High Temperature Potting & Casting Materials

Aremco offers an expansive range of ceramic-based materials used for the assembly of high temperature, high power electrical devices, and 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 as one- or two-part systems. One-part systems are mixed with water or a specialty binder used to improve moisture resistance. Two-part systems consist of a powder and liquid binder system. Materials set at room temperature in several hours, then cured at ~250 °F in 2-4 hours.

Sil-Bond™, a silicone-ceramic potting compound for optimal moisture resistance, is now offered along with EZ-Cast™ for producing silicone rubber molds.
