1523105 RTV silicone rubber compositions RHONE-POULENC INDUSTRIES 22 March 1977 [24 March 1976] 12077/77 Heading C3T Organopolysiloxane compositions contain the same components as in Specification 1,438,472 but in different proportions giving shorter vulcanization times, viz: per 100 parts by weight alpha - # - dihydroxy - diorganopolysiloxane (at least 600 cP/25‹ C.) there are 8À1 to 60 parts organosilicon resin consisting of R13SiO0À5 and SiO2 units in molar ratio from 0À4 : 1 to 1À2 : 1 (instead of 0À5 to 8 parts); 2 to 25 (instead of 1 to 5) parts of the defined alkoxylated organosilicon compound; and 0À5 to 18 (instead of 0À2 to 6) of one of a number of specified categories of organic titanium compound.
