    Abstract: The present invention comprises a curable composition comprising: (i) a blocked reactive component comprising a blocked isocyanate or a blocked isothiocyanate; (ii) a functional component containing reactive hydrogen; (iii) a triorganotin catalyst for promoting the reaction of the blocked reactive component with the functional component. The composition may also be admixed with water. A co-catalyst may also be employed based on Cu, Zn, Ni, Fe, Co, V, Sb and Bi and especially oxides, salts or chelates of said metal where said metals are divalent. The invention also relates to a method for curing a blocked isocyanate or blocked isothiocyanate at a temperature below about 150 DEG C which comprises combining a triorganotin catalyst with the blocked reactive component and functional component and heating at a temperature less than about 150 DEG C to obtain a cured urethane or thiourethane.

    Abstract translation: 本发明包括可固化组合物，其包含：（i）包含封端异氰酸酯或封端异硫氰酸酯的封闭反应性组分; （ii）含有反应性氢的功能组分; （iii）用于促进阻断的反应性组分与官能组分的反应的三有机锡催化剂。 组合物也可以与水混合。 还可以使用基于Cu，Zn，Ni，Fe，Co，V，Sb和Bi的助催化剂，特别是所述金属的二价氧化物，盐或螯合物。 本发明还涉及一种在低于约150℃的温度下固化封端的异氰酸酯或封闭的异硫氰酸酯的方法，该方法包括将三有机锡催化剂与封闭的反应性组分和官能组分组合并在小于约150℃的温度下加热得到 固化的氨基甲酸酯或硫代氨基甲酸酯。
