A method of making a lithium alkylsiliconate composition comprising adding an alkylalkoxysilane to a first mixture comprising lithium hydroxide and water to form a second mixture comprising a lithium alkylsiliconate and an alcohol, wherein i) the mole ratio of lithium hydroxide to alkylalkoxysilane is from 0.9 to less than 1.1 and the water is from 89 to 93 mol %, or ii) the mole ratio of lithium hydroxide to alkylalkoxysilane is from 1.1 to 1.4 and the water is from greater than 93 to 99 mole %.

Lithium alkylsiliconate composition, coating, and method of making same

The invention relates to a process for preparing a cyclic siloxane copolymer, a water repellent composition and the use for treating porous substrates like concrete, especially reinforced concrete.

Process of preparing a siloxane copolymer

The invention provides a water repellent composition for treating porous substrates comprising an emulsion which includes water, at least one surfactant, and a siloxane copolymer having the formula (I) wherein R is an alkyl radical having 1 to 3 carbon atoms; a has a value of from 1 to 12; R' is an alkyl radical having 8 to 12 carbon atoms, b&#x2267;2; (a+b) is at least 5. This composition shows a good depth of penetration of porous substrates especially reinforced concrete and has a low Volatile Organic Content to ASTM D 5095. 

Water repellent for concrete

A process for preparing a cyclic siloxane copolymer, a water repellent composition and the use for treating porous substrates like concrete, especially reinforced concrete.

An aqueous emulsion for waterproofing a surface comprising:

Aqueous emulsions of alkylalkoxysilanes

Aqueous silicone emulsions are disclosed containing a phenyl silsesquioxane resin, an alkoxysilane, a hydroxy terminated polydialkylsiloxane, and an emulsion of an aminofunctional polysiloxane. The silicone emulsions are useful for imparting water repellency to various surfaces, and in particular, inorganic building surfaces.

Aqueous silicone emulsion for imparting water repellency

A method of improving the release and antideposition characteristics of a hard impermeable surface. A hard impermeable surface is coated with a film of an aqueous solution. The solution is formed by combining (i) a dimer of at least two alkoxy functional silanes, (ii) an aqueous silicone emulsion of a polydiorganosiloxane, and (iii) water. The film is allowed to dry on the hard impermeable surface or the film can be wiped to dryness. The solution may also contain a water soluble hydrophilic solvent such as propylene glycol.

Silicone release agent and method

A composition is formed by combining water with an organic polymer such as polybutylene or an alkyd resin, and an alkoxysilane of the formula R.sub.n Si(OR').sub.4-n where R is an alkyl radical of 1-10 carbon atoms, an alkenyl radical having 2-8 carbon atoms, phenyl, chloropropyl, or trifluoropropyl, n is 1 or 2, and R' is an alkyl radical having 1-6 carbon atoms. The composition is free of amine or quaternary ammonium functional silanes. It can be emulsified and used to treat a cellulosic or masonry surface to render it water repellent.

Water repellent composition

Hard surfaces are polished by applying an abrasive free, preferably clear, composition formed from an aqueous phase and a silicone phase. The aqueous phase contains water and a water soluble hydrophilic organic solvent. The silicone phase contains a volatile methyl siloxane, a siloxane polyether, and an organosilicon resin.

Self-leveling silicone polish

A polish formulation containing as components thereof at least one member selected from the group consisting of waxes, solvents, surfactants, film formers, abrasives and other ingredients normally used in making polishes. The improvement resides in incorporating into the polish formulation as a film former a silylated polycycloaliphatic amine or epoxide.

Polish containing silylated derivatives of organic amines and epoxides

A polish formulation containing as components thereof at least one member selected from the group consisting of waxes, solvents, surfactants, thickening agents, abrasives, dyes, odorants and other ingredients normally used in making polishes. The improvement resides in incorporating into the polish formulation a derivatized amine functional organosilicon compound.

Polish containing derivatized amine functional organosilicon compounds

A polish formulation containing as components thereof at least one member selected from the group consisting of waxes, solvents, surfactants, thickening agents, abrasives, dyes, odorants and other ingredients normally used in making polishes. The improvement resides in incorporating into the polish formulation a novel reactive amine functional silicone polymer.
