The present invention aims to provide a curable composition that exhibits excellent curability without containing an organotin curing catalyst, which is known to be toxic, gives a cured product that does not have surface discoloration even after being exposed to the atmosphere and ultraviolet light for a long time, and has no adverse influence on the environment; and a cured product thereof. The non-organotin curable composition comprises: (A) an organic polymer having a reactive silyl group; (B) an amidine compound; and (C) a chelating agent having a carbonyl group and/or a salt of the chelating agent.
本发明旨在提供一种固化组合物,该组合物不含已知有毒的有机锡固化催化剂,具有极佳的固化性,即使长期暴露于大气和紫外线中也不会产生表面褪色现象,并且不会对环境产生不利影响;及其固化产品。非有机锡固化组合物包括:(A) 具有活性硅基的有机聚合物;(B) 氨基胍化合物;和 (C) 具有羰基的螯合剂和/或螯合剂的盐。
