Mainly used for spraying polyurea elastomers, RIM products, epoxy resin curing agents, etc. Spray polyurea elastomers made from terminal amino polyethers and isocyanates have high strength, elongation, friction resistance, corrosion resistance, and aging resistance. They are widely used as waterproof, anti-corrosion, and wear-resistant coatings on concrete and steel structures, as well as protective and decorative coatings on other components. Amino terminated polyether is used as a curing agent for epoxy resin, which can improve the toughness of products and is widely used in the manufacturing of epoxy resin handicrafts.
