Abstract

A liquid composition for rendering cellulosic materials non-adherent consists of an aqueous emulsion of a liquid organo-polysiloxane containing at least 1 per cent by weight of aluminium hydroxide or aluminium silicate, based on the organopolysiloxane and a water-soluble salt of titanium, zirconium, tin, lead, zinc or nickel in a quantity which provides at least 0.1 per cent by weight of the metal constituent of said water-soluble salt, based on the weight of organopolysiloxane. The organopolysiloxanes include those of the general formula <FORM:0792845/IV (a)/1> where R is a monovalent hydrocarbon radical x is from 1 to 1.5, y from 0.75 to 1.25 and x+y from 2 to 2.25; those of general formula <FORM:0792845/IV (a)/2> where a is not less than 3, e.g. polysiloxanes of formula <FORM:0792845/IV (a)/3> Water-soluble metal salts specified are zirconium tetrachloride, zirconium sulphate, zirconium oxychloride, zirconium nitrate, zirconium acetate, zirconium ammonium carbonate, zirconium oxybromide, stannous chloride, zinc acetate, zinc nitrate, nickel sulphate, nickel acetate, nickel chloride, titanium oxychloride, titanium nitrate, titanium oxalate, stannous gluconate or organic or inorganic complexes thereof. Dispersing or emulsifying agents, e.g. sulphonated condensation products of fatty acids with organic amines, sulphonated aromatic or alkyl aryl sulphonate derivatives and emulsion stabilizers, e.g. oleic acid may be added. In the examples: (1) a methyl polysiloxane was made by hydrolysing a mixture of trimethyl chlorosilane, methyl trichlorosilane, dimethyl dichlorosilane and mixed chloromethyl disilanes, the product being neutralized with sodium carbonate, filtered, stripped and mixed with water, oleic acid and an emulsifying agent to form a master emulsion which was mixed with water, sodium carboxy methyl cellulose, aqueous stannous gluconate and aluminium hydroxide to form a treating emulsion; (4) the master emulsion of Example (1) is mixed with stannous gluconate and an aluminium hydroxide gel; (7) as in Example (1) with the omission of the sodium carboxymethyl cellulose and the substitution of aluminium silicate for aluminium hydroxide. The treating emulsion are used for coating cellulosic materials, e.g. kraft paper, glassine paper, parchment paper, linen rag paper, regenerated cellulose, sulphite cellulose paper or sheeting or box materials. Specifications 575,667 586,187, [both in Group IV], 630,911, 632,955 and 745,156, [Group IX], are referred to.
