West System 105 Epoxy Resin

Select Size:
Quart Gallon 5-Gallon

Overview

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 that cures to a hard, solid plastic with superior physical properties. 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 Epoxy 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 Epoxy 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 Epoxy hardener. An excellent adhesive, 105 epoxy 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.” 105 Epoxy Resin/207 Special Clear Hardener mixtures cure clear so you can achieve a natural finish when coating with varnish.

Formulated without volatile solvents, 105 Epoxy Resin 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 vinyl ester resins.

Pair 105 Epoxy with corresponding letter size of 205 Fast Hardener, 206 Slow Hardener, 209 Extra Slow Hardener or 207 Special Clear Hardener. This is resin only.

I’m using this for marine use. Pricey stuff, but for boats or planes, you don’t want to take chances. West system has been around forever and is a top product.
