application
DMDEE is suitable for water curing system. As a strong foaming catalyst, DMDEE can extend the storage life of NCO components due to the resistance effect of amino group, and is suitable for NCO and water catalytic reaction in TDI, MDI, IPDI and other systems. DMDEE is mainly used in single-component rigid polyurethane foam system, and can also be used in polyether type and polyester type polyurethane soft foam, semi-hard foam, CASE materials, etc., with the added amount accounting for 0.3-0.55% of the polyether/ester component.
