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.

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.
