Applications of D230

It is mainly used for spraying polyurea elastomer, rim products, epoxy resin curing agent, etc. The sprayed polyurea elastomer prepared from amino terminated polyether and isocyanate has high strength, high elongation, friction resistance, corrosion resistance and aging resistance. It is widely used in waterproof, anti-corrosion and wear-resistant coatings on the surfaces of concrete and steel structures, as well as protective and decorative coatings on other components. Amino terminated polyether used in epoxy resin curing agent can improve the toughness of products, and is widely used in the manufacture of epoxy resin crafts.
Preparation:synthesis of Poly(propylene glycol) bis(2-aminopropyl ether): Firstly, the polyether is attached to the acetoacetate group at both ends by dienone or through the ester exchange reaction of ethyl acetoacetate with polyether polyol, and then the polyether capped by the acetoacetate group is aminated with a mono-primary amine, alkyl alcohol amine or dibasic primary amine to obtain an imine compound with a low viscosity with an aminobutyrate end group.
