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 resin. 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.
designed specifically to wet out and bond with wood fiber, 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
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 odor, making it
safer to work with than polyesters. Resin viscosity is approximately 1000 cP
(centipoise) at 72°F (22°C).
