    摘要： The present invention provides curable compositions comprising non-Sn organo-metal catalysts that accelerate the condensation curing of moisture curable silicones/non-silicones. In particular, the present invention provides Mn(III) complexes that are particularly suitable as replacements for organotin for sealant and RTV formulations. The Mn(III) complexes are comparable or superior to organotin such as DBTDL, superior to Mn(II) compounds, and exhibit certain behavior in the presence of components that allow for tuning or adjusting the cure characteristics of the present compositions and provide good adhesion and storage stability.

    摘要： Disclosed herein is a method for producing a 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine. The method comprises forming a reaction mixture comprising at least one substituted or unsubstituted phenolphthalein, at least one substituted or unsubstituted primary hydrocarbyl amine, and an acid catalyst; and heating the reaction mixture to a temperature of less than 180° C. to remove a distillate comprising water and form a crude 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine product; where the 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine has a formula: where R1 is selected from the group consisting of a hydrogen and a hydrocarbyl group, and R2 is selected from the group consisting of a hydrogen, a hydrocarbyl group, and a halogen.

    摘要： The present invention provides curable compositions that are substantially free of metal catalysts including both tin and non-tin metal catalysts. The curable compositions employ a catalyst system comprising the combination of a carboxylic acid, an amino-containing adhesion promoter or a mixture of amine-containing adhesion promoters and an amino-containing siloxane. The combination of these materials accelerates the condensation curing of moisture curable silicones/non-silicones even in the absence of a metal-based catalyst.
