US 2014/0193571 A1 · LOW GLOSS METALLIC COLOR COATING

Abstract

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.

Dependent claims

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.

A process for producing a low gloss metallic color coating composition having a target gloss value from a high gloss metallic color coating composition, said high gloss metallic color coating composition comprising a binder component, one or more metallic effect pigments and one or more color pigments, said process comprising the steps of:

(A) identifying a first high gloss coating component comprising a first binder component and said one or more metallic effect pigments, but free from said one or more color pigments;
(B) identifying a second high gloss coating component comprising a second binder component and said one or more color pigments, but free from said one or more metallic effect pigments;
(C) producing a first ratio of a matting agent and said 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;
(D) producing a second ratio of the matting agent and the 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;
(E) producing a target amount of the matting agent based on the first ratio, the second ratio, and a predetermined target amount of the low gloss metallic color coating composition;
and
wherein, said binder component, said first and said second binder components are the same or compatible to each other.

A method for producing a matching coating layer to match flake appearance characteristics, color characteristics, and a target gloss value of a target coating, said method comprising the steps of:

(a) obtaining the flake appearance characteristics, the color characteristics and the gloss value of the target coating;
(b) retrieving at least one matching formula from a color database based on the flake appearance characteristics and the color characteristics, said matching formula comprises data for one or more binder components, one or more metallic effect pigments and one or more color pigments;
(c) obtaining a first gloss correlation function associated with a plurality of measured gloss values and mixing ratios of a first high gloss coating component and a matting agent, said first high gloss coating component comprising a first binder component and said one or more metallic effect pigments, but free from said one or more color pigments;
(d) obtaining a second gloss correlation function associated with a plurality of measured gloss values and mixing ratios of a second high gloss coating component and said matting agent, said second high gloss coating component comprising a second binder component and said one or more color pigments, but free from said one or more metallic effect pigments;
(e) producing a first ratio of the matting agent and said first high gloss coating component based on the first gloss correlation function and said target gloss value, and a second ratio of the matting agent and the second high gloss coating component based on the second gloss correlation function and said target gloss value;
and
(f) producing a target amount of the matting agent based on the first ratio, the second ratio, and a predetermined target amount of a target coating composition;
and
wherein, said first and said second binder components are the same or compatible to each other.
