<p>A method of atomizing a high solids viscous composition (21) onto a substrate (27) and foaming the composition comprising mixing a coating composition with a gas foaming agent under elevated pressure and temperature. The coating composition (21) is airlessly atomized and projected onto a substrate (27). The gas remains dissolved in the coating after depositing on the substrate which causes the coating to foam after striking the substrate. The method provides a permanent foam coating composition with uniform cell distribution. The method is particularly suitable for foaming polymeric coatings such as plastisols and foods such as peanut butter or chocolate.</p> |
