Abstract
A method and apparatus for spraying adhesive compositions having a high solids content comprises a source of supercritical fluid diluent such as supercritical carbon dioxide, a source of virgin adhesive, an adhesive dispenser and a mixer communicating with each source of material and with the dispenser. The mixer includes a dynamic mixing element which agitates the viscous adhesive material allowing the supercritical carbon dioxide to be effectively dispersed into the adhesive, thus forming an adhesive composition with a high solids content having a relatively low viscosity suitable for spray application of the adhesive.
