BDMA in the polyurethane industry is a catalyst for polyester polyurethane block soft foam, polyurethane rigid foam, polyurethane sheet and adhesive coating , Mainly used for rigid foam, can make polyurethane foam have good initial fluidity and uniform cells, and have better adhesion between foam and substrate;

BDMA In the field of organic synthesis, it is mainly used as a catalyst, corrosion inhibitor, acid neutralization for the synthesis of dehydrohalogen in organic drugs Accelerators, electron microscope slice embedding accelerators, etc.;

BDMA is also used in the synthesis of quaternary ammonium salts, the production of cationic surface active powerful fungicides, etc.;

BDMA In epoxy resin, it is mainly used to promote the curing system of acid anhydride, polyamide, aliphatic amine, etc., and accelerate the curing of products. Used as a curing accelerator in epoxy resin electronic potting materials, encapsulating materials, epoxy floor coatings, and marine paints;

BDMA Specific application examples include: carbon fiber/monomolecular epoxy resin-based composite laminates, electrophoretic coatings for epoxy substrates , Dry-type transformer potting glue;

Features and uses:

A liquid tertiary amine catalyst. Can improve foam cure and demolding time. It is an excellent candidate to consider for use in water-NCO reaction in rigid polyurethane foams.

BDMA is typically suitable to replace DMCHA in formulations using a high level of water as blowing or co-blowing agent can reduce surface friability and improve adhesion of foam to substrates.

BDMA promotes the urethane reaction and is commonly used in high-water rigid foam applications to reduce friability. It has a characteristic but low amine odor, and is soluble in water and in most organic solvents.

BDMA is used in flexible slabstock and rigid foam applications.

It promotes the urethane reaction and is commonly used in high-water rigid foam applications to reduce friability.

BDMA is also used for flexible slabstock foam applications.

Storage Information 

Recommends that our catalysts be stored in a dry and cool area under appropriate ventilation conditions. Each container should be closed tightly to avoid contamination with moisture or other negative influences that could change the products’ performance in the end use.
