105 Epoxy Resin® is the base material on which all West System 105System epoxy compounds are built. The resin is a clear, pale yellow,low-viscosity liquid epoxy resin. Formulated for use with West Systemhardeners, it can be cured in a wide temperature range to form ahigh-strength solid with excellent moisture resistance.
105 Resin is formulated without volatile solvents and does not shrinkafter curing. It has a relatively high flash point and no strongsolvent odor, making it safer to work with than polyester or vinylesterresins. Resin viscosity is approximately 1000 centipoise (cp) at 72 F(22C),
105 Resin is designed specifically to wet out and bondwith wood fiber, fiberglass, reinforcing fabrics and a variety of metalswhen mixed at the proper ratio with a West System hardener. Anexcellent adhesive, 105 mixtures will bridge gaps and fill voids whenmodified with West System fillers and can be sanded and shaped whencured. With roller applications, it has excellent thin-filmcharacteristics to flow out and self-level without “fisheyeing.” 105Resin/207 Hardener mixtures cure clear so you can achieve a naturalfinish when coating with varnish.
