Sauereisen Electrotemp Ceramic is an excellent ceramic in applications where high electrical insulation is required and high thermal conductance is desired, as in heater elements. Coating a heater element with Sauereisen Ceramic allows you to electrically insulate the heater coils from shorting out while allowing excellent heat conductance. Other applications include mass spec probes, filaments, repair of ceramic pieces and some ceramic to metal joining.

Sauereisen No. 8 is supplied in powder form and need only be mixed with water to apply. Sauereisen hardens at room temperature or by baking. The initial set begins in approximately one to two hours and the cement continues to increase in hardness until thoroughly dried.
