ROOM TEMPERATURE VULCANISABLE SILICONE COMPOSITIONS
A silicone elastomer composition which is 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 organopolysiloxane polymer (i); (iii) a solid organosilicate resin which is substantially unreactive with components (i) and (ii) comprising R23SiO1/2 siloxane units and SiO4/2 siloxane units, wherein the molar ratio of the R23SiO1/2 siloxane units to SiO4/2 siloxane units is from 0.5 : 1 to 1.2 : 1, R2 is selected from hydrocarbon groups; and optionally (iv) a suitable condensation cure catalyst. The unreactive organosilicate resin is utilised to create a low modulus room temperature vulcanisable (RTV) silicone composition which when cured may be used as a coating, adhesive or a sealant having high movement capability.
