105 Resin is the base material of the West System family of products. It is used with all of the West System 200 Series hardeners.
105 Resin is a clear, low-viscosity liquid, epoxy resin. It can be cured in a wide temperature range to form a high-strength solid with excellent moisture resistance. It is designed specifically to wet out and bond with wood fiber, fiberglass, reinforcing fabrics and a variety of metals.
105 Resin will fill gaps and bridge voids when modified with West System fillers and can be sanded and shaped when cured. With roller applications, it possesses thin-film characteristics to flow out and self-level with out "fish-eyeing". Resin viscosity is approximately 1000 cps at 72°F.
NOTE: West System resins and hardeners are each available in 4 sizes, and for each size of resin, there is a corresponding size container of hardener.
To ensure a correct match, be sure all containers are labeled with the same "group size" letter (A, B, C, or E). This letter can be found at the end of each part number on the can.
