Cotronics® products available in six refractory compositions: Alumina, Ceramic Foam, Silica, Silicon Carbide and Zirconia.

Cotronics® castable cement

Parts as small as an inch to parts measuring over 6 ft. in length, and over 2000 pounds in weight, are easy to make.

Just mix and pour into any non-absorbent mold and let harden overnight to produce highly detailed ceramics, usable to 2200ºC.

Now an unlimited number of high temp. problems can be solved with ceramics using an in house process.

RTC-70-1 two-component mouldable ceramic powder

RTC-70  fine is a  pure alumina  based powder Al2O3. It can withstand temperatures up to 1790 °C. It can be mixed with demineralised water. The mixture results in a moulding paste which must be shaped and dried. This paste can be poured onto all non-absorbent materials. The moulds should have sufficient vents to allow proper casting.  RTC-70 mouldable ceramic is available in 3.6 kg.  For larger sizes, please contact us. We offer other  moulding ceramics  with unlimited applications at high temperatures.
