ANAEROBIC ADHESIVES

ANAEROBIC adhesive/sealants are formulated for use in thread locking, sealing, fastening and retaining of metal components. This material is designed to eliminate the need for mechanical locking devices such as lock washers, set screws, lock nuts and cotter pins. Units assembled with this type of adhesive resists vibration and seals against corrosion, seizure, solvents, and other chemicals that might lead to a loose joint or assembly. Because anaerobics cure in the absence of air they harden in the spaces between the bolt threads or other tight fitting assemblies locking the parts in place.

SELECTION:

Anaerobics are manufactured by a number of companies the most common of which is Permabond. Adhesives are available in a number of different strengths and viscosities. Selection is based on the type of assembly - be it small screws that need to be removed for maintenance, or locking a bearing on a shaft, or holding a bolt on a high strength assembly of a vehicle. Refer to the manufacturer's catalog as a guide to selection.

USAGE:

Mating surfaces must be clean and dry before applying the adhesive. Very little is needed so use sparingly. Torque the assembly immediately after application before adhesive begins to cure. Thread lockers may be used in temperatures from -65ºF to 300ºF and resist most automotive fluids and common solvents. Anaerobics are formulated primarily for use on metals, other type of thread lockers are available for plastics and other materials.
