- Compatible with polysulfide and polythioether sealants
- Works well on metal and solvent resistant coatings
- One-part Formula optimized for easy application
- Allows for faster initial adhesion build rate of sealants to substrate
We formulated 3M™ Adhesion Promoter AC-132 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.
AC-132 promotes faster initial adhesion build rate of polysulfide sealant used on various substrates
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. AC-132 allows for faster initial adhesion build rate of polysulfide and polythioether sealants to help reduce your process time. Our one component formula needs no mixing to provide easy application.
