N,N-Dimethylethanolamine is a bifunctional tertiary amine and primary alcohol extensively utilized as a catalyst in polyurethane foam production and as a pH neutralizing agent in waterborne industrial coating formulations. This chemical intermediate, commonly identified in the industry as 2-(Dimethylamino)ethanol or DMEA, also serves as a critical precursor in the synthesis of flocculants and ion-exchange resins due to its reactive amine functionality. We offer this essential raw material with competitive factory pricing to support large-scale manufacturing operations. Our supply chain capabilities ensure bulk supply availability and customized specifications to meet precise technical requirements, accompanied by full MSDS, TDS, COA documentation for quality assurance and compliance.

FAQ - Technical & Supply Chain
-
Q:
Does N,N-Dimethylethanolamine correspond to the standard MEA or the specific methylated tertiary amine?
A: N,N-Dimethylethanolamine is verified under CAS 108-01-0 as the tertiary amine 2-(Dimethylamino)ethanol, distinguishing it from Monoethanolamine (MEA) or Diethylethanolamine (DEEA) to ensure the correct base strength and volatility profile required for resin neutralization. -
Q:
Why is N,N-Dimethylethanolamine preferred over ammonia as a neutralizer in water-borne coatings?
A: N,N-Dimethylethanolamine is typically applied as a neutralizing agent for acid-functional resins because it provides superior pH stability, lower odor, and enhances the water solubility of alkyds and acrylics without causing the yellowing often associated with other amines.
