LOW GLOSS METALLIC COLOR COATING

摘要

The present disclosure is directed to a process for producing a low gloss metallic color coating composition having a target gloss value. The low gloss metallic color coating composition can be produced from a high gloss metallic color coating composition with the addition of a matting agent. The disclosure is also directed to a coating system using the process. This disclosure is also directed to a method for matching color, flake appearance, and gloss of a coating. The processes, methods and systems of this disclosure are particularly useful for producing a low gloss metallic color coating composition having a target gloss value when the high gloss metallic color coating composition comprises both metallic effect pigments and color pigments.

1. A process for producing a low gloss metallic color coating composition having a target gloss value, said process comprising the steps of:
a) producing a first ratio of a matting agent and a first high gloss coating component based on a first gloss correlation function and said target gloss value, wherein said first gloss correlation function is associated with a plurality of measured gloss values and mixing ratios of said first high gloss coating component and said matting agent; and b) producing a second ratio of the matting agent and a second high gloss coating component based on a second gloss correlation function and said target gloss value, wherein said second gloss correlation function is associated with a plurality of measured gloss values and mixing ratios of said second high gloss coating component and said matting agent.
