TC-1651 is an aluminum powder filled epoxy casting resin system that provides service temperatures in the range of 340°F (171°C). TC-1651 is most commonly used for the construction of molds that require good heat conductivity, outstanding durability, and that provide production run capability. TC-1651 is commonly combined with SC-125 Aluminum Granules for casting sections thicker than 3" (76mm) to decrease shrinkage and lower exotherm.
