WHY USE A PRIMER?
. Primers activate inactive surfaces which are not required
with primerless products.
. Primers speed cure times for faster return to service.
. Primers speed curing through larger gaps and deep threads.
. Primers substantially speed cure times on cold parts.
. Primers act as cleaning agents.
Active surfaces (primer is optional): Brass, copper, bronze, iron, soft steel, nickel.
Inactive surfaces (primer is required): Pure Aluminum, stainless steel,
magnesium, zinc, black oxide, cadmium, titanium, others.

INTRODUCTION
Anaerobic adhesives and sealants were developed by the founder of
LOCTITE Corporation, now Henkel Corporation, in  and, since then, they
have significantly evolved to meet the highest requirements of equipment
manufacturers, maintenance and overhaul.
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:
Each one of these functions is based upon control of five major variables: strength,
viscosity, adhesion, flexibility and temperature resistance. These five parameters
give anaerobics users considerable latitude in adjusting properties for optimum
performance in specific application areas.
Another variable that should be considered is the substrate in which the adhesive
will be applied. For certain substrates or other special requirements, the use of
primer is recommended.
