In the polyurethane industry, BDMA is a catalyst for polyester polyurethane block soft foam, polyurethane rigid foam, polyurethane sheet and adhesive coatings. It is mainly used for hard foam, which can provide polyurethane foam with good early fluidity and uniform cells. Good adhesion between foam and substrate;
In the field of organic synthesis, BDMA is mainly used as a catalyst for the synthesis of dehydrohalogen in organic drugs, corrosion inhibitors, acid neutralizers, accelerators for embedding electron microscope slices, etc.;
BDMA is also used to synthesize quaternary ammonium salts and produce cationic surface active powerful fungicides, etc.;
In terms of epoxy resin, BDMA is mainly used to promote curing systems such as anhydrides, polyamides, and fatty amines to accelerate product curing. It is widely used in epoxy resin potting materials, encapsulating materials, epoxy floor coatings, and marine paint Used as curing accelerator;
Specific application examples of BDMA are: carbon fiber/monomolecular epoxy resin-based composite laminates, electrophoretic coatings of epoxy substrates, and dry-type transformer encapsulants;

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.
