Primers & Activators

Surface Preparation - activator. Solvent-free. Low temperature curing.

LOCTITE® SF 7240 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. The product should also be used where the cure temperature is low. It is particularly recommended for cure conditions below 15°C.


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