The Loctite SF 770 Primer is a specially formulated adhesive designed for the pre-treatment of difficult-to-bond plastics such as polyethylene, polypropylene, and polytetrafluoroethylene (PTFE). This primer enhances the adhesion of Loctite instant adhesives on materials with low surface energy. It is particularly useful in applications where conventional adhesives struggle to create a durable bond. The primer comes in a convenient brush bottle that allows for targeted and clean application. It is important to note that the Loctite SF 770 is not recommended for connections that require high peel strength. Using this primer ensures the functional properties of the subsequent adhesive application in the cured state.

• Improves adhesion on polyolefins and other low surface energy materials
• Suitable for difficult-to-bond materials such as PTFE and thermoplastic elastomers
• Convenient brush bottle for targeted application
• Not recommended for applications with high peel strength requirements.
