BC 6128 is a black, non-staining, silicon carbide filled, "die surface" surfacing resin. This thixotropic resin system provides excellent surface duplication along with good vertical coverage. Extended mold life due to superior wear resistance and hardness are the major benefits derived from its use. This heat resistant system may be used at room temperature without post-curing. For use above 150°F a post-cure is required. Post cure for applications requiring temperatures above 250°F can be accomplished in an oven or in use by a gradual heat rise; 2 hours @ 150°F, plus 2 hours @ 250°F, plus 2 hours at 300°F. BC 6128 can afford consistent use to 300°F if required. Does not contain VCHD or MDA. Typical uses include constructing vacuum form tools, Injection and compression molds, RTM and RIM molds, and matched dies.
