A silsesquioxane resin wax composition, method for its preparation, and use in personal, household, automotive and medical care compositions are disclosed. The silsesquioxane resin wax can also find utility in a variety of oil and gas field applications, such as for crude oil wax control.

Silsesquioxane resin wax

A method for preparing dispersions of solid salts of fatty acids in low polarity liquids where a concentrated mixture of at least 50 percent of the solid salts of fatty acids in a low polarity liquid is subjected to high shearing forces, until the average particle size of the solid salts of fatty acids is less than 3 micron. The dispersion may then be diluted with the low polarity liquid to a lower concentration. The solid salt of the fatty acid is most preferably magnesium stearate, and the low polarity liquid is preferably a polydimethylsiloxane fluid having a viscosity of less than 100 centistoke (mm /s).

The discoloration of a non-acidic room temperature vulcanizable silicone sealant containing a ultraviolet radiation degradable fungicide is delayed by adding zinc oxide.

Sealants containing fungicides exhibiting less chromophoric development

The viscosity of a solvent is modified by thickening the solvent with a silicone latex. A silicone latex having a plurality of crosslinked polysiloxane particles is first prepared by mixing the siloxane polymer, a surfactant, and water; emulsifying the mixture to a gel phase; diluting the emulsion with water; adding a cure package (i.e., a catalyst, a crosslinker, or both, or a self catalytic crosslinker); and then without removing the water from the latex and after the particles of siloxane polymer in the latex have been cured, mixing the latex and solvent to thicken the solvent, forming viscous liquids, gels, and pastes. Water in the latex thickened solvent composition can be stabilized by adding a silicone polyether during mixing of the latex and the solvent. These stabilized latex thickened solvent compositions have beneficial properties such as clarity, shelf stability, and ease of preparation; and therefore have wide areas of application, especially as additives in antiperspirants, deodorants, and other personal care applications.

An aqueous silicone emulsion which upon the evaporation of the water forms a surface modified elastomeric silicone material providing improved coverage and adhesion of paint and reduced staining and coefficients of friction, each relative to other silicone elastomers from aqueous emulsions. The silicone emulsion comprises (A) water; (B) a plurality of particles dispersed in the water comprising a crosslinked product of a diorganosiloxane polymer; (C) a surfactant; and (D) an amount of an oxygen curing compound or a salt thereof effective for the surface modification. If a surface active salt of an oxygen curing compound is used, it may not be required to add additional surfactant in order to form the silicone emulsion.

The longevity of a surface driving oil layer on a room temperature vulcanizable silicone sealant is increased by adding zinc oxide to a non-acidic composition and exposing the composition to atmospheric moisture which forms the surface drying oil layer on an air exposed surface.

Enhanced longevity of surface drying oil on a sealant modified by

A sealant made from a room temperature curing polydimethylsiloxane composition has a siloxaphobic surface layer at the air-sealant interface where this layer is a fluorocarbon compound and a drying oil oxidation product. Elastomeric compositions made from polydimethylsiloxanes having both low reactivity endgroups and high reactivity endgroups and a siloxaphobic agent of fluorocarbon alcohol or a reaction product of the fluorocarbon alcohol and a hydrolyzable silane, are particularly useful for sealing buildings because they can withstand the expansions and contractions. One siloxaphobic agent is the reaction product between a fluorocarbon alcohol and a methyltri(methylethylketoximo)silane and the formula of one of the reaction product compounds is ##STR1## wherein x has an average value of at least 6.

A method produces a surface of a cured silicone elastomer with a hardened protective coating when an RTV silicone composition is blended with an oxygen curing compound, exposing the resulting composition to moisture to produce a cured dull surface, then applying a hardenable protective coating composition (such as paint) to the cured surface to obtain a flaw-free film, and then allowing the coating composition to harden.
