Dri-Loc

Dri-Loc® adhesives (from Loctite Corporation), applied to threaded parts, form a unique coating that converts ordinary fasteners into self-locking fasteners.
Dry to the touch, Dri-Loc adhesives become an integral part of the fastener and stay inert until parts are used. During the assembly process, Dri-Loc adhesive is activated by assembly forces, releasing anaerobic adhesive which locks parts securely.
Dri-Loc adhesives are applied to the full circumference of the fastener. Resin fills all voids in the threads when installed, and cures to form an excellent seal to both liquids and gases. (For pre-applied non-locking thread sealant, see Vibra-Seal®)
Dri-Loc adhesives are designed for applications where specific shear strengths, temperature range and substrate types are necessary.
All Dri-Loc adhesives harden in the absence of air on ferrous and nonferrous metals without primer, activators or heat. They exhibit controlled lubricity, low on torque and are dry to touch for ease of assembly with automatic or hand tools.
