Light enhanced biocides
F O C U S paints for both the OEM and vehicle refinish sectors. The company is a major supplier of coil coatings, powder coatings and foil coatings. Engelhard Corp is a “surface and materials science” company, with sales revenue for 2005 reported as $4.4 bn. Engelhard is one of the world’s largest suppliers of catalysts and it now claims a market share of about 33% of the global market for vehicle emission catalytic converters. Engelhard’s sales revenue of $4.4 bn in 2005 breaks down as: 44% from Materials Services; 23% from Environmental Technologies; 15% from Process Technologies; and 16% from Appearance & Performance Technologies. Engelhard is also a major kaolin producer, with capacity for producing about 2.5 M tonnes/y of kaolin. A new kaolin grade has recently been launched for use in making decorative laminate papers, with the aim of partial TiO2 substitution. Engelhard is forecasting sales of $24 M/y for this kaolin grade by 2010. Both BASF and Engelhard are major players in the pigment sector. The acquisition of Engelhard will make BASF a world leader in catalysts. The world market for emissions catalysts should grow by at least 5%y. Focus on Pigments, Feb 2006, 1-2
Trimellitic anhydride capacity is surplus in China Global capacity for trimellitic anhydride (TMA) is about 250,000 tonne/y, with consumption put at about 170,000 tonne/y, shared between the US (22.5%), Western Europe (24.4%), Japan (18.8%), and other regions (34.3%). Almost 90% of TMA is used to produce trimellitate plasticizers and powder coatings. In China, TMA capacity rose to over 56,000 tonne/y in 2005. Consumption of trioctyl trimellitate plasticizers in China is expected to reach about 21,000 tonnes in 2006, with demand for TMA rising to about 9500 tonnes. Demand for powder 6

coatings in China in 2006 should reach about 200,000 tonnes, with polyester-epoxy resins blends accounting for about 150,000 tonnes and requiring about 7000 tonnes of TMA. Chinese demand for TMA in the manufacture of insulating coatings is expected to rise to about 1600 tonnes in 2006. Usage of TMA in China in curing agents, alkyd resins, and other sectors is expected to reach about 550 tonnes, 300 tonnes, and 200 tonnes, respectively, in 2006. With total TMA demand in China likely to be about 19,200 tonnes in 2006, a further increase in production capacity to over 65,000 tonne/y will result in a significant surplus.

NEW PRODUCTS New catalysts display photocatalytic functions without light Several Japan based companies have developed and/or introduced new varieties of catalysts that demonstrate antibacterial, deodorizing, antifouling and other photocatalytic features, even without light or ultraviolet rays. These include Fuji Kihan’s PIP Titan catalyst, designed principally to decompose and deodorize organic substances and chlorine products. The material is formulated by the rapid injection of titanium metal powder in the atmosphere, creating a thin titanium dioxide film on metal or hard ceramic surfaces. A research and development group led by Vision Development has come up with a charge-transfer catalyst in a suspension form consisting of diamond particles. The product not only exhibits deodorizing function, but has oxygen regulating properties as well. Nichirin Chemical has created a coating solution that breaks down hazardous
C O AT I N G S substances by reacting to oxygen and water in the air. Branded as Selfeel, the air-catalyst incorporates aluminium and iron mixed with titanium and potassium. Japan Chemical Week, 9 Mar 2006, 47 (2358), 2
Light enhanced biocides The Australian Research Council centre for functional nanomaterials is studying tiny particles of titanium dioxide currently used on outdoor surfaces such as self cleaning windows, to be used in indoor surfaces in homes and hospitals. The particles work by absorbing UV light that energises electrons, giving them an oxidising quality stronger than any commercial bleach. These nanoparticles then kill microbes and break down organic compounds. Surfaces coated with titanium dioxide have another property, superhydrophilicity, which means that no droplets can be formed and water runs straight off the surface, giving it a washing effect. Presently, titanium dioxide can only be activated by the UVA in sunlight. However, the Australian researchers are confident they will find a way to activate titanium dioxide using indoor light. Laboratory trials have shown that these new nanoparticles activated by lamplight were able to kill E-coli. For more information visit Website: http://www.arccfn.org.au
A new pigment range sets the standard for ultramarine blue Spanish company Nubiola Pigmentos SL in Barcelona recently launched Nubicoat, a range of ultramarine blue pigments for applications in powder coatings, liquid decorative coatings and metallic industrial coatings for cars, motorcycles, bicycles and mobile phones. The company has been developing the Nubicoat range for 4 years. Nubicoat HTS (high tinting strength) and Nubicoat HWR APRIL 2006
