Foam is a stable dispersion of a gas in a liquid medium that results when a surfactant layer forms around air bubbles and entrains them within it. Foams can be coated using a dip and nip coating process to apply a coating to the foam. Foam Coatings are defined as a polymer-modified, fiber-reinforced Portland cement based rigid coating used for rigid insulation panels, foam shapes, and insulated concrete form systems. Foam coatings include latex, PVC, acrylics, vinyl, activated carbon, and conductive carbon. Moreover, these coatings possess flame retardant and water-resistant properties and are increasingly used as colorants as well as surface coatings. Furthermore, they are widely applied on the surfaces such as primed wood, concrete block, primed fiberglass, papier mache, and muslin.
