摘要： The invention is directed to a tin or bismuth catalyst/mercapto complex which exhibits substantially the same stability and activity after extended periods of storage as upon initial formation. This is achieved by restricting the vehicle for the catalyst complex to one that will not react with the mercapto compound upon extended storage of the catalyst system. These vehicles include aromatic hydrocarbons and terpenes. Ketone vehicles are excluded. Preferred vehicles include toluene, xylene, turpentine and d-limonene. Methods for forming the stabilized catalyst complex are claimed. Polymercapto/polyisocyanate resin formulations are claimed as more stable by the elimination of ketone vehicles. The cure rate of the resin formulations can be retarded by blending with acrylic resins. Stabilized tin catalyst complexes may also be used.

摘要翻译： 本发明涉及锡或铋催化剂/巯基络合物，其在初始形成后长时间储存​​后表现出基本上相同的稳定性和活性。 这是通过将用于催化剂络合物的载体限制为在长时间储存​​催化剂体系时不与巯基化合物反应的载体来实现的。 这些载体包括芳烃和萜烯。 不包括酮类车辆。 优选的载体包括甲苯，二甲苯，松节油和d-柠檬烯。 要求保护用于形成稳定催化剂络合物的方法。 要求聚巯基/多异氰酸酯树脂配方通过消除酮媒介物而更稳定。 通过与丙烯酸树脂混合可以延缓树脂制剂的固化速率。 稳定的锡催化剂配合物也可以使用。
