Description and features

AminCat A-1 ( bis-2-dimethylaminoethyl-ether ) is one of the most active amine blowing catalysts available. It consists of 70% bis (2-Dimethylaminoethyl) ether diluted with 30% dipropylene glycol for ease and accuracy of metering. Although AminCat A-1 catalyzes both the blowing and gelling reactions, its unique emphasis on the isocyanate reaction has established it as the industry standard for all types of polyurethane systems where efficient catalysis of the blowing reaction is required.


Europe and United States: Provided AminCat A-1 is on stock in our local warehouses our lead time is about one week if delivered in 170 KG steel drums.

Canada, South America, South Africa and other markets can also be served, please contact our sales department for more details.

AminCat A-1 is the established blowing catalyst for all types of flexible foam. Its strong catalytic effect on the blowing reaction can be balanced by the addition of a strong gelling catalyst. When used in flexible slabstock formulations, AminCat A-1 catalyst improves the processing of all grades of foam ranging from low to high density, and from filled to high resiliency grades. The unique performance characteristics of AminCat A-1 catalyst make it an effective choice for high resiliency molded foam. In this application, a catalyst system containing both AminCat A-1 and a strong gelling catalyst will effectively meet most standard processing requirements.
