S

auereisen Electrotemp Ceramic is an excellent ceramic in

applications where high electrical insulation is required

and high thermal conductance is desired, as in heater el-

ements.

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.

Application / Curing

Sauereisen No. 8 is supplied in powder form and need only be

mixed with water to apply.

Sauereisen hardens at room tempera-

ture or by baking.

The initial set begins in approximately one to

two hours and the cement continues to increase in hardness until

thoroughly dried.
