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.

Features and uses:

PC-37 is colorless or light yellow liquid at room temperature, soluble in water;

PC-37 is a low odor reactive catalyst for rigid packaging foam. Its structure contains active hydrogen, which can react with -NCO and combine into the system, so the smell of finished products is greatly reduced. NT CAT PC-37 can also be used for molding soft foam and polyether polyurethane soft block foam.

Storage Information:

Store in a cool and ventilated warehouse. Keep away from fire and heat. Protect from direct sunlight. Keep container sealed. It should be stored separately from oxidant and edible chemicals, and mixed storage is forbidden. Firefighting equipment of corresponding variety and quantity shall be provided.
