Hardener is a medium-viscosity epoxy curing agent. It is used in a majority of
situations, at lower temperatures and to produce a rapid cure that develops its
physical properties quickly at room temperature.
with the 105 Resin in a five-part resin to one-part hardener ratio, the cured
resin/hardener mixture yields a rigid, high-strength, moisture-resistant solid
with excellent bonding and coating properties. Not intended for clear coating.
