Product Description
Eastman™ Adhesion Promoter 550-1 is Eastman’s second-generation nonchlorinated product for adhesion to TPO and PP. 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.

Due to its lack of chlorine and to its chemical structure, Eastman™ Adhesion Promoter 550-1 exhibits excellent gasoline resistance. Formulators should be able to get a boost in gasoline resistance performance by adding AP 550-1 to their current adhesion promoter system.

Eastman™ Adhesion Promoter 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.
