ABSTRACT:
A method and apparatus is provided for combining two components to form a coating material formulation in which one of the components is a "high volume" component comprising a resin including supercritical fluid as a diluent, and the other of the components is a "low volume" component, such as a catalyst. The relative ratio of resin to catalyst is controlled by adjusting the catalyst pressure as a function of the pressure at which the resin is supplied to ,one or more coating dispensers and by adjusting the duty cycle of a catalyst valve within the catalyst flow path.
