3M™ All Purpose Sealant Primer P591 is a black, one-part formulation that helps to improve adhesion of polyurethane and hybrid adhesive sealants. This versatile black primer is an Isocyanate- and solvent-based primer developed initially for acrylics, polycarbonate and polyester bonding applications. Meets FMVSS212 crash test standard.
Exceptional Performance on Acrylics, Polycarbonates and Polyester
As versatile as it is effective, 3M™ All Purpose Sealant Primer P591 works as well on substrates like metal, glass, plastics, wood and concrete as it does on acrylics, polycarbonate and polyester substrates. This primer is a low viscosity adhesion promoter (PDF, 45.91 Kb) designed for use with the 3M™ Polyurethane Adhesive Sealants 500-Series and 3M™ Silane Modified Polymer Adhesive Sealants 700-Series, as well as the 3M™ Polyurethane Glass Adhesive Sealant 590 with or without 3M™ Adhesion Promoter AP596.
3M™ All Purpose Sealant Primer P591 (PDF, 266.32 Kb) prepares surfaces to maximize bonding. Bonding and sealing keeps moisture out and supports structural integrity. For optimum performance, use with 3M™ Adhesive Sealants 550 and 590 on typical substrates like fiberglass, PVC, polycarbonate, aluminum, stainless steel, cold rolled steel and glass.
