BDMA in the polyurethane industry is a catalyst for polyester-type polyurethane block soft foam, polyurethane rigid foam, polyurethane sheet and adhesive coatings, mainly used in rigid foam, can make polyurethane foam with good pre-fluidity and homogeneous vesicles, the foam body and the substrate between the adhesion of a better;

BDMA is mainly used in the field of organic synthesis as catalyst for synthesizing dehydrohalogen in organic drugs, corrosion inhibitor, acid neutralizer, accelerator for electron microscope section embedding;

BDMA is also used in the synthesis of quaternary ammonium salts, the production of cationic surface-active powerful bactericides and so on;

BDMA in epoxy resin, mainly used to promote the curing system of acid anhydride, polyamide, fatty amine, etc., to accelerate the curing of the product, widely used in epoxy resin electronic potting materials, encapsulation materials, epoxy floor coatings, marine paints as a curing accelerator;

Specific application examples of BDMA are: carbon fiber/monomolecular epoxy resin-based composite laminates, electrophoretic coatings for epoxy substrates, and dry transformer potting compounds;
