Loctite SF 770 300 g primer for surface preparation prior to bonding with cyanoacrylate adhesives, for difficult-to-bond plastics PE, PP, PTFE Teflon and silicone rubber
Description
Application Loctite 770
Polyolefin Primer LOCTITE® 770 is a one component product which dries very quickly at room temperature. It is used to prepare polyolefins and other materials with low surface tension for bonding with Loctite cyanoacrylate adhesives. On such prepared surfaces, cured Loctite cyanoacrylates retain the same properties as described in the TDS for the relevant adhesive, except in some cases noted here.
Polypropylene, polyethylene, PTFE, and thermoplastic rubber are generally difficult to bond. However, when primed with Loctite 770 Polyolefin Primer, adhesion of Loctite cyanoacrylate adhesives can be achieved. Loctite 770 Polyolefin Primer is only recommended for difficult-to-bond surfaces.
