Abstract:
The present invention provides a paint composition including a primer and a finish paint. The primer includes a resin matrix, and a hydroxylated carbon nano-material admixed into the resin matrix. The hydroxylated carbon nano-material has a relatively high proportion of hydroxyl groups. The finish paint includes colloidal silica having a relatively high proportion of hydroxyl groups. The hydroxyl groups of the colloidal silica are capable of a dehydration reaction with the hydroxyl groups of the carbon nano-material at an interface between the primer and the finish paint. The present invention also relates to a coating structure including a priming coating and finish coating, and to a method for coating a substrate using the paint composition. The coating structure using the paint composition has good transparency and high mechanical strength.

Abstract:
A process for refining the visual image of the surface of an object, preferably roofing materials. The invention also relates to an application to the surface of an object, preferably for executing the process. An appearance of a copper coating on arbitrary surfaces, in particular roofing made of modern materials is possible, particularly with the inclusion of the patina appearance. The application according to this invention is particularly inexpensive and simple to apply and weather-resistant, especially when used in roofing. The process of this invention is distinguished since the surface is provided with a coat of an application medium containing copper particles which have been subjected to oxidation.

Abstract:
A glitter coating composition is applied from a manuallyoperated aerosol spray can by spraying a glitter coating composition comprising solid, highly reflectant, non-leafing polymer-coated metal flakes, a vehicle system therefor, and a propellant by the steps of (1) flowing the glitter coating composition through a passageway of substantially uniform crosssectional area, (2) expanding the flowing glitter composition in an elongated expansion chamber, and (3) accelerating the expanded flowing glitter composition through a constricted orifice. The glitter coating issues from the orifice in the form of a finelydivided well-mixed spray.
