摘要： A curable film-forming composition is provided that on curing produces a coating, comprising in a medium (i) 10 to 90 percent by weight based on the total weight of resin solids in the film-forming composition of a crosslinking agent; (ii) 10 to 90 percent by weight based on the total weight of resin solids in the film-forming composition of a polymer containing a plurality of functional groups reactive with the crosslinking agent; and (iii) 20 to 85 percent by volume based on the total volume of the film-forming composition of particles having a mean particle size less than 100 nm. The particles further have an index of refraction sufficiently similar to that of the polymer of (ii) to minimize haze, and have an affinity for the medium sufficient to keep the particles suspended therein. The affinity of the particles for the medium is greater than the affinity of the particles for each other, thereby preventing agglomeration of the particles within the medium. The film-forming compositions exhibit improved scratch (mar) resistance compared to compositions of the prior art, as well as improved sag resistance when compared to similar coating compositions prepared without the particles. A multi-component composite coating composition is also provided. The coating composition comprises a pigmented film-forming composition serving as a base coat and a clear film-forming composition serving as a transparent topcoat over the base coat. The transparent topcoat, or clear coat, is derived from the curable film-forming composition described above.

摘要： A method for producing ultrafine metal carbide particles and hydrogen is disclosed. The method includes introducing a metal-containing precursor and a carbon-containing precursor into a thermal reaction chamber, heating the precursors in the thermal reaction chamber to form the ultrafine metal carbide particles from the precursors and to form carbon monoxide and hydrogen, collecting the ultrafine doped metal carbide particles, converting at least a portion of the carbon monoxide to carbon dioxide and generating additional hydrogen, and recovering at least a portion of the hydrogen.

摘要： A crystalline colloidal array of particles is disclosed, which includes reactive surfactant covalently bound to the particle surfaces. During formation of the array, the bound surfactant remains in position on the particles resulting in reduced quantity of defects compared to arrays of particles produced with non-reactive surfactants.

摘要： A curable film-forming composition is provided comprising in a medium (i) 10 to 90 percent by weight based on the total weight of solids in the film-forming composition of a crosslinking agent; (ii) 10 to 90 percent by weight based on the total weight of solids in the film-forming composition of a polymer containing a plurality of functional groups reactive with the crosslinking agent; and (iii) at least 20 percent by volume based on the total volume of the film-forming composition of particles having a mean particle size less than 100 nm. A cured composition comprising the crosslinking agent of (i) and the polymer of (ii) has a cured softening point of less than 30° C. The particles of component (iii) further have a hardness value greater than 5 on the Moh hardness scale, and have an affinity for the medium sufficient to keep the particles suspended therein. The affinity of the particles for the medium is greater than the affinity of the particles for each other, thereby preventing agglomeration of the particles within the medium.Cured compositions having a film thickness of at least 5 microns demonstrate excellent chip resistance, superior sandability and resistance to scratching, water spotting and acid etch.
