METHOD AND APPARATUS FOR FORMING A PERMANENT FOAM COATING BY ATOMIZATION ONTO A SUBSTRATE |
摘要 |
A method of atomizing a high solids viscous composition onto a substrate and foaming the composition comprising mixing a coating composition with a gas foaming 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 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. |
