WebThe refractory coating for lost foam casting is finally applied to the surface of the foam model. Different types of foams and different casting materials have different requirements for coating properties. In addition, the foam is not gas permeable, the heat distortion temperature is low (about 70 °C), the affinity for water is small, and the ... WebDescription ITC-100 HT Ceramic Coating is a versatile high temperature coating that has proven to achieve outstanding energy savings and refractory protection. Use it alone or as a base coat for other ITC products. It is used as a covering for ceramic fiber insulation or castable refractory.
