In December 2004, the U.S. EPA granted Lyondell Chemical Company's 1997 petition to add TBAC to the list of VOC-exempt compounds.1 This action ended an eight-year process during which the company was asked to demonstrate that TBAC not only had negligible photochemical reactivity, the official requirement for exemption, but that it also had low toxicity and was not likely to have other adverse environmental impacts.
Color is an ever-present measure of quality, even in a subliminal sense. Whether it be automobiles, food, appliances, toys, etc. we perceive quality by the color of the product and how well the colors cover and match. If an automobile is repaired after an accident, do we first judge the quality of the repair job by the structure of the new part or its metal composition, or do we judge it by how well the color of the fender was matched to the door and hood? Unless the fit is horrible, the vast majority of people will judge the color first.
Series 22 colorant formulation from Ferro Corporation is said to prevent float and flocculation of pigments, increasing uniformity of coloration achieved using "4800 Epoxy Colorseal" from Versatile Building Products. Versatile Building Products Inc. (VBP) manufactures treatment and repair products for cement, concrete and stone floors. These range from epoxy and polyurethane coating systems for commercial and residential applications to stains, sealers, mortar and substrate repair materials.
Biphor is a new family of aluminum phosphates or polyphosphates made by a patented wet chemistry process.8 It is a "green chemistry," zero-effluent product made under mild temperature and pressure conditions that do not create any environmental problems during the fabrication process. Due to its chemical nature, BIPHOR residues in the paint industry or in the final user location may be safely discarded in the environment as a fertilizer component.
Arkema Inc., a global performance products company, recently received an R&D 100 Award1 for new technology that offers important advancements for the self-polishing marine antifoulant paint technology industry, including significant environmental and economic benefits over the options currently available. The technology controls the self-polishing behavior of marine antifoulant paints, preventing organism growth on the hulls of sea¬going ships. The technology should ultimately have a major impact in terms of time and money saved for companies in the shipping industry.
The objective of this paper is to evaluate selected hydroxyl functional mono metha¬crylates, as well as reactive surfactants in emulsion polymerization (EP). Some of the selected hydroxyl functional monomers are extensively used as reactive diluents for radiation-curable adhesives and coatings. They are also used as capping agents in urethane methacrylate oligomers for the production of photopolymer printing plates and dry film resists.
