UV-curable Refinish primer, Nonvolatile Coalescent Win

August 16, 2005

The U.S. EPA has presented Presidential Green Chemistry Challenge Awards to a UV-curable refinish primer from BASF Coatings and a coalescent from ADM.
BASF’s primer cures in just a few minutes when exposed to visible or near UV light from UV-A lamps, or even sunlight, according to the company. Compared to conventional products, the primer requires fewer preparation steps, is more durable, provides better corrosion protection and has an unlimited shelf life, BASF said. The new primer also contains 1.7 pounds of VOC per gallon versus 3.5-4.8 pounds per gallon for conventional primers.
ADM was honored for its Archer RCTM nonvolatile, reactive coalescent for latex paint. Archer RCTM is comprised of propylene glycol monoesters of sunflower oil fatty acids (approximately 66% linoleic acid). Instead of evaporating into air, the unsaturated fatty acid component of Archer RCTM oxidizes and crosslinks into the coating.
EPA has presented the Presidential Green Chemistry Challenge awards annually since 1996 to recognize discovery of innovative ways to use chemistry to significantly reduce pollution at its source. Nominations for the awards are judged by an independent panel of technical experts convened by the American Chemical Society.
