Product description：
High temperature kiln refractory lining is prone to cracking and falling off under harsh conditions, resulting in fire and heat loss, short service life of refractory materials, high energy consumption per unit product, long maintenance cycle and high cost. Redon high temperature thermal protection coating is a new type of high temperature resistance, wind erosion resistance and cracking resistance products specially designed for the above problems.
Redon high temperature protective coating is a slurry based on alumina fiber and refractory filler. It is applied on the surface of refractory material by manual or mechanical spraying, which can significantly improve the high temperature resistance and wind erosion resistance of refractory lining.
High temperature protective coating has been widely used in high temperature, high wind speed thermal environment, is the aluminum carbon industry fire channel wall, the ideal protective material and quick repair material. Compared with traditional repair materials such as refractory cement, this product has longer service life, more economical and more energy saving.
Product category:
Type 1300 protective coating RDGW-1300
Type 1400 protective coating RDGW-1400
Type 1500 protective coating RDGW-1500
