Thermally Conductive

RBC Industries' line of thermally conductive epoxy resins includes some of the most advanced epoxy systems available today. Our standard line offers products that can be cured at room temperature or at elevated temperatures or we can custom formulate to meet any specific project need. Of course the key to our thermally conductive materials is the fact that each of these epoxy systems provide excellent electrical insulation, prevent heat distortion and offer low shrinkage. Whether you need a material to be used as an adhesive, as a heat sink for large castings or as an encapsulant for heat generating components, RBC Industries offers the premiere line of thermal management resins.

Over the past thirty-seven years RBC has formulated some of the world's finest thermally conductive epoxies for potting and encaspulating. With your technology on the line it would be unthinkable to use a material that you cannot trust. From the smallest pieces to the largest ballasts, when thermal management is a priority, RBC is the name that the electronics, electrical, automotive and aerospace industries trust to protect, insulate or simply hide their most precious components.
