What is Dimethylethanolamine?
Dimethylethanolamine (CAS 108-01-0), also known as DMAE, is a bifunctional amine-alcohol used as a pH regulator, catalyst, and corrosion inhibitor.
Where is Dimethylethanolamine used?
- Coatings and resins: neutralizes acidic binders, improving dispersion stability and film formation
- Water treatment: conditions boiler and cooling water systems, inhibiting corrosion by maintaining alkaline pH in steam condensate lines
- Polyurethane foam: catalyst controlling gel and blow reaction timing
- Metalworking fluids and lubricants: buffers pH to extend fluid service life and protect ferrous metal surfaces
- It serves as a building block and process chemical in polymer manufacturing.
Commercial specifications
- Drums, IBC totes, and tank truck quantities
