.2 bn in 2010. Bangkok Post, 11 Nov 2010, (Website: http://www.bangkokpost.net)

Competition in the acrylic industry becomes fiercer China had the capacity to produce 1.12 M tonne/y of crude acrylic acid at the end of 2009. The country’s production capacities for various grades of acrylic acid and acrylates are listed and include high purity acrylic acid (214,000 tonne/y); acrylates (1.28 M tonne/y); ethyl/methyl acrylate (320,000 tonne/y) and butyl/octyl acrylate (960,000 tonne/y). A table lists the 11 main producers of acrylic acid manufacturers in 2009. They include Jiangsu Jurong Chemical Co Ltd (205,000 tonne/y of acrylic acid; 80,000 tonne/y of refine acrylic acid and 80,000 tonne/y of methyl/ethyl acrylate) and Shanghai Huayi Acrylic Acid Co Ltd (210,000 tonne/y of acrylic acid; 20,000 tonne/y of refine acrylic acid and 40,000 tonne/y of methyl/ethyl acrylate). A second table contains data regarding the annual supply of acrylic acid and acrylates in China, 2004-2009. In 2009, for acrylic acid, output was 836,000 tonnes (2008: 764,000 tonnes), imports totalled 55,100 tonnes (2008: 45,100 tonnes), exports amounted to 21,200 tonnes (2008: 36,200 tonnes) and consumption was 869,900 tonnes (2008: 772,900 tonnes). Various new projects that are under construction are listed, including those by CNOOC (140,000 tonne/y of crude acrylic acid and 160,000 tonne/y of acrylates) and Jiangsu Jurong Chemical Co Ltd (320,000 tonne/y of acrylic acid). The main end use for acrylic acid is acrylates production (65.6%), superabsorbent polymers (consuming some 90,000 tonne/y of high purity acrylic acid) and detergents. Speciality acrylates have growing uses in the 7
