ABSTRACT:
A apparatus of atomizing a high solids viscous composition onto a substrate and foaming the composition comprising mixing a coating composition with a gas forming agent under elevated pressure and temperature. The coating composition is airlessly atomized and projected onto a substrate. The gas remains dissolved in the coating after depositing on the substrate which causes the coating to foam after striking the substrate. The apparatus provides a permanent foam coating composition with uniform cell distribution. The apparatus is particularly suitable for foaming polymeric coatings such as plastisols and foods such as peanut butter or chocolate.
