Product Description
Eastman Adhesion Promoter 550-1 is a nonchlorinated product for adhesion to TPO and polypropelene-based substrates. Nonchlorinated systems are known to demonstrate excellent performance under 2-part urethane (2K) coatings, but often their application is limited to 2Ks. AP 550-1 expands nonchlorinated performance to applications under many melamine-cured systems. Formulators should be able to get a boost in gasoline resistance performance by adding AP 550-1 to their current adhesion promoter system. Due to its lack of chlorine and its chemical structure, Eastman Adhesion Promoter 550-1 exhibits excellent humidity and gasoline resistance, particularly under 1K systems. Eastman Adhesion Promoter AP 550-1 is available at 25% weight solids in aromatic 100 or in xylene. If the solution gels due to storage at low temperatures, it can be re-liquefied by warming with agitation.
