Used in a majority of situations, at lower temperatures to produce a rapid cure that develops its physical properties quickly at room temperature. Mixed with the 105 Resin in a five-part resin to one-part hardener ratio.
*Epoxy cures faster in warmer temperatures with thicker applications and slower in cooler temperatures with thinner applications.
105/205 Epoxy can be thickened with WEST SYSTEM fillers to bridge gaps and fill voids and can be sanded and shaped when cured. With roller applications, it has excellent thin film characteristics, allowing it to flow out and self-level without “fish-eyeing.” Multiple coats of 105/205 Epoxy create a superior moisture barrier and a tough, stable base for paints and varnishes. It is formulated without volatile solvents resulting in a very low VOC content. It has a relatively high flash point, no strong solvent odor and does not shrink after curing.
