Two Component Abrasion Resistant Polyurea
Polyurea materials are divided into two-component sprayed polyurea and one-component hand scraped polyurea. Both materials have high abrasion resistance, good anti-seepage effect, strong corrosion resistance and excellent physical and mechanical properties. Polyurea material has high impact and wear resistance, good anti-seepage effect, corrosion resistance and excellent physical and mechanical properties. It has been widely used in industrial and civil buildings, water conservancy and Hydropower projects, national defense construction, etc. The two-component spraying polyurea raw material system contains no solvent, has fast curing speed and simple process. It can be easily sprayed on facades and surfaces with a coating of tens of millimeters thick without flowing.
