Both the resin and hardener are nearly colorless and are used in an easy 2:1 volumetric ratio. SilverTip Epoxy cures to a brilliant blush-free film with either the fast or slow hardener eliminating secondary bonding concerns as experienced with other epoxies. The working time is longer than most boat building epoxies without extending cure time. The cured film is tough and resilient with better heat resistance than other epoxies cured at room temperature. Fillers, wood flour, and bulking agents can be combined with SilverTip Epoxy, however, we suggest using the other members of the SilverTip series for adhesive, filleting and fairing applications.
