Abstract:
The present invention relates to a coating composition including a film-forming resin present in an amount of 20 percent to 60 percent by weight of the total solids of the coating composition; an amount of a first material comprising a reflective property towards ultraviolet light; and an amount of a second material comprising an absorptive property towards ultraviolet light. A substrate comprising a surface at least partially coated with the coating composition. A method of preparing a substrate including coating a portion of a surface of the substrate with the coating composition and curing the coating composition. A vehicle comprising a surface at least partially coated with the coating composition.
Abstract:
Disclosed herein is a method of measuring edge sharpness of coating droplets deposited on a substrate. The method comprises selecting a maximum allowable droplet diameter for coating droplets deposited outside a target edge of the coating, selecting a maximum size distribution of the coating droplets deposited outside of the target edge of the coating, selecting a maximum surface edge roughness of a deposited edge of the coating, measuring an actual maximum droplet diameter of the coating droplets deposited outside the target edge of the coating and comparing the actual maximum droplet diameter with the maximum allowable droplet diameter, measuring an actual size distribution of the coating droplets deposited outside the target edge of the coating and comparing the actual size distribution with the maximum size distribution, and measuring an actual surface edge roughness of the deposited edge of the coating and comparing the actual surface edge roughness with the maximum surface edge roughness. Also disclosed herein is a method for controlling liquid coating droplets during deposition onto a substrate. The method comprises directing atomized liquid coating droplets in a flow path toward the substrate, and controlling at least one of droplet size, droplet size distribution, droplet flight path; droplet drift, and droplet splash.
Abstract:
The present disclosure is directed to a composite structure comprising at least one reinforced polymer layer comprising a reinforcing material; a layer comprising a metal substrate comprising a surface and a conformal organic coating present on at least a portion of the surface; wherein the layer comprising the metal substrate is in direct contact with the reinforced polymer layer, and the reinforcing material is more noble than the metal substrate. Also disclosed is a method of making a composite structure, a surfacing film, and a test method for evaluating the galvanic corrosion resistance of a metal substrate test piece.
Abstract:
The present invention is directed to a curable film-forming composition comprising: (a) a curing agent comprising reactive isocyanate functional groups; (b) a film-forming compound comprising functional groups reactive with the reactive isocyanate functional groups in (a); (c) a photo-latent catalyst; (d) a beta-diketone having a flash point higher than 60C (140 F); and (e) a beta-diketone having a flash point lower than or equal to 60C (140 F). The invention is further directed to methods of controlling the rate of cure and increasing the wet-edge time of a curable film-forming composition comprising an isocyanate functional curing agent, by adding to the curable film-forming composition a catalyst component comprising: (i) a photo-latent catalyst; (ii) a beta-diketone having a flash point higher than 60C (140 F); and (iii) a beta-diketone having a flash point lower than or equal to 60C (140 F).
