LOCTITE® SF 7649 is a solvent-based activator for surface preparation that provides for low temperature curing, i.e. when the application temperature is below 15°C. It is designed to promote the curing speed of LOCTITE® anaerobic adhesives and sealants without any significant loss of joint strength. Ideal for applications with passive metals or inert surfaces and with large bond gaps.

Qualities and Characteristics

• Increases cure speed on passive and inactive surfaces
• For large bond gaps
• For low-temperature curing (< 5°C)
