Drizoro - Maxmorter Heat 750 refractory mortar

Fireproof mortar made of special cement and aggregates that can withstand temperatures up to 750 C. It is intended for laying wall coatings and bricks that function in extreme conditions of high temperatures or come into direct contact with fire.

Features

• despite contact with high temperatures, it maintains good mechanical resistance
• excellent adhesion to the substrate
• good chemical resistance to dilute acids, sulphates and sewage
• not susceptible to moisture and water, it can be used outdoors
• good workability and lump-free thixotropy
• non-toxic and non-flammable, environmentally friendly
• odorless, can be used in poorly ventilated rooms
• one-component, it is ready for use after mixing with water

Application

• laying bricks and elements in furnaces, industrial equipment, chimneys, etc., exposed to extreme thermal cycles
• refractory coating of substrates operating at very high temperatures or in contact with open flames
• repairing, refilling and leveling bricks and damaged joints between them
• in metallurgical plants, steel and heavy industry, glass and ceramics, incinerators, equipment in refineries and petrochemical plants: conventional and smelting furnaces, dryers, heating systems, chemical reactors, etc.
