Retaining
Choosing a retaining compound
Retaining compounds are typically used to join non-
threaded cylindrical assemblies made of some sort of
metal. Metals can be designated as active or inactive.
Active metals (carbon steel, copper, or bronze) will
typically corrode faster than inactive metals (stainless
steel, plated parts, or anodized aluminum). When
working with inactive metals, it is generally
recommended that a primer be used to increase the
cure speed of the retaining compound.
New Loctite® retaining compounds have historically been
formulated as liquids due to their reactivity to ensure
they remain stable and ready to use. Recent
breakthroughs have led to the development of a stable,
semisolid stick formulation. This has opened the door to
applications where the liquids were considered too messy
or inconvenient. This new semisolid formulation allows
direct contact of the compound to the part. This ensures
not only that the product is placed exactly where it is
needed, but also that it stays there as the cylindrical
assembly is positioned and assembled.
The following are key factors to consider when
choosing a retaining compound.
1. Gap Size Between Parts – Typically, low viscosity
2. Temperature Resistance – Most Loctite® retaining
3. Bond Strength – In applications that require a
4. Cure Speed – Many production applications require

specific testing. It is recommended that you conduct on-part
testing to ensure product performance before specifying any
retaining compounds.

retaining compounds with fast cure speed in order to
maximize production rate. On the other hand, some
applications require a slower cure so that adjustments
can be made after the parts have been assembled. Our
range of Loctite® retaining compounds offers varying
rates of cure enabling you to choose the one that best
matches your application.
retaining compounds (125 to 2000 cps) are used for
gaps up to 0.010". For gaps greater than 0.010",
retaining compounds with higher viscosities
(>2000 cps) should be used.
compounds are made to withstand temperatures
up to 300°F. For those applications that require
resistance greater than 300°F, Henkel offers a line
of high temperature resistant Loctite® retaining
compounds that can withstand temperatures
up to 450°F.
permanent bond, a high strength retaining
compound is recommended. If at some point in the
future, parts will need to be taken apart for service, it
is better to use a low or medium strength product.
