DMEA

DMEA is a clear liquid with a smell of ammonia. It has a tertiary amino group and another hydroxyl group. DMEA catalyst has a strong catalytic effect on the chemical reaction of water and isocyanate to produce polyoxy ester foam. The hydroxyl group in the catalyst can react with the isocyanate, thus the DMEA catalyst molecules can be chemically attached to the polyurethane polymer. As a result, there is very little residual ammonia odor in the foam products made by this method.

In polyurethane foams, DMEA is an auxiliary catalyst, as well as a reactive catalyst, which can be used in polyurethane soft foam and polyurethane hard foam formulations.
