Abstract
The present disclosure describes a method of inhibiting film or skin formation on exposed interior surfaces of containers of waterborne coating products without substantial contribution to volatile organic content of the coating composition, and describes the article with the coating composition having a reduced tendency for film or skin formation. The method involves applying to the coating composition in the container an aqueous mixture, comprising at least one surfactant with oxyalkylene moieties wherein the surfactant is essentially non-volatile and present in about up to 60 weight percent of the mixture. The article is a lidded container having the coating composition with a float on the composition's surface that is closest to the headspace within the container.
