  • Patent number: 6831117
    Abstract: With the hardener particle of the present invention, because siloxane or an alkoxy group is bonded to a central metal located on a surface, an adhesive prepared by dispersing the hardener particles in an epoxy resin together with a silane coupling agent hardly causes reaction between the hardener particles and the silane coupling agent at ambient temperature whereby the preserving property of the adhesive is high. Because no siloxane is bonded to metal chelate or metal alcoholate at the part other than the surface of the hardener particles, the hardener particles are broken when the adhesive is heated, and the metal chelate and the metal alcoholate on the part other than the surface of the hardener particles reacts with the silane coupling agent to form cation, thereby polymerizing the epoxy resin with the cation to harden the adhesive even at low temperature within shorter time.

  • Patent number: 6824604
    Abstract: The invention relates to coloring pigment granulates and a method for producing the same. The aim of the invention is to provide a granulate and a method for economically producing the same. The granulate disintegrates very quickly once added to a building material that is to be colored. To this end, the granulates are comprised of granulate cores which do not contain binding agents, which have a granular size ranging from 0.1 to 8 mm and which are enclosed by an enveloping layer made of a material that can be broken down. In addition, the granulates have a moisture content <30% and the granulates that do not contain binding agents are produced in a pregranulator, are compacted immediately after granulation and are subsequently subjected to a screening process. Lastly, the useful granular fraction that has been separated out during the screening process is enclosed with an enveloping material.

  • Patent number: 6822020
    Abstract: Modified silica fillers are prepared by contacting silica with blends or mixtures containing diorganodihalosilanes and tetrahalosilanes in weight ratios of 1:0.1 to 1:2, respectively. While dialkyldichlorosilanes and tetrahalosilanes such as dimethyldichlorosilane and silicon tetrachloride, respectively, are most preferred, the blends or mixtures may also comprise compositions containing other silanes such as mercaptopropyltriethoxysilane.

  • Publication number: 20040229040
    Abstract: Spherical silica-titania-based fine particles surface-treated with silane are provided. The fine particles have a titanium atom content of 0.001 to 5% by weight, a frictional electrification with iron powder of −100 to −300 &mgr;C/g, a bulk density of 0.2 to 0.4 g/ml, and a particle diameter of 0.01 to 5 &mgr;m. The particles are useful as a material for an external additive for an electrostatically charged image developing toner. The toner is unlikely to cause degeneration or scratching of organic photoreceptors, displays excellent dispersibility and favorable flowability and consequently does not cause adhesion to the photoreceptor.
