Surface Preparation - activator. Solvent-based. Low temperature curing.
LOCTITE SF 7649 is designed to promote the curing speed of LOCTITE anaerobic adhesives and sealants without any significant loss of joint strength. It is especially recommended for applications with passive metals or inert surfaces and with large bond gaps. LOCTITE SF 7649 is particularly recommended when the application temperature is below 15 °C.
- Increases cure speed on passive and inactive surfaces
- For large bond gaps
- For low-temperature curing (< 5°C)
