EP5351 Rigid, Silica-Filled, Hard, Fast Set Casting Epoxy

GENERAL DESCRIPTION: EP5351 is a rigid, filled system that has a fast gel time and cures at room temperature. It can be cast up to ¾" thick. EP5351 has less shrinkage than unfilled systems and better thermal dissipation properties and an extremely low moisture absorption. The medium viscosity allows for good impregnation.

APPLICATIONS: Casting of abrasion-resistant fixtures and nests for machining; electrical potting; anchoring bolts into concrete floors; leveling rough floors for machinery installation; inexpesnive alternative of tool steel for sizing gauges; production of surface plates.
