Refractory mortar based on special cement and aggregates, resistant to temperatures up to 1600 C. It is recommended as a mortar for laying bricks and making coatings on walls exposed to extreme conditions related to direct contact with fire or high temperature.

Features

• excellent adhesion to the substrate
• good chemical resistance to diluted acids, sulphates and sewage - better than concrete
• product non-toxic and non-flammable, environmentally friendly
• one-component material, it needs only mixing water for application
• odorless, suitable for applications in poorly ventilated areas
• despite contact with high temperatures, it shows good mechanical strength
• it does not react to water or moisture, so it can be used outdoors

Application

• as a mortar in furnaces, industrial equipment, chimneys, etc. exposed to extreme thermal conditions
• making refractory coatings on floors exposed to very high temperatures or direct contact with fire
• repair of refractory bricks and damaged mortar in the joints between them
• in metallurgical plants, iron and steel mills, heavy industry, glassworks, ceramic plants, incinerators, refinery and petrochemical equipment, furnaces, iron ore smelters, drying places, heating systems, chemical reactors, etc.
