Spezial Primer A-867

high performance primer for challenging applications increase adhesion of PUR and Epoxy coatings

Spezial Primer A-867 is a chemical coupler made to increase the adhesion of Epoxy coatings and Polyurethane coatings on tiles, stainless steel and mineral surfaces. Used as waterproofing, it avoids the bubble effect on humid surfaces. Compared with standard primers, which just glue on the subsequent coating, Spezial Primer A-867 reacts actively and creates a chemical bonding between surface-primer and coating.
