Abstract
The present invention provides a one-component silicone sealant composition curable when exposed to moisture at room temperature. The resulting silicone sealant has excellent stain-resistance, good overall mechanical performances and good adhesion on both dry and wet substrates. The composition contains modified hydroxyl-terminated polyorganosiloxanes polymer network in different viscosities being cross-linked with branched silicone oil in the presence of an environmental-friendly and tin-free catalyst and cross-linkers while some inert and/or functional nanofillers are added into the composition to provide mechanical and/or functional properties to the resulting silicone sealant. A method for preparing the present composition is also provided.
