Description
2-Dimethylaminoethanol (CAS 108-01-0) is a short-chain aliphatic amine supplied under trade names including DMAE and Deanol. It carries EC number 203-542-8 and molecular formula C4H11NO. No E-code designation applies to this substance.
In waterborne coatings, DMAE neutralises acidic resin systems to control dispersion stability and adjust application pH without introducing metal ions. In water treatment and metalworking fluids, it functions as a corrosion inhibitor by forming a protective amine layer on metal surfaces. It also serves as a catalyst in polyurethane and epoxy formulations, accelerating cure at controlled rates.
The material is available in technical and high-purity grades and is subject to REACH registration requirements for EU supply. Procurement quantities typically range from drums to IBC and bulk tanker. Buyers should confirm grade suitability against relevant pharmacopoeial or industry specifications prior to use.
