PRODUCT DESCRIPTION

West System 105 Epoxy Resin

105 Epoxy Resin is the base for all West System compounds. Featuring low viscosity that cures in a pale yellow hard solid plastic with superior properties. Meant to be used with West System hardeners, the 105 Epoxy Resin can cure in a wide range of temperatures and boasts supreme moisture resistance. Formulated with low volatile solvents the 105 Epoxy Resin does not shrink after curing and has no strong solvent odor associated with it. Specifically designed to work with wood fiber, fiberglass, reinforcing fabrics, and metals. Fills voids and bridges gaps and can be sanded and smoothed after curing. Using a roller showcases the 105 Epoxy Resin thin film characteristics and self level without fisheyeing. 

Product Features:

  • Viscosity: 1000 Centipose at 72° F
  • Thin Film
  • Self levels
  • Can be used on: Wood fiber, Fiberglass, reinforcing fabrics, and a variety of metals
  • Doesn't shrink after curing
  • Volatile solvent free making it safer to work with than polyester or vinyl resins

*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.
