LOCTITE® 675 is a green, very low viscosity, high strength, slow curing methacrylate retaining compound ideal for close fitting press fit and loose fitting slip fit applications.
Fixture time on steel is 45 min. Maximum diametrical clearance is 0.1 mm and service temperature -55 to + 150ºC.
TYPICAL APPLICATIONS
- Locks bearings on shafts and in housings.
- Bonds sleeves, wear rings and bushings in place.
- Augments press fits.
- Bonds pivot pins, adapters and plugs in place.
- Seals mechanical fits that have small clearances.
Directions for Use
For best performance, surfaces should be clean and free of grease. Ensure joint is completely filled with adhesive. For slip fitted assemblies, this is achieved by applying adhesive around the pin and threading edge of the collar and using a rotating motion during assembly to ensure good coverage. For press fitted assemblies, the adhesive should be coated onto the pin. The collar should then be heated to create sufficient clearance for free assembly. Parts should not be disturbed until sufficient handling strength is achieved. This grade will develop temperature resistance after exposure to a heat cure of one hour at 180ºC or longer times at temperatures above 120ºC in service.
