    摘要： A process for producing a hardenable composition with high storage stability containing scaly silica particles which consist essentially of foliar secondary silica particles and have a laminated structure, said process comprising: (1) a step of subjecting a silica sol, a silica hydrogel or hydrous silicic acid to hydrothermal treatment in the presence of an alkali metal salt to form tertiary agglomerated particles of the scaly silica in the form of porous three-dimensional disorderly agglomerates of foliar secondary silica particles, each secondary particle being formed by a parallel face-to-face alignment of a plurality of flaky primary particles which are overlaid one on another, and (2) a step of disintegrating and dispersing the tertiary agglomerated particles of silica in an organic polymer in the form of an aqueous emulsion by a wet method.

    摘要： To provide a stable water-repellent inorganic powder which is substantially free from re-dissolution of a silicon compound used for surface treatment whether an organic solvent is polar or non-polar.A water-repellent inorganic powder which is surface-treated with a silicon compound, wherein the silicon compound is one having a group reactive with the inorganic powder, and when the inorganic powder is dispersed in any of polar organic solvents and non-polar organic solvents, the retention of the silicon compound is at least 90%. Preferably, the silicon compound is an aqueous emulsion of any of methylhydrogen silicone oil, alkoxy-modified silicone oil, amino-modified silicone oil, epoxy-modified silicone oil, polyether-modified silicone oil or carboxyl-modified silicone oil, and to the aqueous emulsion, at least one surfactant selected from the group consisting of a sorbitan fatty acid ester type, a polyoxyethylene sorbitan fatty acid ester type, a polyethylene glycol fatty acid ester type, a polyoxyethylene fatty acid ester type, an N-acylamino acid type, a polyoxyethylene alkyl ether type and a polyoxyethylene alkylphenyl ether type, is incorporated.
