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

105 Resin is formulated without volatile solvents and does not shrink after curing. It has a relatively high flash point and no strong solvent odour making it safer to work with than polyester or vinylester resins. Resin viscosity is approximately 1000 centipoise (cp) at 72 F (22C)

105 Resin is designed specifically to wet out and bond with wood fibre fibreglass 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 "fish eyeing." 105 Resin/207 Hardener mixtures cure with excellent clarity so you can achieve a natural wood grain finish when coating with varnish.
