(57) [Summary] [Purpose] A one-pack type room temperature curable silicone elastomer that adheres to polyacrylates without a primer and is useful as a sealant. [Structure] The one-part room temperature curable silicone elastomer of the present invention comprises (a) a dimethyl silicone polymer terminated with a polyalkoxysilane, (b) an alkoxysilane cross-linking agent, and (c) R 2 Sn (β-diketonate). A low concentration tin-based condensation curing catalyst selected from the group of 2 complexes, (D) Epoxysilane-based adhesion promoter, (e) Acrylic-functional or methacrylic-functional alkoxysilane-based adhesion promoter, and (f) Polyalkoxysilylalkylisocyanurate. |
