摘要: Novel hindered alkoxy siloxane compounds and compositions containing hindered alkoxy siloxane compounds are provided. The compositions include a polymer/crosslinking system which is composed of a self crosslinking resin comprised of a silicone fluid modified with pendant or terminal silanes containing hindered alkoxy groups, or a silanol fluid and a crosslinking compound, of a mixture thereof. These components are first emulsified and then formulated into a latex sealant by blending with a separate emulsion of an appropriate catalyst. Crosslinking occurs upon drying of the emulsion.
