TRL SMA 90K is a premium-grade High Alumina Refractory Mortar manufactured by TRL Krosaki Refractories Limited, one of the leading refractory manufacturers in the world. It is specially formulated to provide exceptional bonding strength, excellent workability, superior thermal stability, and long-lasting performance for refractory brick installations operating under extremely high temperatures.
Developed using carefully selected high-purity alumina, refractory aggregates, special binders, and performance-enhancing additives, TRL SMA 90K is designed to produce strong and durable joints between refractory bricks. The mortar ensures excellent adhesion while maintaining dimensional stability during continuous exposure to intense heat, thermal cycling, and mechanical stress.
Modern industries such as steel manufacturing, cement production, power generation, foundries, petrochemical processing, and waste incineration require refractory lining systems capable of delivering reliable performance for extended operating periods. TRL SMA 90K has been developed specifically to meet these demanding industrial requirements by ensuring strong refractory brick bonding and enhanced lining durability.
Product Overview
TRL SMA 90K is supplied as a ready-to-use dry refractory mortar that requires only the addition of clean water before application. Once properly mixed, it produces a smooth and workable mortar suitable for laying high alumina refractory bricks in various high-temperature installations.
The mortar fills joints uniformly, providing excellent adhesion and minimizing gaps that could otherwise reduce furnace efficiency or allow hot gas penetration. After proper curing and controlled heat-up, the mortar develops high mechanical strength and forms durable joints capable of withstanding prolonged exposure to elevated temperatures.
Its superior bonding properties make it an ideal choice for new refractory lining installations as well as maintenance and repair work.
