ZU ELASTOMEREN VERNETZENDE MASSEN

摘要

This invention relates to compositions which can be stored under anhydrous conditions, but when exposed to atmospheric moisture cure at room temperature to form elastomers. These compositions contain a diorganopolysiloxane having terminal condensable groups, a silicon compound having at least one nitrogen atom and at least three hydrolyzable groups per molecule, a reinforcing filler and a phosphoric acid ester. These compositions have improved stability and improved flow properties. Elastomers prepared from these compositions when compared with known compositions, have lower modulus values at 100 percent elongation.
