ROOM TEMPERATURE-CURABLE POLYORGANOSILOXANE COMPOSITION WHOSE CURED PRODUCTS RESIST SOILING

摘要

A room temperature-curable polyorganosiloxane composition is provided which comprises a polyorganosiloxane which possesses at least one silicon-bonded oxyalkylene radical of the general formula -R1O(R2O)nR3 wherein R1 and R2 are a divalent alkylene radical, R3 is a radical selected from alkyl, acyl or hydrogen and n is 0 or an integer with a value 1, with the polyorganosiloxane having at least 2 silanol groups per molecule and a curing agent. The composition is useful as a sealent, caulking material, potting material, etc. with the additional property that although it adheres to another substrate the composition resists soiling.
