A production method including the steps of applying the material Y onto a surface of the A layer, to form a layer of the material Y; and curing the layer of the material Y.

Superabsorbent mixtures M comprising at least 70% by weight of superabsorbent A having a liquid absorption of 20 g/g (T20) of less than 300 s and/or a volumetric liquid absorption under pressure 0.3 psi (2.07 kPa) (VAUL) with a τ value of less than 400 s, and at least 5% by weight of superabsorbent B having a centrifuge retention capacity (CRC) of at least 30 g/g.

The preparation of monodispersed TiO.sub.2 nanocrystals with nanocrystal size between 1-30 nm is described herein. These TiO.sub.2 nanocrystals are used to prepare dispersions into solvents, formulation into monomers, oligomers, and polymers, and nanocomposites from the resulting formulations. Dispersions of nanocrystals can be formed in various solvents at high loading, high transmittance, and low viscosity. Formulations incorporating these nanocrystals and a matrix material are highly stable, where the resulting nanocomposites have high refractive index and are optically transparent in the visible wavelengths, with very little or no scattering.

This disclosure relates to a dielectric film forming composition that includes a plurality of (meth)acrylate containing compounds, at least one fully imidized polyimide polymer, and at least one solvent.

A catalyst system comprising a combination of a tin-based moisture-cure catalyst, a titanium(IV) compound that is titanium dioxide or a titanium alkoxide, and zinc oxide. A catalyst masterbatch comprising the catalyst system and a carrier resin. A moisture-curable prepolymer formulation comprising the catalyst masterbatch and a (hydrolyzable silyl group)-functional polyolefin prepolymer. Methods of making and using same. Cured polymer products made therefrom. Articles containing or made from same.

A water-absorbent resin (21) has a shape in which a plurality of particles (40) having a substantially spherical shape is connected in a chain shape.

The present application discloses a method for making a rubber blade. The method includes applying a first coating composition and a second coating composition in separate steps on at least a part of a surface of a polyurethane elastic substrate; and solidifying the first coating composition and the second coating composition by ultraviolet light irradiating to form a hardened layer on the surface of the polyurethane elastic substrate. The first coating composition includes an isocyanate-group-terminated polyisocyanate and a first solvent. The second coating composition includes a first monomer, a photoinitiator, and a second solvent. The first monomer is at least one of an acrylate monomer and a methacrylate monomer each having an reactive hydroxyl group. The isocyanate group of the polyisocyanate is reacted with the reactive hydroxyl group of the first monomer to generate a urethane group to form a polyurethane acrylate. The present application also discloses a rubber blade.
