| description | 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.
L'invention concerne une composition élastomère de silicone qui est stable au stockage et se durcit en un corps élastomère, cette composition comprenant (i) un polymère d'organopolysiloxane contenant au moins deux groupes hydroxyle ou hydrolysables ; (ii) un agent de réticulation siloxane et/ou silane contenant au moins trois groupes par molécule qui peuvent réagir avec les groupes hydroxyle ou hydrolysables dans le polymère d'organopolysiloxane (i) ; (iii) une résine d'organosilicate solide sensiblement non réactive avec les composants (i) et (ii) et contenant des unités siloxane R23SiO1/2 et des unités de siloxane SiO4/2, le rapport molaire des unités siloxane R23SiO1/2 et des unités siloxane SiO4/2 étant de 0,5 : 1 à 1,2 : 1, R2 étant sélectionné parmi des groupes hydrocarbonés ; et facultativement (iv) un catalyseur de durcissement par condensation approprié. La résine d'organosilicate non réactive est utilisée pour créer une composition de silicone vulcanisable à température ambiante (RTV) à faible module qui, une fois durcie, peut servir de revêtement, d'adhésif ou d'agent d'étanchéité à capacité de mouvement élevée. |
