<p>Method of coating a substrate with a water-based coating composition comprising: (a) applying a layer of the coating composition to the substrate to provide a coated substrate, (b1) humidifying an atmosphere surrounding the coated substrate with a sufficient amount of a water vapor or a water mist to retard evaporation of water from the coating layer on the substrate or (b2) cooling the coated substrate a sufficient amount to retard evaporation of water from the coating layer on the substrate; (c) allowing sufficient time for the coating composition on the coated substrate to flow and provide a coating of uniform thickness; (d) then removing water from the coating composition to dry the coating layer on the substrate. Apparatus for carrying out this process.</p> |
