  公开号：EP0076630A2

  公开（公告）日：1983-04-13

  A composition containing a chelated titanium compound and an additive selected from the group consisting of (1) esters of thioalkanoic acids, (2) di-tertiary-butyl phenol containing compounds, (3) organic phosphites, and (4) mixtures of (2) and (3), retards the color change of the composition on storage. When this composition is used as the catalyst for one package, room temperature curing silicone elastomeric compositions of the type comprising a hydroxyl endblocked polydiorganosiloxane and a silane having an average of from 2.01 to 4 Inclusive alkoxy radicals, the silicone elastomeric composition can be stored without substantial color formation. The improvement in reduced color change is useful in silicone elastomeric compositions which are clear or light colored.

  一种含有螯合钛化合物和选自以下组别的添加剂的组合物可以延缓组合物在储存过程中的颜色变化：(1) 硫代烷酸酯；(2) 含二叔丁基苯酚的化合物；(3) 有机亚磷酸酯；(4) (2)和(3)的混合物。 当这种组合物用作一包室温固化的有机硅弹性体组合物的催化剂时，该有机硅弹性体组合物在储存过程中不会形成大量颜色。 在减少颜色变化方面的改进适用于透明或浅色的有机硅弹性体组合物。
