One. The main use of BDMA
BDMA is a catalyst for polyester polyurethane block soft foam, polyurethane rigid foam, polyurethane sheet and adhesive coating in polyurethane industry. It is mainly used for hard foam, which can make polyurethane foam have good pre-flowability and uniform cells. Good adhesion between the foam and the substrate;
In the field of organic synthesis, BDMA is mainly used as a catalyst for synthesizing dehydrohalogen in organic drugs, a corrosion inhibitor, an acidic neutralizer, an accelerator for electron microscopy slicing, and the like;
BDMA is also used to synthesize quaternary ammonium salts to produce cationic surface active strong fungicides;
BDMA is mainly used to promote curing systems such as anhydrides, polyamides, and fatty amines, and accelerates product curing. It is widely used in epoxy resin electronic potting materials, encapsulating materials, epoxy floor coatings, and marine paints. Used as a curing accelerator;

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.
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.
