Abstract
This disclosure is directed to a process for producing a target coating having two or more coating layers over a substrate. The disclosure is also directed to a primer coating composition comprising a topcoat component and one or more flatteners. This disclosure is further directed to a multi-layer coating formed by the process disclosed herein.
Claims18
A process for producing a target coating having two or more coating layers over a substrate and having a range of target gloss value, said process comprising the steps of:
- a) selecting a topcoat component based on said range of target gloss value;
- b) providing a first coating composition comprising said topcoat component and a first flattener component;
- c) applying said first coating composition over said substrate to form a first coating layer thereon;
- d) providing a second coating composition comprising said topcoat component, wherein said second coating composition is different in composition from said first coating composition in that said first coating composition comprises at least one additional component not present in said second coating composition, wherein said at least one additional component is selected from the group consisting of:
- catalysts and solvents;
- and
- e) applying said second coating composition over said first coating layer to form a second coating layer thereon.

- catalysts, solvents, pigments, UV stabilizers, wetting agents, leveling and flow control agents, rheological control agents, thickeners, and antifoaming agents;
- and
- e) applying said second coating composition over said first coating layer to form a second coating layer thereon.
