LOCTITE® SF 770 is a surface primer designed to enhance the adhesion of cyanoacrylate adhesives on low-energy surfaces such as polyethylene, polypropylene, PTFE, and thermoplastic rubber. It is a transparent to slightly hazy liquid with very low viscosity and contains isopropyl acetate as a solvent. The primer improves bonding performance but is not recommended for applications requiring high peel strength.
