Cotronics^® Durapot^® ceramics are high temperature, high resistance encapsulating and embedding cements that can be used for applications up to 1850°C.


These new high purity materials can be used on electrical and electronic equipment. Composed of alumina, magnesia (magnesium oxide) or zircon (zirconium silicate), and specially prepared for moulding, they provide an optimal solution to the problems of moulding at high temperature, exceeding the performance of epoxy resins and silicone. They harden at room temperature and hardening can be accelerated by light heating. Resistance to chemicals and solvents is excellent. Encapsulations are intended to protect and isolate circuits and components. The Durapot® range is designed to meet a variety of thermal, physical and electrical requirements. A comparison table groups their main characteristics.
