    Abstract: The present invention provides an inorganic-organic hybrid material having both the characteristics of the inorganic material and the characteristics of the organic material. The material has a lamellar structure formed by piling a sheet of silicon tetrahedrons upon a sheet of titanium octahedrons. In this lamellar structure, an organic group is bonded to a center atom of a tetrahedron via a covalent bond. The organic group can be polymerized to make the organic phyllotitanosilicate a tough and hard coating material. The hybrid material of the present invention thus has both the characteristics, such as high hardness and heat resistance, of the constitutive inorganic material and the characteristics, such as flexibility and filmability at room temperature, of the constitutive organic material, and further has an excellent UV-blocking property.

  • Patent number: 5708069
    Abstract: The present invention is hydrophobic silica gels and a method for their preparation under neutral conditions. The method comprises two steps, where in the first step the pH of a silica hydrosol is adjusted with a base to within a range of about pH 3 to pH 7 to facilitate formation of a silica hydrogel. In the second step the silica hydrogel is contacted with an organosilicon compound in the presence of a catalytic amount of a strong acid to effect hydrophobing of the silica hydrogel. In a preferred method, in a third step the hydrophobic silica gel is contacted with a sufficient quantity of a water-immiscible organic solvent to convert the hydrophobic silica hydrogel into a hydrophobic silica organogel.

  • Patent number: 5684113
    Abstract: A curable organopolysiloxane composition that maintains flowability under moisture-free and light blocking conditions, more rapidly forms a nonflowable adhesive when irradiated with high energy beams such as ultraviolet rays and electron beams, and forms an elastic body by further curing when exposed to atmospheric moisture. It also involves a method for adhering a substrate to an adherend using the composition. The curable organosiloxane composition has a viscosity of 3,000 Pa.s or less and is made up of a silicone resin containing no alkenyl groups, a polydiorganosiloxane having terminal units containing a mercapto group, an alkenyl-containing organopolysiloxane, and a condensation-reaction-promoting catalyst. An assembly which has a substrates adhered to an adherend is made by spreading the composition on the substrate, irradiating it with a high energy beam, contacting the irradiated surface with an adherend, and letting it stand in air, so that the substrate is adhered to the adherend.
