MOFAN DMDEE: Latent Moisture Activated Catalyst Drives Tin Free Transformation for Global Polyurethane Industry
As a high-performance tin-free latent catalyst tailored for one-component moisture-curing polyurethane systems, 2,2′-dimorpholinyldiethyl ether (DMDEE, CAS#6425-39-4) has become a core upgrading material for modern environmentally friendly polyurethane formulations. With a molecular formula of C₁₂H₂₄N₂O₃ and a molecular weight of 244.33, DMDEE features a unique moisture-triggered latent activation mechanism, which is fundamentally different from conventional instant-response amine catalysts that start cross-linking immediately after being added to PU prepolymers. It remains chemically inert under sealed, fully anhydrous storage environments. Within one-component PU packaging systems, it will not cause abnormal viscosity rise, premature gelation or batch failure during long-term warehouse storage. Catalytic activity is unlocked only when construction commences and the compound makes contact with water vapour from ambient air. This special property perfectly matches the core design logic of one-component moisture-curing polyurethane: long-term stable storage in sealed containers and controllable curing after exposure to atmosphere. Therefore, MOFAN-grade DMDEE finds broad applicability in aerosol one-component foam (OCF), PU waterproof injection grouting, moisture-curing construction sealants, HMPUR hot-melt adhesives, single-component floor coatings, polyester polyurethane foams and polyurethane elastomer products.
MOFAN DMDEE is produced through multi-stage fine purification procedures. The finished product is colourless to light-yellow transparent liquid. Its minimum assay reaches 99.00 %, and water content is strictly controlled at maximum 0.50 %. Core physical indicators keep stable among different production batches: specific gravity hits 1.06 g/cm³ at 20 °C, viscosity registers 216.6 cst at 20 °C, flash point is 156.5 °C, and the product achieves complete miscibility with water. Standard commercial packaging adopts 200 kg sealed iron drums for moisture-proof and leak-proof transportation and stocking. Custom-tailored package specifications are also available to satisfy small-batch laboratory R&D tests as well as large-scale continuous industrial production. According to safety datasheet information, MOFAN DMDEE is not classified as dangerous goods for transportation, with its main hazard being serious eye irritation. Operators shall avoid inhaling vapour and direct skin or eye contact during handling, and stock the material in tightly-closed containers inside dry, well-ventilated warehouses, kept separately from strong acid substances.
Founded in 2018 by a seasoned technical elite group from the polyurethane sector, MOFAN POLYURETHANE CO., LTD gathers core experts owning 33-years of front-line professional experience within polyurethane raw-material synthesis, production process optimization, product development and end-use application troubleshooting. The technical team possesses thorough understanding of various PU manufacturing difficulties frequently encountered by downstream factories, and is capable of analysing practical defects such as fast skin-forming, surface wrinkling, foaming voids and slow low-temperature curing, so as to propose targeted, workable adjustment schemes.
The company’s large-scale modern manufacturing base was completed in June 2022 and formally put into production in September of the same year, delivering an annual production capacity of 100,000 tons. Its product portfolio covers comprehensive series of polyurethane tertiary-amine catalysts and special amines, including mainstream models DMCHA, PMDETA, DMAEE, BDMA, DMP-30, TMR-2, TMEDA and other specialty grades, alongside diversified special polyether polyols, such as Mannich-based polyether, hydrophilic polyether and foam cell-opening polyether. Benefiting from abundant local raw-material supply chain resources, MOFAN can also develop and customize complete polyurethane composite systems in accordance with personalized formulation demands from worldwide customers.
Corporate social responsibility and sustainable development occupy an important position in MOFAN’s operational philosophy. While creating economic returns for shareholders, the enterprise actively implements social-responsibility strategies, observes sound business ethics, prioritizes safe production protocols, attaches great importance to employee welfare, environmental protection and energy-saving production processes. Supported by regional raw-material cost advantages, advanced manufacturing equipment and mature process technology, MOFAN transfers cost benefits to partners, supplying high-performance yet cost-effective raw materials to help customers improve overall product profit margins. Different from simple raw-material traders, MOFAN operates a professional technical service team. Apart from standard catalogue products, it accepts customized product development requests. Specialists can recommend suitable catalyst grades, guide correct addition dosage, assist customers to lower formulation cost, develop brand-new materials and resolve tricky practical application technical obstacles.
All production activities follow ISO9001:2015 quality-management system standards. Full-chain quality control runs through raw-material incoming inspection, real-time production monitoring, finished-product laboratory testing and pre-shipment re-verification. Every production batch undergoes strict testing on purity, moisture content, viscosity and catalytic performance to guarantee stable and consistent quality across batches. MOFAN’s catalyst and polyether product lines have been exported to numerous countries around the globe. Consistent product quality, efficient order delivery and competitive pricing have won long-term trust and repeated cooperation from overseas clients.
As tin-free formulation turns into an irreversible global trend for polyurethane high-end products, DMDEE represents one of the most feasible technical routes for one-component moisture-curing system upgrading. MOFAN does not limit its business scope merely to supplying high-purity DMDEE chemicals. The company provides full-package downstream technical solutions, including formulation debugging guidance, production-process consultation and on-site defect elimination support. Looking ahead, MOFAN POLYURETHANE CO., LTD will keep investing in latent eco-friendly catalyst research and development, continuously refine DMDEE product performance and matching application solutions. By deep-dive technical accumulation and open-minded global cooperation, MOFAN aims to jointly promote the green, high-end development of the international polyurethane industry and pursue mutual win-win outcomes with partners from all over the world.
