    Abstract: High solids coating methods and apparatus are disclosed which eliminate many of the disadvantages associated with known coating processes. The techniques disclosed require only a minor amount of a volatile solvent to achieve atomization and application of a paint or other coating material. High solids coating compositions containing about 70-99% by weight solids are atomized and coated. This method also enables polymeric compositions having high molecular weight to be employed as coating materials. According to techniques described, liquid compositions containing film-forming solids are kept under pressure with a minor amount of a highly volatile solvent of from about 1 to 30% by weight, even as low as about 1-10% by weight, at a temperature above the normal boiling point of the solvent. Such a composition is then atomized by releasing the pressure upon a stream of the composition at a temperature above the normal boiling point of the solvent and below the minimum foam temperature at atmospheric pressure for the composition. The film-forming solids are thus conveyed with or without an external atomizing means.

    Abstract: A method is disclosed for keeping a part such as a motor vehicle body wet between preparation stations during preparation for painting by placing the part in an atmosphere of wet vapor. In one embodiment, the part is placed in an enclosure between preparation stations, into which enclosure saturated vapor at a pressure of about 3.5 bars is introduced. The pressure within the chamber is essentially ambient pressure so that the pressurized saturated vapor expands to ambient pressure in the enclosure.

    Abstract: A razor blade having a fluorinated polymer coating over its cutting edge and a method for its preparation. A hydrocarbon polymer is disposed on the cutting edge, which polymer after appropriate sintering is brought into contact with a fluorine-rich atmosphere resulting in replacement of a plurality of hydrogen atoms by fluorine atoms creating a multiplicity of (--CF.sub.2 --CF.sub.2 --) groups.

    Abstract: An improved process for laser or UV curing of pigmented-binder systems comprising ethylenically unsaturated polymers containing at least about 0.05 weight parts of opacifying pigment per weight part of binder wherein the pigmented-binder system includes from about 0.5% up to about 3% of a halogenated derivative of naphthalene in combination with about 0.1 to 2% aromatic amino carbonyl photosensitizers and from about 0.5% to 2% aromatic ketone or aldehyde photosensitizers. The sensitized binder system is a substantially improved system suitable for curing by ultraviolet or laser energy sources.
