As a catalyst foaming reactions, is also used to balance the overall reaction of foam and gel

Application Overview

5-ethyl-3-methyl-2 sub-amine reaction is a highly active catalyst for polyurethane, foam it to catalytic reactions, is also used to balance the overall reaction of foam and gel. Because of its strong foaming effect, to improve liquidity bubble, so to improve production processes and increase system capacity, it is often shared with DMCHA so. Alone as a foam catalyst, the dosage range of 1.0-2.0 without polyols were 100.

Except for the rigid foam formulations, 5-ethyl-3-methyl-2 sub-amine can also be used to block polyether polyurethane foam and molded foam production. For example, 70% ethylene triamine Wujia two soft foam products mainly used in the formula, the major catalyst, foaming speed, products with high toughness and high load resistance. In the soft polyether foam in every 100 will be the catalyst 0.1-0.5 were good results after payment. Foam can be used as auxiliary catalyst.
