LOCTITE 661 is an amber, anaerobic low viscosity, high strength adhesive that also cures in the presence of UV light. It’s therefore ideal for applications where any migration of the adhesive from the joint must be prevented. Fixture time on steel is 4 minutes and maximum diametrical clearance is >.15mm. Service temperature is -55◦C to 175◦C.
Strengths
single product, requires no mixing
dual cure, anaerobic and UV light
high strength
low viscosity, small gap filling
Applications
Retaining compound, high strength, low viscosity methacrylate anerobic adhesive that is also cured by UV light to prevent migration from the joint.
