Abstract: Methods and apparatuses for forming linear nanoparticle arrays, and the nanoparticle formulations formed therewith, are described. The nanoparticle arrays may be incorporated into coating materials, and in one example may be provided at or near the surface of two-component polyurethane coatings for use in automotive refinish clear coats. Coatings incorporating such nanoparticles may be applied to a substrate under shear to cause the nanoparticles to arrange linearly.

Abstract: An aqueous, two component system for coating a substrate includes either a filler incorporated in both components prior to combining the components or an elevated amount of a filler, such as 50% by dry volume, in either component. The filler is preferably calcium carbonate, but may also be selected from titanium dioxide, sand, clay, mica, dolomite, silica, talc, perlite, gypsum, wallastonite, aluminum trihydrate, zinc oxide, barium sulfate, zinc sulfate, and combinations thereof. The first component includes a first polymer containing hydroxyl functional groups or amine functional groups and, optionally, a catalyst, preferably an organotin catalyst. The first polymer is selected from a polyester polyol, an acrylic polyol, a urethane polyol, a polyether polyol, a polyamine, an aldimine, a short oil alkyd, a silicone polyol, a cellulose ester, a vinyl polyol, and combinations thereof and preferably is a polyaspartic ester.

Abstract: A ceiling board coating composition includes water, a binder and a filler, said filler having large particles with an average particle size of a minimum of about 50 microns, medium particles with an average particle size in the range of from about 1.2 to about 30 microns, and small particles which have an average particle size in the range of from about 0.1 to about 1.0 microns.

Abstract: The flexibility of aminoplast wear layers is improved by the addition of a phyllosilicate. The concentration of the phyllosilicate is sufficiently low to not adversely affect other physical properties of the wear layer. The reduction or elimination of urethane improves stain resistance. The gloss level obtained for a given concentration of phyllosilicate depends on the particle size, and therefore type of phyllosilicate, as well as amount of phyllosilicate. A surface covering having areas of different gloss level can be obtained by printing areas forming the wear layer with compositions containing different types of phyllosilicates.
