ROOM TEMPERATURE VULCANISABLE SILICONE COMPOSITIONS
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 R.sub.3.sup.2SiO.sub.1/2 and SiO.sub.4/2 siloxane units, wherein the molar ratio of the R.sub.3.sup.2SiO.sub.1/2 siloxane units to SiO.sub.4/2 siloxane units is from 0.5:1 to 1.2:1, and R.sup.2 is 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.
