Abstract
A silicone elastomer composition which is generally storage stable, and cures to an elastomeric body, comprising; (i) an organopolysiloxane polymer having at least two hydroxyl or hydrolysable groups; (ii) a siloxane and/or silane cross-linker having at least three groups per molecule which are reactable with the hydroxyl or hydrolysable groups in the organopolysiloxane polymer (i); (iii) a solid organosilicate resin which is substantially unreactive with components (i) and (ii) and comprising RSiOand SiOsiloxane units, wherein the molar ratio of the RSiOsiloxane units to SiOsiloxane units is from 0.5:1 to 1.2:1, and Ris selected from hydrocarbon groups; and optionally (iv) a suitable condensation cure catalyst. The solid organosilicate resin (iii) is generally utilised to create a low modulus room temperature vulcanisable (RTV) silicone composition which when cured may be used as a coating, an adhesive or a sealant having high movement capability.
