TC-4485 A/B
IRON-FILLED EPOXY MASS CASTING SYSTEM
TC-4485 A/B is a room temperature curing, mass castable epoxy resin system that produces a tough, dense, low shrink solid
material with fine detail reproduction. TC-4485 A/B is designed for single-pour castings up to 3″ thick, or for thicker castings up
to 8″ using a stage pour procedure.
Slower reacting system designed for thicker casts Improved viscosity for easier pouring
