LOCTITE SF 770 Primer for Hard-to-Bond Surfaces Bottle 10gr

LOCTITE SF 770 is a professional primer designed to improve the adhesion of instant adhesives on hard-to-bond surfaces. It is the ideal solution when working with low surface energy materials such as polyethylene (PE), polypropylene (PP), PTFE and thermoplastic rubbers, which normally do not allow effective bonding with adhesives alone.
Applied before the instant adhesive, it provides faster, more secure and longer-lasting adhesion, drastically reducing issues with bond failure. Its low-viscosity formulation ensures easy application and very fast drying, making the product suitable for both professional use and precision technical work.

Main benefits:
– Significantly improves the adhesion of instant adhesives
– Ideal for low surface energy substrates
– Enables reliable bonds on difficult materials
– Quick and easy application
– Reduces errors and rework in bonding operations
– Suitable for professional and advanced private use

Recommended applications:
– Preparation of hard-to-bond plastic surfaces
– Bonding on PE, PP, PTFE and thermoplastic rubbers
– Technical and industrial assemblies
– Quick repairs with instant adhesives
– Craft and advanced DIY applications

Thoroughly clean surfaces of dust, grease, and contaminants. Apply LOCTITE SF 770 to the area to be bonded and let it dry for a few seconds. Then apply the instant adhesive and proceed to join the parts. The product is a very low viscosity liquid, specifically for use with cyanoacrylate adhesives, and is fluorescent under UV light to allow visual inspection of the application.
