Loctite SF 770

Designed to optimize difficult-to-bond and low-surface-energy substrates, this specialized primer prepares hard-to-wet engineering plastics for reliable adhesion with instant adhesives. It is exceptionally well-suited for preparing thermoplastic rubbers, polyethylene (PE), polypropylene (PP), and polytetrafluoroethylene (PTFE) prior to assembly. Contains a UV-fluorescent tracer to facilitate automated inspection and quality control verification.

Key Performance Specifications

Functionality: Surface preparation treatment to enhance bondability on low-energy substrates.

Target Materials: Specialized compatibility for notoriously difficult plastics, including polyethylene, polypropylene, PTFE, and thermoplastic elastomers.

Compatibility: Engineered specifically to work in tandem with industrial-grade instant adhesives.
