LOCTITE SF 770 Polyolefin Primer 100ml

LOCTITE SF 770 is a specialist polyolefin primer designed to improve the bonding performance of LOCTITE instant adhesives on difficult-to-bond plastics. Developed for use on low surface energy materials such as polyethylene (PE), polypropylene (PP), PTFE and thermoplastic rubber, SF 770 significantly increases adhesion where conventional cyanoacrylate adhesives may struggle to achieve reliable bond strength.

Applied as a surface treatment prior to adhesive application, SF 770 promotes stronger, more durable bonds on challenging substrates without affecting adhesive cure speed. The primer is widely used in automotive, industrial, manufacturing, electronics and maintenance applications where bonding low surface energy plastics is required.

LOCTITE SF 770 is specifically formulated for use with LOCTITE cyanoacrylate instant adhesives and is suitable for both production and repair applications requiring improved adhesion performance.
