Surface Preparation
Henkel has a complete line of Loctite® surface
preparation accelerators, activators and primers, as well
as a complete line of general-purpose Loctite® branded
cleaners and degreasers, and specialized products to
ensure the maximum performance of Loctite® adhesives
and sealants.
Loctite® accelerators are used to increase the cure speed
and gap -filling capabilities of cyanoacrylate adhesives.
Activators are specially engineered curing agents for
structural adhesives. Loctite® primers are used to ensure
cure on inactive surfaces and speed the cure of
machinery adhesives.
Loctite® cleaners and degreasers are highly effective
and are available in both aqueous and solvent-based
formulations. When choosing a cleaner or degreaser,
the major factors to consider are dry time, residue, odor,
and substrate compatibility. Residue is a particularly
important concern because if there is any secondary
processing of the part, e.g., painting or bonding, a
residue could interfere with that process. Substrate
compatibility is a common concern when dealing with
plastics and solvent-based cleaners. The following chart
will help you to select the appropriate cleaner for your
application.
This chart should not be used to specify products without specific
testing. It is recommended that you conduct on-part testing to
ensure product performance before specifying a certain type of
surface preparation product.
Loctite® Adhesives and Sealants Product Specialists are available to
assist you with new product designs, or to help you re- engineer an
existing application for improved performance and cost savings.
They can also set up testing of your parts at the Henkel Customer
Engineering Center. For application assistance, call 1-800-LOCTITE
