Composition of comprising nano metal oxide/hydroxide particles and a polyorganosiloxane having increased refractive index, processes to cure these compositions for making transparent coats, shaped articles by an extrusion or molding process having a refractive index above the refractive index of the polyorganosiloxane. Use of the cured polyorganosiloxane compositions as optical devices, coats, lenses or light guides.

Provided are a method for preparing an organic/inorganic hybrid thermally conductive and insulating two-component adhesive and a method for using the same. The purpose is to solve the problem that thermally conductive adhesives in the prior art cannot meet the requirements of thermal conductivity, good bonding performance and insulation characteristics at the same time. The method includes: 1. preparing an organic phase aluminum dihydrogen phosphate; 2. treating a diamond thermally conductive filler; 3. modifying polyurethane compatible with aluminum dihydrogen phosphate; and 4. preparing an organic/inorganic hybrid insulating two-component adhesive. The use method includes: coating the adhesive onto a surface of a material to be bonded, and bonding; and subjecting a resulting member to be bonded to defoaming, heating, and holding.

A method for producing a radiation-sensitive resin composition includes a step 1 of putting at least a resin having a polarity that increases by an action of an acid, a photoacid generator, and a solvent into a stirring tank, and a step 2 of producing a radiation-sensitive resin composition by stirring and mixing the resin having a polarity that increases by the action of an acid, the photoacid generator, and the solvent in the stirring tank under a gas having an inert gas concentration of 90% by volume or more, in which in the step 2, an atmospheric pressure inside the stirring tank is higher than an atmospheric pressure outside the stirring tank, and in the step 2, a difference between the atmospheric pressure inside the stirring tank and the atmospheric pressure outside the stirring tank is 2.0 kPa or less.

A problem which is addressed is the provision of a method for manufacturing a wet rubber masterbatch that will serve as raw material for vulcanized rubber which excels in fatigue resistance, ability to achieve reduced heat generation, and tensile characteristics.

A wet rubber masterbatch is manufactured by means of a method comprising an operation in which a latex that has magnesium present therein in an amount which is not greater than 150 ppm is prepared; an operation in which a liquid mixture is made; and an operation in which the liquid mixture is coagulated to obtain a coagulum. The latex comprises rubber particles for which the 90 vol % particle diameter is not greater than 2 m. The operation in which the liquid mixture is made comprises a step in which the latex and a dispersion solvent are mixed together. The operation in which the liquid mixture is made further comprises a step in which a slurry that contains filler and a latex solution obtained as a result of the step in which the latex and the dispersion solvent were mixed are mixed together. The operation in which the coagulum is obtained comprises a step in which the coagulum is separated from waste liquid. The method for manufacturing the wet rubber masterbatch satisfies Formula I, below.

Plastisol compositions having a two-resin interpenetrating polymer network (IPN) are disclosed. The compositions begin with blocked isocyanate grafted acrylic polymer, blocked isocyanate urethane prepolymer, plasticizer, optionally pigment, and optionally thixotropic agent. When subjected to a thermal cure, the isocyanate groups on the acrylic polymer and urethane prepolymer both become unblocked and both react with the crosslinking agent to form an interpenetrating acrylic-polyurethane network. The two-resin IPN offers improved storage stability, hand-feel characteristics, and processing properties for textile printing among other uses. Preferably these plastisol compositions are essentially free of polyvinyl halides and phthalates restricted for regulatory reasons.
