Superwool® Refractory Coatings and Mastics are high-performance materials designed to protect, repair and enhance fibre insulation systems operating in demanding thermal environments. Combining low biopersistent Superwool fibre technology with specialist binders and proprietary formulations, these products provide effective solutions for crack sealing, hot-face protection, refractory repairs and insulation maintenance.
Designed for application by trowel, caulking gun, hand moulding or pumping systems, Superwool coatings and mastics deliver excellent thermal stability, strong adhesion and long-term durability while helping restore and extend the performance of high-temperature insulation linings.
Superwool products provide reliable protection, repair and sealing performance for fibre-lined and refractory systems.
