Is there an alternative to chlorinated polyolefin adhesion promoters?
 
Eastman has developed a nonchlorinated adhesion promoter for PP and TPO, Eastman AP 550-1 (25% in xylene). Eastman AP 550-1 provides excellent adhesion when used under 1K/2K, 2K/2K, and 1K/1K basecoat/clearcoat paint systems. In addition, Eastman AP 550-1 exhibits excellent gasoline resistance when topcoated with a variety of paint systems.
