Product Introduction
DMAEE (2-Dimethylaminoethoxyethanol) CAS 1704-62-7
– Low Odor Tertiary Amine Catalyst for Polyurethane Foam Manufacturing
1. Introduction
DMAEE, full chemical name 2-Dimethylaminoethoxyethanol, is a water-compatible tertiary amine polyurethane catalyst with CAS number 1704-62-7. It appears as a colorless transparent low-viscosity liquid with mild odor, balancing strong gel catalytic activity and moderate foaming promotion performance. Different from traditional high-odor amine catalysts, DMAEE features low volatility, good water miscibility and long-lasting catalytic efficiency, becoming a universal core catalyst for flexible PU foam, rigid insulation foam, and water-based polyurethane systems.
We operate a specialized polyurethane catalyst manufacturing factory covering a total area of 100 acres, equipped with fully automated continuous synthesis & rectification production lines, independent high-precision QC laboratory and standardized full-cycle wastewater & solid waste treatment stations. Our team consists of 150 skilled frontline production workers and 30 full-time professional technical engineers, taking charge of raw material feeding, amine synthesis, vacuum distillation purification, batch full-index testing and environmental waste resource recovery respectively. We maintain long-term joint research cooperation with multiple universities and chemical environmental research institutes, focusing on green craft optimization for a complete series of polyurethane catalysts including DMAEE. Our joint R&D projects focus on three core research directions: low-by-product green synthesis technology for DMAEE and other amine catalysts, product purification upgrading to reduce free amine residual and lower VOC emission, and closed-loop harmless recycling solutions for production wastewater and solid waste residues. All batches of our DMAEE deliver stable gel/foam balance activity, ultra-low free amine impurities and consistent viscosity, perfectly matching formulation requirements of PU foam factories, refrigerator insulation material manufacturers, furniture sponge plants and water-based coating compound enterprises. We provide complete English export compliance documents, stable mass spot inventory and free PU formula technical support for global chemical distributors and polyurethane processing manufacturers.

7. FAQ
Q1: What is DMAEE used for in polyurethane production?
A: DMAEE (2-Dimethylaminoethoxyethanol) is a low-odor tertiary amine polyurethane catalyst. It provides balanced foaming and gel catalytic effects, mainly used to manufacture flexible furniture sponge, refrigerator rigid insulation foam, water-based polyurethane coatings, automotive interior foam and microcellular PU shoe sole materials, accelerating foaming reaction and optimizing finished foam cell structure and dimensional stability.
Q2: What production advantages does your DMAEE manufacturing factory have compared with other suppliers?
A: Our factory covers a total area of 100 acres, with 150 skilled production workers and 30 full-time professional technical R&D engineers. We cooperate with multiple universities and environmental research institutes to research green low-emission synthesis technology for DMAEE and a full series of polyurethane catalysts. Our R&D team continuously upgrades product purity to lower free amine odor and develops closed-loop recycling treatment technology for production wastewater and solid waste residues, providing low-VOC stable DMAEE and free PU foam formulation technical support for global polyurethane manufacturers.
Q3: Is your DMAEE EU REACH registered for bulk export to European polyurethane foam factories?
A: Yes, our DMAEE substance holds complete ECHA EU REACH registration dossier with authorized EU Only Representative (OR). We can provide full batch SVHC test reports, low-VOC environmental certification and official compliance declaration to support smooth customs inspection in all EU member countries without detention risks.
Q4: What negative impacts will excessive free dimethylamine impurity in DMAEE bring to finished polyurethane foam?
A: Excess free dimethylamine will cause strong irritating odor of finished foam, increase volatile organic content and fail EU low-emission furniture material standards. It will also lead to uneven foam cells, sticky surface and easy shrinkage of rigid insulation foam. Our DMAEE strictly limits free amine residual ≤0.08% to completely avoid such production defects.
Q5: Can I get free lab test samples of DMAEE before bulk order? Do you offer volume wholesale discount?
A: We supply small lab trial samples of DMAEE for PU foam formula testing and catalytic performance verification. Competitive preferential unit prices are offered for long-term cooperative large foam factories and global chemical distributors. Our 30-person professional technical team can provide free customized catalyst dosage optimization guidance for flexible slabstock, rigid insulation and water-based PU different production lines.
Q6: What is the shelf life of sealed DMAEE liquid? What storage risks need to be noticed?
A: Under tightly sealed cool and dry warehouse storage conditions, the shelf life of DMAEE reaches 18 months. DMAEE is alkaline amine liquid, must be stored separately from MDI, TDI and other isocyanate raw materials to prevent cross-contact curing reaction. High temperature storage will accelerate volatile loss and reduce catalytic balance performance.
