Abstract

Presently described are components of a spray application system. At least one component comprises a liquid repellent surface layer. The liquid repellent surface (e.g. layer) may comprise a porous layer and a lubricant impregnated into pores of the porous layer; a fluoropolymer; a fluorochemical material and an organic polymeric binder; or a fluorochemical material melt additive and a thermoplastic polymeric material component. The component is typically a liquid reservoir, a liquid reservoir liner, a lid for a liquid reservoir or liner, or a combination thereof. In some embodiments, the component comprises a thermoplastic polymeric material. In some favored embodiments, the component is a removable liquid reservoir or liner. In some favored embodiments, the component is a collapsible liquid reservoir or liner. The spray application system typically further comprises a gravity-fed spray gun. Also described are spray application systems, methods of using a spray application system, as well as methods of making a component of a spray application system wherein the component has a liquid repellent surface.
