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.

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. The optimum storage
temperature is between 10 °C and 30 °C. Lower and higher storage temperatures
are not preferable and should be avoided.
