LOCTITE SF 770 Primer – Surface Preparation for Polyolefins & Low Surface Energy Plastics (2024)

LOCTITE SF 770 Primer – Surface Preparation for Low Surface Energy Plastics

LOCTITE SF 770 is a professional-grade surface preparation primer designed to improve the bonding performance of LOCTITE instant adhesives on polyolefins and other low surface energy materials.

This primer enables reliable adhesion on materials that are typically difficult to bond, ensuring optimal curing and functional performance of LOCTITE cyanoacrylate adhesives.

Main Performance and Structural Features

• Specialized primer for difficult-to-bond plastics

Improves adhesion on polyethylene (PE), polypropylene (PP), PTFE and thermoplastic elastomers.

• Designed for use with LOCTITE instant adhesives

Ensures proper curing and full functional performance when surfaces are pretreated.

• Optimized for low surface energy materials

Specifically developed for substrates that standard adhesives struggle to bond.

• Fast and efficient surface activation

Enhances bonding strength without complex surface preparation processes.

• Industrial-grade formulation

Suitable for professional manufacturing and assembly environments.

• Controlled application

Recommended only for materials that are difficult to bond.
