Usage:
BDMA is the catalyst of polyester polyurethane block soft foam, polyurethane hard foam, polyurethane sheet and adhesive coating in the polyurethane industry, mainly used for hard foam, which can make polyurethane foam have good early fluidity and uniform foam pores, and foam body has good adhesion with the substrate;
BDMA is mainly used in the field of organic synthesis as a catalyst, corrosion inhibitor, acid neutralizer, and accelerator for embedding electron microscopy sections in the synthesis of dehydrogenated halogens in organic drugs;
BDMA is also used for synthesizing quaternary ammonium salts and producing cationic surface active strong fungicides, etc;
BDMA is mainly used in epoxy resin to promote curing systems such as acid anhydrides, polyamides, and fatty amines, accelerate product curing, and is widely used as a curing accelerator in epoxy resin electronic encapsulation materials, encapsulation materials, epoxy floor coatings, and ship paints;
The specific application examples of BDMA include: carbon fiber/single-molecule epoxy resin based composite laminates, electrophoretic coatings for epoxy substrates, and dry transformer sealing adhesives;
Benzyl dimethylamine, mainly used for rigid foam, can make polyurethane foam have good early fluidity and uniform foam pores, and can improve the adhesion between foam body and substrate. The recommended addition amount is 3-5 PPHP (per 100 parts of polyol)
