High Temperature Potting and Casting Materials

Tech Bulletin A4

Aremco offers the most expansive range of ceramic-based materials used for the assembly of high temperature, high power electrical devices as well as high temperature fixtures, molds and tooling. These materials, based on aluminum oxide, aluminum nitride, magnesium oxide, silicon dioxide, silicon carbide, zirconium oxide, and zirconium silicate, offer unique properties with respect to operating temperature, thermal conductivity, dielectric and mechanical strength.

Ceramacast™ products are supplied in either one- or two-part systems. One-part systems are typically mixed with water or a specialty binder system that is used to improve moisture resistance. Materials set at room temperature in several hours, then cure at ~250 °F in 2-4 hours to provide optimal electrical and mechanical properties. Two-part systems have varying set times and are similiarly cured at 250 °F in 1-2 hours.
