Application

D-230 has the drain and oleophobic group on the structure backbone, it is a good emulsifier agent in oil field, as a new style curing agents of epoxy, the application is tough, clear, flexible, impact-resistant coatings, castings and adhesive. In any case, D-230 amine is used in conjunction with other curing agents, contributing flexibility to the finished product,. As for non-epoxy applications Chenhua D-400 amines finds use in effective chain extender of polyurea RIM(reaction injection molding), thermoplastic polyurethane adhesives, salts, and the fluids cutting and fire retardants.
