THERMOSEAL® Thermal Cements


THERMOSEAL® Thermal Cements are high-temperature resistant cements formulated to withstand thermal expansion and contraction under fluctuating heat conditions.

Our thermal cements are excellent for use when placing gaskets and seals in fireplaces and furnaces, as well as wood and coal stoves, as they adhere metal to metal and can hold a gasket in place without any burn-off. They are suitable for applications in temperatures up to 1000oF • 538oC.
