Features and Benefits

Red, high strength, high viscosity methacrylate-based threadlocking adhesive, suited to large threads. Fluoresces to allow monitoring.
LOCTITE® 277 is a red, high strength, high viscosity, methacrylate-based threadlocking adhesive. It has a fixture time on steel of 30 min, brass 25 min and stainless steel 270 min making it deal for applications where migration of the adhesive must be prevented. Can tolerate slight contaminations of industrial oils. Suited to large threads. Fluoresces to allow monitoring.
