application
2,2-bismorpholinyl diethyl ether is suitable for use in water curing systems. It is a strong foaming catalyst. It can prolong the storage period of NCO components due to the steric hindrance effect of amino groups. It is suitable for TDI, MDI, IPDI, etc. Catalytic reaction of NCO and water in the system; 2,2-bismorpholinyl diethyl ether is mainly used in one-component rigid polyurethane foam systems, and also in polyether and polyester polyurethane soft foams, semi-rigid foams, The CASE material or the like is added in an amount of 0.3 to 0.55% of the polyether/ester component.
