There is provided herein an opaque one-part room temperature vulcanizing silicone polymer composition comprising: (a) a silanol-terminated diorganopolysiloxane, (b) an opaque reinforcing filler; (c) a polyalkoxysilane crosslinking agent; (d) a condensation cure catalyst; (e) an organo-functional alkoxy silane adhesion promoter; and, (f) a cyclic siloxane. There is also provided a method for the continuous production of such a silicone polymer composition, and a paint containing such a silicone polymer composition.

Silicone coating composition containing surface sheen modifier

There is provided herein a one-part, moisture-curable, elastomeric, translucent coating composition comprising:

Moisture-curable, elastomeric, translucent silicone waterproofing coating and method of making the same

This invention relates to moisture-curable resins generally and, more particularly, to two-part moisture-curable resin compositions the first part of which contains a moisture-curable silylated resin and the second part of which contains water. The invention further relates to adhesive, sealant and coating compositions based on such two-part moisture-curable resin compositions.

Two-part moisture-curable resin composition and adhesive, sealant and coating compositions based thereon

A curable resin composition comprising an oxyalkylene base copolymer having at least one silicone atom containing group to the silicone atom of which a hydroxyl group and/or hydrolyzable group is attached and which is cross-linked through formation of a siloxane bond.

Moisture curable sealants

A silicone sealant composition containing: (a) a moisture curable organopolysiloxane component, comprising a mixture or reaction product of (i) an organopolysiloxane polymer having hydrolyzable substituent groups and (ii) a polyfunctional silicon compound having two or more hydrolyzable substituent groups, (b) a filler and (c) a hydrocarbon fluid comprising, based on 100 parts by weight of the hydrocarbon fluid, greater than 40 parts by weight cyclic paraffinic hydrocarbons and less than 60 parts by weight noncyclic paraffinic hydrocarbons, exhibits improved tensile, elongation and adhesive properties.

Room temperature curable silicone sealant

A low VOC primer composition suitable for use with room temperature vulcanizable silicones, comprising a polyorganosiloxane resin, an acrylic resin, an organotitanate, a silane or partial hydrolyzate thereof and an organic liquid in amount effective to dissolve the other components of the primer composition that provides improved adhesion to diverse substrates.

Adhesion primer for use with RTV silicones

One-part alkoxy curing room temperature vulcanizable silicone compositions comprising the bi-functional compounds containing the 1-sila-azacyclopentane structure wherein the compounds function as alcohol scavengers in one-part alkoxy curing room temperature vulcanizable silicone compositions and the alcohol reaction products of these compounds function as adhesion promoters in such room temperature vulcanizable compositions.

Neutral cure one component room temperature vulcanizable silicone

Silicon compounds containing the 1-sila-azacyclopentane structure function as alcohol scavengers in one-part alkoxy curing room temperature vulcanizable silicone compositions and the alcohol reaction products of these compounds function as adhesion promoters.

Bi-functional siloxane compounds

A primer comprising an organotitanate and an epoxysilane, when applied to a substrate, renders curable silicone compositions more adherent to a substrate after the silicone compositions have cured by increasing cohesive failure.

Primer composition for 1-part room temperature vulcanizable silicone

A standardized test for measuring the stringiness of room temperature vulcanizable silicone sealant compositions is disclosed wherein a tube of sealant is held at a constant angle to the surface upon which the sealant is being applied. The surface is movable and once a small bead of sealant has been deposited upon the surface the surface is moved at a constant rate of speed until the sealant bead breaks off from the source. The length of any string of sealant formed thereby is measured. This measurement for a given composition is compared to the measurement for other compositions and thereby allows optimization of sealant compositions to minimize an undesirable feature.

Process to measure the stringiness of room temperature vulcanizable

A non-corrosive translucent room temperature vulcanizable silicone composition consists essentially of an alkyl alkoxy stopped diorganopolysiloxane, a polyalkoxysilane crosslinking agent and a tetra alkyl titanate condensation cure catalyst.

Non-corrosive translucent RTV compositions

A room temperature vulcanizable silicone composition having an application rate greater than 150 g/min. and good thixotropy comprises an alkyl alkoxy stopped diorganopolysiloxane, a polyalkoxysilane crosslinking agent, a tetra alkyl titanate condensation cure catalyst, and 1,3,5-tris(alkoxysilylalkyl)isocyanurate.
