Spraying series

The spray series spray number is a fast and timely sealing spray sealing product. It is mainly used for the rapid sealing of various fracturing sealing walls in underground mines, sealing walls of gas leakage, roadways, coal mining face corners and roof surface cracks and air leakage. Block and seal to prevent coal oxidation, spontaneous combustion and leakage of harmful gases.
This product is a liquid modified organic polymer resin material. It is composed of component B. After spraying, it can react within a few seconds and solidify quickly into a high-expansion foam coating with good flexibility. The product has no It is poisonous, has strong adhesion, does not fall off, does not crack, has high tensile strength, and has good protection and sealing properties.
Product advantages
Fast foaming speed, high foaming multiple, adjustable reaction time
The spray coating has good sealing performance and can block air leakage and harmful gases
Flame retardant and antistatic Good performance
Good adhesion to coal and rock walls and various wall surfaces
