    摘要: A system for measuring a coating thickness on a target surface includes a terahertz spectroscopy device and a reference image projector. The terahertz spectroscopy device includes a radiation head that is operable to project a terahertz radiation beam onto the target surface and receive a reflected beam. The reference image projector includes a visible light device and is operable to project a reference image using the visible light device onto the target surface. A visual characteristic of the reference image indicates at least one of distance, rotational alignment, and angular alignment of the radiation head relative to the target surface.

    摘要: A wet on wet coating application method. The method includes contacting a polyol-containing layer including a polyol in an amount of 10 to 70 percent by weight and a isocyanate-catalyst-containing layer including an isocyanate and a catalyst to form a boundary layer between the layers being the reaction product of the polyol and isocyanate catalyzed by the catalyst and carried out at 68° F. to 75° F.

    摘要: A method of controlling application of material onto a substrate includes ejecting atomized droplets from an array of micro-applicators while the array of micro-applicators cyclically moves about at least one axis. The atomized droplets from each of the plurality of micro-applicators overlap with atomized droplets from adjacent micro-applicators and a diffuse overlap of deposited atomized droplets from adjacent micro-applicators is provided on a surface of the substrate. The array of micro-applicators cyclically rotates back and forth around the at least one axis and/or moves back and forth parallel to the at least one axis. For example, the at least one axis can be a central axis of the array of micro-applicators, a length axis of the array of micro-applicators, a width axis of the array of micro-applicators, and the like. Also, the array of micro-applicators can be part of an ultrasonic material applicator used to paint vehicles.
