Di-[2-(N,N-Dimethylaminoethyl)]ether

ChemaicalName: Di-[2-(N,N-Dimethylaminoethyl)]ether

Properties: This product is one of tertiary amine catalyst with the topmost activity in PU reaction at pressent. It can control the balance of foaming and geling speed well in multi-compound system of water, polyols and isocyanates. It has preferable compatibility with organic tin catalyst, additionally, only needs small dosage and smells weak, so is widely used in the production of various PU foams.

Application:

LCA-3 series with high activity, small dosage to need, used as extremely active standard amine catalyst in the whole PUR foam industry. It has wonderful catalyzing effect in the reaction of water with isocyanates, and makes foaming and gelling balanced in the reaction of polyols and isocyanates. Adjusting the dosage of LCA-3 series can control the rising time of foaming and gelling time, therefore it is synergetic effect well with tin catalyst. Lca-3 series can make the density gradent of whole lumpy foam and permanent deformation of molding foam after compressing to the least, and improve foamy uniformity, there for improving foam quality. LCA-3 series can also incease poreratio of flexible foam of flexible foam of PUR to prevent foam from contracting. LCA-3 series is a kind of liquid catalyst with weak smell, easy to dissolve in water, as a result, easy to measure during the production. It is not very harmful to the environment and widely used in various formulations for producing PUR foam, expecially fit for producing foam with high resiliency, semi-flexibility and low density.
