CURABLE SILICONE SEALANT/ADHESIVE COMPOSITIONS

摘要

A curable silicone sealant composition, comprising first and second silicone-containing materials reactive or reacted with one another, which is useful for sealing porosity in porous materials. The composition may include platinum-catalyzed reactive silicone-containing materials in which the first material has at least 2 SiH functionalities and the second material has at least 2 ethylenically unsaturated functionalities. Alternatively, the composition may include a polymerizable organic (meth)acrylate monomer, a polymerization initiator, and a reaction product of a hydrolyzable functionality-containing silane and a (meth)acrylic functionality-containing silane.
