Detailed Product Description

JD DMEA catalyst (dimethylethanolamine) contains both a tertiary amine group and a hydroxyl group, and therefore, undergoes reactions typical of both amines and alcohols. It strongly catalyzes the water-isocyanate reaction in the production of polyurethane foam. Its hydroxyl group can react with the isocyanate, thereby chemically bonding the JD DMEA catalyst molecule to the polyurethane polymer. As a result, residual amine odour in the finished foam product is minimised. However, poor surface cure and green strength may result. When this is a concern, JD DMEA catalyst should be replaced with a stronger amine catalyst such as JD TEDA catalysts.
