A Non-HAP (Hazardous Air Pollutant) Coating for Extruded Aluminum

Donald J. Algrim, Ph.D., Tracy Jean Rajala, and David E. Lindow, BASF Corporation, Michigan, USA


ABSTRACT --- BASF has developed a coating composition using a nonhazardous
air pollutant (HAP) solvent blend. This new technology eliminates the
use of solvents that are known or suspected to cause serious health effects—such
as cancer, reproductive effects, or birth defects—or adverse environmental
effects. This new product replaces a product line that used five hazardous air
pollutants, amounting to 8 to 10 percent of the product as delivered. The use of
xylene, diethylene glycol ethers, and several other materials was eliminated. The
new product provides improved application efficiency and quality, and is
economical in a highly competitive market. At market projections, this product
will reduce emissions of hazardous air pollutants by about five hundred thousand
pounds annually.
