Refractory Coating Compound
Refracoat a special refractory coating material specially meant for protection of linings-Fire Bricks, Monolithic, Castables, Ceramic Blankets and Shells in Furnaces, Boilers and various high temperature vessels.
Main Application:
Reduces the effect of Thermal shock and to eliminate surface cracking phenomena, protects Refractories against aggressive effects of fuel oil, Gases and solid fuels.
Provides Gas tight surface and reduces energy losses.
Reduces slag adhesion.
Increase in working life of Furnace.
Reduces cost of maintenance shutdown.
Reduces fuel consumption.
