West System 105 Epoxy Resin


Shelf life: If the containers are kept sealed when not in use
WEST SYSTEM resins and hardeners should remain usable
for many years. Over time, 105 Resin will thicken slightly and
will therefore require extra care when mixing. Hardeners may
darken with age, but physical properties are not affected by colour.
Mini Pumps may be left in containers during storage. It is a
good idea, after a long storage, to verify the metering accuracy of
the pumps and mix a test batch to assure proper curing before
applying epoxy to your project.

Low Temperature Considerations: When using WEST SYSTEM
Epoxy at low temperatures, special precautions should be taken
to assure maximum performance. For detailed information on working
with epoxy at low temperatures, refer to pamphlet #002-915 Cold
Temperature Bonding and Coating with Epoxy.

West System 105 EPOXY RESIN
105 Resin is the base material of the WEST SYSTEM family of products,
on which all of the WEST SYSTEM compounds are built. The resin is a clear,
pale yellow, low-viscosity liquid epoxy. Formulated for use with WEST SYSTEM
hardeners, it can be cured in a wide temperature range to form a high strength
solid with excellent moisture resistance. It is designed specifically to wet out
and bond with wood fibre, fiberglass, reinforcing fabrics, and a variety of metals.
 An excellent adhesive, 105 will bridge gaps and fill voids when modified with
WEST SYSTEM fillers and can be sanded and shaped when cured.  With roller
applications, it has excellent thin-film characteristics to flow out and self-level without
"fish eyeing". The resin cures clear so that you can achieve a natural finish when
coating with varnish. It has a relatively high flash point and no strong solvent odour,
making it safer to work with than polyesters.
Resin viscosity is approximately 1000 cps at 72°F (22°C).
