International Classification:

C08G 7704

US Classification:

10628712

Abstract:

A room temperature vulcanizable silicone rubber composition with sag-control wherein the base material or mixture of ingredients for forming the composition comprises a silanol end-stopped diorganopolysiloxane polymer, at least 3 parts of a fumed silica filler and as the sag-control ingredient, from 0. 03 to 2. 0 parts of a polyether. As a work-like extending additive in the case of a two-part room temperature vulcanizable silicone rubber composition, there may be added to the basic ingredients of the composition a low viscosity silanol end-stopped polysiloxane.

Assignee:

General Electric Company - Waterford NY

International Classification:

C08L 8306

US Classification:

260 37SB

Abstract:

A self-bonding room temperature vulcanizable silicone rubber composition comprising a silanol-terminated diorganopolysiloxane base polymer, a filler, a crosslinking agent selected from carboxyl functional silanes and hydrocarbonoxy functional silanes, a curing catalyst and as the self-bonding additive a silyl maleate or a silyl fumarate or a silyl succinate. In place of the foregoing silane self-bonding additives there may be utilized as a self-bonding additive, a maleate functional polysiloxane, a fumarate functional polysiloxane or a succinate functional polysiloxane.

International Classification:

C08L 8306

US Classification:

524864

Abstract:

A process for producing a shelf-stable catalyst component for a room temperature vulcanizable silicone rubber composition comprising (a) mixing a organopolysiloxane fluid with first from 1 to 15 percent by weight of the total amounts of the following ingredients (1) an alkyl silicate cross-linking agent (2) a catalytic promoter which is a tin salt and (3) a self-bonding additive which is nitrogen-functional self-bonding additive until there is a uniform mixture; (b) adding to the mixture from 10 to 250 parts of filler and mixing the ingredients to a uniform mixture wherein the mixture is heated at a temperature of at least 100. degree. C. for at least 1 hour so as to drive off moisture and form a stable base mixture and then adding to the stable base mixture the rest of the cross-linking agent, the catalytic promoter and the shelf-bonding additive to form a self-stable uniform mixture.

US Classification:

260 37SB

Abstract:

A low moisture vapor transmission rate room temperature vulcanizable silicone composition comprising a silanol end-stopped diorganopolysiloxane with optionally a reinforcing or extending filler, an alkyl silicate crosslinking agent or in the alternative a co-polymer composed of monofunctional and tetrafunctional units and a catalyst which is the metal salt of carboxylic acid such as dibutyl tin dilaurate where the improvement comprises having in such a composition from 75 to 150 parts by weight of a vapor barrier filler which is mica with optionally up to 30% by weight of said vapor barrier filler being talc, wherein the above concentration of filler is based upon 100 parts of the silanol end-stopped diorganopolysiloxane polymer. Also in the present invention there is envisioned as SiH Olefin platinum catalyzed composition which has the foregoing mica as a vapor barrier filler.
