BC7062/BC7062-1 Casting Epoxy Systems
The BC7062 family of mass casting resins are aluminum filled, low viscosity epoxy. Without foaming or yielding excessive shrinkage, the BC7062-1 room-temperature cure system allows the user to choose thickness of 1/8 inch minimum to a maximum of 3/4 inches. Casting thicknesses may be increased by incorporating aluminum needles, puffs, or granules. BC 7062, when properly cured, provides nearly perfect reproduction, resulting in a hard, tough, dimensionally stable surface. It is used in constructing duplicate models, prototypes, patterns, facing dies, etc.
