Dimorpholinodiethyl ether

Dimorpholinodiethyl ether (CAS 6425-39-4 ), commonly known by its abbreviation DMDEE, is a tertiary amine compound used as a reactive catalyst in polyurethane and polymer systems. It accelerates curing reactions, particularly in moisture-triggered and one-component formulations, without requiring post-cure removal. This makes it a primary catalyst choice in one-component polyurethane sealants. In these applications, it drives moisture-cure reactions at ambient temperature to achieve fast skin formation and through-cure. In construction and building products, it enables reliable cure performance. This includes roofing membranes, joint sealants, and gap fillers across variable humidity conditions. Polyurethane foam systems, including spray foam insulation, use it to balance gel and blow reactions. This gives formulators control over cell structure and rise time. Its reactivity profile also suits crosslinking applications in elastomers and coatings where controlled cure onset is a requirement. The product is supplied as a liquid at standard commercial purity levels, typically 98% or higher. It is available in technical grade, the standard specification for industrial catalyst applications. Packaging ranges from drums to IBC totes, with bulk options available depending on volume requirements. This ensures flexibility for various manufacturing scales and logistical needs in the chemical industry. Contact us for supply of Dimorpholinodiethyl ether Request Quote
