West System® 105 Epoxy Resin

Use with West System Fast Hardener 205: 

105 Epoxy Resin®, the base material on which all West System 105 System epoxy compounds are built, is a clear, pale yellow, low-viscosity liquid. 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. 

Formulated without volatile solvents. Does not shrink after curing. 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 hardener. 

An excellent adhesive, 105 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 Resin/207 Hardener mixtures cure clear so you can achieve a natural finish when coating with varnish.
