Abstract: Vinyl ester resins processed until low epoxy values are reached, are storage stable for two weeks at 54 DEG C (130 DEG F). Adding a copper salt inhibitor also provides two weeks storage stability at 54 DEG C (130 DEG F). A synergistic effect is observed if both low epoxy values are reached and copper naphthenate inhibitor is used, extending shelf life stability to two months at 54 DEG C (130 DEG F).

Abstract: 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.

Abstract translation: 本发明涉及一种锡或铋催化剂/巯基络合物，其在初始形成后长时间储存​​后显示出基本相同的稳定性和活性。 这通过将催化剂络合物的载体限制为在催化剂体系延长储存时不与巯基化合物反应的载体来实现。 这些载体包括芳烃和萜烯。 酮类车辆不包括在内。 优选的载体包括甲苯，二甲苯，松节油和d-柠檬烯。 要求形成稳定的催化剂络合物的方法。 通过消除酮类载体，聚合物巯基/多异氰酸酯树脂配方被称为更稳定。 通过与丙烯酸树脂共混可以延缓树脂配方的固化速度。 还可以使用稳定的锡催化剂络合物。
