  • Publication number: 20250128286
    Abstract: A method includes applying a coating composition to a substrate through a high transfer efficiency applicator, wherein the coating composition comprises a polyamide wax; wherein the coating composition has a wet film thickness of at least about 30 microns measured at about 45 degrees without visible sag after cure, wherein the viscosity measured at a shear rate of about 1 s-1 recovers, after a high shear rate of about 10000 s-1 is applied for about 20 seconds, to within about 95% of a steady state viscosity achieved at greater than about 100 seconds of continuous shearing at about 1 s-1, in less than about 5 seconds; and wherein the coating composition has a complex viscosity measured at a temperature of about 60° C. that is reduced to from about 60 to about 500 mPa-s when the complex viscosity measured at about 30° C. is from about 800 to about 8000 mPa-s.

  • Publication number: 20230191450
    Abstract: Methods of coating a substrate are provided. In an exemplary embodiment, a coating composition is applied to the substrate with a high transfer efficiency applicator to produce a coating layer, where the high transfer efficiency applicator and the substrate remain spatially separate while the coating composition is applied. A droplet of the coating composition expelled from the high transfer efficiency applicator has a particle size of about 10 microns or greater. The coating composition has a viscosity of from about 1,000 to about 1,000,000 centipoise when the coating composition is subject to a shear rate of about 0.1 reciprocal seconds (s?1). However, the coating composition is non-Newtonian such that a coating composition viscosity decreases when the shear rate is increased to the coating composition. The coating layer is impinged with a gas such that a coating layer surface moves upon impingement with the gas.

  • Publication number: 20220332134
    Abstract: A method includes applying a coating composition to a substrate through a high transfer efficiency applicator to form the coating layer on the substrate wherein a loss of volatiles is less than about 0.5 weight, and wherein the coating composition comprises: A. a resin comprising an acrylic, a polyester, or combinations thereof; B. a melamine cross-linker; C. an optional pigment; D. an organic solvent; and E. at least one polyurea crystal sag control agent that is the reaction product of an amine and an isocyanate, that has a melting point of from about 50° C. to about 150° C., and that is present in an amount of from about 0.1 to about 4 weight percent based on a total weight of the coating composition; and wherein the coating composition has a wet film thickness of at least about 30 microns measured at about 45 degrees without visible sag.

  • Publication number: 20070157166
    Abstract: The present invention provides a system, method and software for programming and configuring an adaptive computing architecture or device. The invention utilizes program constructs which correspond to and map directly to the adaptive hardware having a plurality of reconfigurable nodes coupled through a reconfigurable matrix interconnection network. A first program construct corresponds to a selected node. A second program construct corresponds to an executable task of the selected node and includes one or more firing conditions capable of determining the commencement of the executable task of the selected node. A third program construct corresponds to at least one input port coupling the selected node to the matrix interconnect network for input data to be consumed by the executable task.

  • Publication number: 20040068716
    Abstract: The invention provides a compiler for generating assembly or configuration instructions from source code for an integrated circuit architecture of a plurality of different IC architectures. The source code is represented as a plurality of nodes of an abstract syntax tree. For each target architecture, a plurality of concrete instruction tiles are generated as concrete classes corresponding to and inheriting from a plurality of function tiles. Each function tile is implemented as an abstract class, represents a corresponding function, such as an ADD or MULT function, and implements a matching operation for the corresponding function. The compiler includes an instruction selector, formed as an abstract class, which implements a matching function and instruction generation for the abstract syntax tree by calling the corresponding matching operations of the concrete instruction tiles, inherited from the plurality of function tiles.
