3M™ Adhesion Promoter AC-132

3M™ Adhesion Promoter AC-132 is formulated as a solvent-based adhesion promoter for bonding polysulfide and polythioether sealants to metal and/or solvent resistant coatings. It contains mixed solvents blended with a surface activator agent, which helps reduce time to adhesion, and helps sealant adhere to difficult-to-bond surfaces.

3M™ Adhesion Promoter AC-132 may be applied to clean surfaces with gauze or a brush prior to application of polysulfide or polythioether sealants to metal and/or solvent resistant coatings. It allows for faster initial adhesion build rate of polysulfide and polythioether sealants to help reduce your process time. The one component formula needs no mixing to provide easy application.
