Abstract:
The present invention is directed to fast dry ambient temperature curable coating compositions especially suited for use in automotive refinish applications. A binder component of the two pack coating composition includes an epoxy resin having at least one acetoacetate functionality and at least one epoxy group, and one or more reactive components provided with at least two acetoacetate functionalities. Some of the suitable reactive components include structured reactive diluent, an acrylic polymer, a polyester, or a combination thereof. A crosslinking component of the coating composition includes polyamine, a blocked polyamine or a mixture thereof. The present invention is further directed to a method of producing a coating on a substrate from the coating composition.

Silica-based low dielectric constant materials having three-dimensional network structures containing siloxane backbones which comprise SiO4 tetrahedron structural units, as well as their production and use. The materials can be applied as interlayer dielectrics for semiconductor elements and the like.
Abstract:
A method is provided for making a hydrophilic carbon fiber construction comprising the steps of: a) immersing a carbon fiber construction in an aqueous dispersion of one or more metal oxides, comprising: i) 1-15% by weight metal oxide; ii) 0.01%-5% by weight dispersant; and b) subsequently heating the carbon fiber construction sufficiently to remove substantially all of the dispersant. Typically the entire method can be completed in less than 20 minutes. In addition, a hydrophilic carbon fiber construction made according to the method of the present invention is provided, typically having a loading of metal oxide equivalent to 20-50 mg metal per gram of carbon.
Abstract:
A multifunctional thermochemically cured coating which provides noise reduction and weight reduction in combination with thermal insulating and corrosion resistant properties. The composition comprises an epoxy resin with a weight per epoxide of 175 to 950, a mixed methyl-phenyl hydroxyl functional silicone polymer, a catalyst, a silane, an anti-corrosive pigment, an inert film reinforcing pigment, calcium silicate fibers, a mixture of ground synthetic silicone rubber, silica, and fillers, and an organic solvent.
Abstract:
A process for glazing a chinaware article by forming a chinaware article having a bottom including a glazed foot and a dry foot. The glazed foot extends downwardly from the bottom to a point below the dry foot. A glaze is applied to the formed article so that the glaze is applied to the glazed foot and the dry foot is substantially free of the glaze. The article is supported on a supporting device so that the dry foot engages the device and the glazed foot is exposed. The article is heated to mature the article including the glaze. A glazed chinaware article is produced in the process.
Abstract:
An environmentally resistant coating (34) for improving the oxidation resistance of a niobium-based refractory metal intermetallic composite (Nb-based RMIC) at high temperatures, the environmentally resistant coating (34) comprising silicon, titanium, chromium, and niobium. The invention includes a turbine system (10) having turbine components (11) comprising at least one Nb-based RMIC, the environmentally resistant coating (34) disposed on a surface (33) of the Nb-based RMIC, and a thermal barrier coating (42) disposed on an outer surface (40) of the environmentally resistant coating (34). Methods of making a turbine component (11) having the environmentally resistant coating (34) and coating a Nb-based RMIC substrate (32) with the environmentally resistant coating (34) are also disclosed.
Abstract:
Dispersions in water of “poly{vinyl alcohol}” (“PVA”), preferably those types resulting from about 90 mole % hydrolysis and/or ester interchange of polymers of vinyl carboxylates and having a molecular weight of about 155,000, are particularly effective for modifying the surfaces of plastic materials to cause water and/or other specified liquids to spread more readily over the treated surfaces than over the untreated surfaces. A biocide to repress the growth of micro-organisms in the dispersions is preferred.
Abstract:
The present invention provides a nanoparticle dispersed structure featuring a polymer having a crosslinked structure that is chemically inert with respect to the nanoparticles and that is effective in suppressing diffusion, and provides a method for manufacturing this nanoparticle dispersion.
Abstract:
A process for the preparation of a coating layer comprising the steps: (a) applying a coating layer to a substrate from a coating agent of which the resin solids comprise a binder system curable by free-radical polymerization of olefinic double bonds, and containing 0.1 to 4 wt-%, based on resin solids, of a morpholin-2-one derivative sterically hindered by 3,3,5,5-polysubstitution as a light stabilizer; and (b) thermal curing of the applied coating layer.
