Introduction to anaerobic adhesives and sealants.
Anaerobic adhesives and sealants were developed by the founder of the Loctite Corporation, now the
Henkel Corporation, in 1953 and, since then, they have significantly evolved to meet the highest
requirements of vehicle manufacturers and vehicle maintenance and repair.
Anaerobic adhesives and sealants are resins that convert from liquid to a tough structural solid in the
absence of air and the presence of metal.
The primary functions of anaerobic resins are:
Threadlocking Thread Sealing Gasketing Retaining
Each one of these functions is based upon control of five major variables: strength, viscosity, adhesion,
flexibility and temperature resistance. These five parameters give anaerobic users considerable latitude in
adjusting properties for optimum performance in specific application areas.
Another variable that should be considered is the surface on which the adhesive will be applied.
For certain surfaces or other special requirements, the use of a primer is recommended.
Why use a primer?
1. Primers activate inactive surfaces.
2. Primers speed cure times for faster return to service.
3. Primers speed curing through larger gaps and deep threads.
4. Primers substantially speed cure times on cold parts.
5. Primers act as cleaning agents.
Active surfaces (Primer optional): Brass, copper, bronze, iron, soft steel, nickel.
Inactive surfaces (Primer required):
Aluminum, stainless steel, magnesium, zinc, black oxide,
cadmium, titanium, others.
