Product description: PRODUCT NAME:N,N-DIMETHYLETHANOLAMINE PRODUCT CODE: DMEA CAS No. :108-01-0 EMPIRICAL FORMULA : C4H11NO GENERAL DESCRIPTION: 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 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, DMEA catalyst should be replaced with a stronger amine catalyst such as TEDA catalysts. ADVANTAGES: Low cost Delayed front end reactivity Non-fugitive catalysis APPLICATIONS: Polyether flexible slabstock foams MDI high resiliency flexible moulded foams Rigid bunstock Energy absorbing non-recoverable rigid systems TYPICAL PROPERTIES: Flash Point, °C (PMCC) 44 Viscosity at 25°C 6 Specific Gravity at 25°C [g/cm_] 0,89 Water Solubility Soluble Appearance Clear, Colourless to Yellow Liquid Calculated OH number [mgKOH/g] 638
