Silicone mold release compositions which are a stable blend of hydrophobic-modified organopolysiloxane and an aminoorgano- or mercaptoorgano-functional organopolysiloxane, or a solution in organic solvent of a stable or unstable blend, provide exceptional mold release properties while retaining paintability of molded parts.

Paintable organopolysiloxane mold release compositions and processes for their use

An organopolysiloxane adhesive contains an organopolysiloxane rubber base, an organopolysiloxane pressure sensitive adhesive, a aliphatic unsaturated-functional M&prime;Q resin, and a polyhydrido-functional organopolysiloxane in an organic solvent, and exhibits differential adhesion between dental impression material and dental impression tray material.

Dental adhesive and use thereof in preparing dental impression

Star- and comb-type branched organosilicon compounds containing .omega.-terminated organopolysiloxane branches are readily synthesized by the catalyzed or uncatalyzed reaction of an at least tris(organyloxy)-functional organosilicon compound with a predetermined amount of substantially linear minimally disilanol-functional organopolysiloxane. Well defined, non-resinous, liquid products of low viscosity may be obtained.

Process for preparing silanol-functional specifically branched

Asphalt release coatings are prepared by applying an aqueous emulsion containing an organopolysiloxane component, an effective amount of one or more emulsifying surfactants, and most minor amount of a multiple release additive. The compositions exhibit improved release, particularly multiple releases, even with polymer modified asphalt binders.

Asphalt release agents and use thereof

Aqueous textile treating compositions containing both nitrogen-functional organopolysiloxanes and oligomeric polyisobutylene polymers are as effective as conventional textile treating compositions containing only nitrogen-functional organopolysiloxane, and have improved resistance to yellowing, improved washfastness, and are more cost effective. Stable concentrates containing amino-functional organopolysiloxane, polyisobutylene, and a blend-stabilizing surfactant may be used to form aqueous emulsion and microemulsion fabric softener compositions.

Textile treating compositions comprising n-functional

The present invention relates to a wipe-on polish composition which contains no wax or abrasive components. The polish requires minimal effort to wipe out to a thin, glossy, streak-free, hydrophobic film. The polish is comprised of an emulsion that contains an organopolysiloxane and a volatile diluent.

Polish composition

Detergent resistant compositions comprising an aqueous emulsion of hydrocarbonoxy end-blocked branched organopolysiloxanes containing from 10 to 99 mol percent of R.sub.2 SiO units and from 90 to 1 mol percent of R.sub.3 SiO.sub.3/2 units and/or SiO.sub.4/2 units, where R is a monovalent hydrocarbon radical. Other silicone fluids such as aminofunctional, silicone fluids, organoalkoxysilanes, silicone resins, organopolysiloxane fluids and silicone gums as well as abrasive materials, surfactants and organic solvents may be incorporated in the aqueous emulsions.

Polymerizable .alpha., .beta.-unsaturated carbonyl-functional silicone compositions are obtained from the reaction of thiol-functional organopolysiloxanes with an .alpha., .beta.-unsaturated carbonyl-functional compound having at least two acryloyl or methacryloyl groups or mixtures thereof per molecule in the presence of a base catalyst. The .alpha., .beta.-unsaturatured carbonyl-functional silicone compositions may be combined with a photosensitizer and/or a free radical generator and polymerized by radiation and/or heat.
