WEST System 105 Epoxy Resin

WEST System Epoxy cures to a high-strength plastic solid at room temperatures, by mixing specific proportions of liquid epoxy resin and hardener.

This clear, pale yellow, low-viscosity liquid epoxy resin is 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.

Designed specifically to wet out and bond with wood fiber, fiberglass, reinforcing fabrics and a variety of metals, 105 is an excellent adhesive that will bridge gaps and fill voids when modified with WEST SYSTEM fillers. It can be sanded and shaped when cured. In roller applications, it has excellent thin-film characteristics to flow out and self-level without fisheyeing. 105 resin has a relatively high flash point and no strong solvent odor, making it safer to work with than polyesters.

By using a simple "cookbook" approach you can tailor the handling characteristics and the physical properties of the cured epoxy to suit your working conditions and specific coating or bonding application.

1. Start with 105 Resin, the basic ingredient of all WEST SYSTEM epoxy compounds.

2. Mix with one of four WEST SYSTEM Hardeners. Select a hardener for its intended use and for the cure speed best suited for your job in the temperature range in which you are working.

3. Add one of six WEST SYSTEM fillers to thicken the mixture as needed. Select a filler for its handling characteristics or cured physical properties. Or, add one of six WEST SYSTEM additives to provide specific coating properties.

Just what I needed.

5

Local hobby shop was out of the item and unknown as to when they would get it in. Needed product to continue building my radio control B-17 bomber. Use it with the 207 hardener to apply thin fiber glass to the balsa covering to seal and strengthen the covering in preparation for painting.

Have always used this product and don't like to take chances . . . I know how to use it and it always works but must to care re. ambient temps. That said, have had a some Totalboat epoxy and hardeners that will likely try them out on a few smaller projects over in the next few months.

Performance deserves 5 stars. Storage can be a problem.

For a occassional user who tries to store resin for say 12 months .. it gets cloudy, makes you wonder.

Used on a kayak I am building from cedar strips. Coupled with 4oz fiberglass on exterior and 6oz fiberglass on interior provides a very solid hull.

Very difficult to use

1

I've used several different manufactures of epoxies. West System has always been the most difficult to handle and to achieve the results I'm looking for. Always bubbles, leaves to much blush, and never seems to cure correctly. Best I've found and with best results was ProBuild by Adtech. Always comes out right and is never frustrating to use.
