Superior Adhesion

DesoGel® EAP-9 provides an effective, easy to apply alternative to traditional chromated conversion coatings. EAP-9 dries to a thin, clear, durable coating that provides protection to the metal and adhesion to the organic coating. It is a dry in place application method eliminates two concerns of chromated solutions: exposure to hexavalent chromium and production of large volumes of contaminated rinse water. EAP-9 has proven to virtually eliminate rivet rash and adhesion issues when used as recommended. EAP-9 is the recommended adhesion promoter for use under Desothane® CA 7700 series, CA 7502 and CA 7502E primers.
