THERMOSEAL® Refractory Moldables are high-temperature resistant mixes designed for use as molten non-ferrous trough linings, furnace lining repair and patching, and fireplace applications.

Available in both high density and low density formulas, THERMOSEAL® Refractory Moldables can be formed into shapes, pushed into cracks and holes, or spread into thin sections as surface coatings.

The refractory moldables are available in a range of consistencies suited to many applications, including dry moldable, pumpable moldable, and non-wetting moldable.
