105 Epoxy Resin is the base for all West System epoxy resin compounds. It features a low viscosity that will cure to a pale yellow hard solid plastic with exceptional properties. Designed for use with the brand’s hardeners, West System 105 Epoxy Resin cures in a broad temperature range and offers superior moisture resistance. Formulated with low volatile solvents, 105 Epoxy Resin will not shrink after curing and has no strong solvent odor. This product was specifically designed for use on wood fiber, fiberglass, reinforcing fabrics, and metals. 105 Epoxy Resin fills voids and bridges gaps and may be sanded smooth after curing. Using a roller will highlight West System Epoxy Resin’s thin film characteristics and allow the finish to self-level without causing ‘fish-eyeing’.
NOTE: Pair West System 105 Epoxy with corresponding letter size on hardener.
Example: 105-A Epoxy Resin Quart requires 205-A Fast Hardener .44 Pint. 5 Parts Resin to 1 Part Hardener
*Epoxy cures faster in warmer temperatures and in thicker applications. Epoxy cures slower in cooler temperatures and in thinner applications. All times are estimates.
Each WEST SYSTEM Epoxy hardener has an ideal temperature cure range. At any given temperature, each epoxy resin/hardener combination will go through the same cure stages but at different rates of speed. Base your hardener selection on the amount of working time you’ll need for the job you’ll be doing at the temperature conditions you’ll be working under. The hardener selection guide and epoxy hardener container labels describe hardener pot lives and cure times.
The data we provide pot life is based on 100 grams or 4 pump strokes each of resin and hardener using our 300 mini pumps. If you are using a larger amount of epoxy or a different size of mixing pot the length of pot life can vary. To increase the pot life of a cup of mixed epoxy, spread it over a larger surface area, work in a cooler environment, or mix multiple, smaller batches as you go.
