105 Epoxy Resin® is the base material on which all West System 105 System
epoxy 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.
105 Resin is formulated without volatile solvents and does not shrink after
curing. It has a relatively high flash point and no strong solvent odor, making
it safer to work with than polyester or vinylester resins. Resin viscosity is
approximately 1000 centipoise (cp) at 72 F (22C),
105 Resin is designed
specifically to wet out and bond with wood fiber, fiberglass, reinforcing
fabrics and a variety of metals when mixed at the proper ratio with a West
System hardener. An excellent adhesive, 105 mixtures 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 “fisheyeing.”
West System resin and hardeners are sold in matched sets according to the
letters A, B and C. An "A" Kit (resin plus hardener) is 1 quart, "B" is 1 Gallon
and "C" is 5 Gallon. Each part must be purchased seperately, however make sure
you order both parts (hardener and resin) in the same size A, B or C.
