Abstract: A hydrosilylation curable textile coating composition comprises: (a) a linear organopolysiloxane polymer having at least two alkenyl and/or alkynyl groups per molecule; (b) a reinforcing filler comprising at least one of fumed silica, precipitated silica, or calcium carbonate; (c) a cross-linker containing at least two silicon-bonded hydrogen groups per molecule; (d) a hydrosilylation cure catalyst; (e) an organosilicon resin containing M and Q units; and (f) an adhesion promoter comprising a mixture and/or reaction product of (i) one or more alkoxysilanes having an epoxy group in the molecule; (ii) a linear organopolysiloxane oligomer containing at least one alkenyl group and at least one hydroxy or alkoxy group per molecule; and (iii) an organometallic condensation reaction catalyst comprising organoaluminum or organozirconium compounds. A textile, e.g. air bag or air bag fabric, can be coated with the hydrosilylation curable textile coating composition, and resulting air bags and fabrics generally have improved properties.

Abstract: This disclosure relates to curable silicone rubber compositions suitable for use in the manufacture of cured-in-place gaskets (CIPGs), silicone elastomers resulting from the cure of such compositions and methods for making CIPGs from such compositions. The inclusion of a compound having at least two trialkoxysilyl groups, at least two dialkoxyalkylsilyl groups or a mixture of two or more trialkoxysilyl groups, and dialkoxyalkylsilyl groups per molecule selected from: (i) (R10)z (R11)3-z Si—(W)—Si (R11)3-z (R10)z; or (ii) 1,3,5-tris[3-((R10)z(R11)3-z Si)-D]-1,3,5-triazine-2,4,6(1H,3H,5H)-trione where each R11 is independently an alkoxy group having 1 to 6 carbons; each R10 is independently R11 or an alkyl group having 1 to 6 carbons, z is 0 or 1; W is a linear or branched alkylene having 1 to 12 carbons; and D is an alkylene group having from 1 to 6 carbons; provides CIPGs which show both a good adhesion to aluminium and a good compression set.

Abstract: A hydrosilylation curable textile coating composition comprises: (a) a linear organopolysiloxane polymer having at least two alkenyl and/or alkynyl groups per molecule; (b) a reinforcing filler comprising at least one of fumed silica, precipitated silica, or calcium carbonate; (c) a linear trimethyl terminated polydimethyl methylhydrogen siloxane containing at least two silicon-bonded hydrogen groups per molecule; Ld) a hydrosilylation cure catalyst; (e) an organosilicon resin; and (f) an adhesion promoter comprising a mixture and/or reaction product of: (i) one or more alkoxysilanes having an epoxy group in the molecule; (ii) a linear organopolysiloxane oligomer containing at least one alkenyl group and at least one hydroxy or alkoxy group per molecule; and (iii) an organometallic condensation reaction catalyst comprising organoaluminum or organozirconium compounds. Air bags and air bag fabrics can be coated with the hydrosilylation curable textile coating composition, and the resulting air bags and fabrics generally have enhanced scrub resistance.

Abstract: Provided herein is a self-lubricating silicone elastomer composition and a self-lubricating, elastomeric material made therefrom which has a low coefficient of friction and avoids the need for “self-bleeding”. The self-lubricating silicone elastomer composition comprises: (i) 50 to 75% by weight of one or more polydiorganosiloxane polymer(s) containing from 0.01 to 0.1% by weight of alkenyl and/or alkynyl content; (ii) 3 to 15% by weight of a polydiorganosiloxane polymer having ≥0.5% by weight of alkenyl or alkynyl content; (iii) 10 to 35% by weight of reinforcing filler; and either or both of (iv) a peroxide catalyst; or (v) a hydrosilylation catalyst package.
