Epocast_1625-A/B Core Reinforcing Compound
Epocast 1625-A/B is a high performance core reinforcing compound. This aluminum filled, high viscosity system exhibits outstanding compressive strength and resistance to deformation under load at temperatures up to 350°F. It can be extruded to fill honeycomb core for reinforcement in panels used in areas where high temperatures are encountered.
