| N,N-DIMETHYLETHANOLAMINE |
| PRODUCT NAME: |
N,N-DIMETHYLETHANOLAMINE |
PRODUCT CODE: |
JD DMEA |
| CAS NO.: |
108-01-0 |
| EMPIRICAL FORMULA: |
C4H11NO |
| GENERAL 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. |
