BASF Dimethylethanolamine DMEA

Product introduction
The chemical name for DMEA is N,N-dimethylethanolamine. It has good properties and is widely used in flocculants, coatings and polyurethane elastomers. DMEA can improve the stability of the solution when used in water-based coatings, and can enhance the scratch resistance and friction resistance of the coating. DMEA is used in CED as a chain extender for polyurethane and a catalyst for CED.
