The present invention provides methods of making sticky powder comprising mixing one or more resin or (co)polymer powders in one or more mixing devices without agglomerating the powders and while measuring the power, work or torque drawn by the mixing devices, the mixing continuing until the measure of the power or torque drawn indicates that the powders have become sticky. The mixing further comprises adding to the powders one or more dry materials and mixing to so that the dry materials adhere or “bond” to the sticky powders. Alternatively, the methods further comprise slowing or stopping the mixing, or cooling while mixing once the said sticky powders have been formed, adding one or more dry materials to form a sticky powder mixture, and further mixing to bond the sticky powders and the dry materials together. The dry materials may comprise one or more flake materials, e.g. metallic flakes; layered pigments, clays, catalysts or antimicrobials; resins or (co)polymers; cyroprocessed materials, and materials encapsulated or dispersed in brittle materials. The methods may be automated.

A method for simulating the final finish of a multi-component finish material comprises submitting or receiving a request describing a desired single or multicolor surface appearance in a finish simulator to generate one or more simulated appearance samples, obtaining feedback on said simulated appearance sample and, if necessary, modifying said sample to simulate said desired surface appearance. The finish simulator comprises a library of finish templates that have been produced and software or processing means to apply rules to adjust the simulated finish for known changes in chemistry, composition, and application conditions. In addition, the appearance of an actual multicolor sample is reproduced by separating the sample into areas of different individual colors, identifying the individual color of each of said areas, translating said individual area colors into color values that correspond to those in a database of colors that have been produced, and searching the database for existing colors that are close matches for those in the sample. The final finish of the closely matching colors is preferably simulated and assessed electronically using a finish simulator. The method of the present invention reduces the total time necessary to generate a multi-component color finish to match a given sample and can eliminate the need for making trial finishes in assessing color finishes for matching.
