Abstract
A method and apparatus for forming and dispensing a liquid coating material formulation or solution containing a nitrocellulose liquid coating composition and a supercritical fluid as a fluid diluent includes structure for combining the two components within a circuitous flow path or loop to form the coating material solution or formulation, while ensuring that the dissolved solids within the liquid coating composition do not precipitate and clog the supply of fluid diluent into the loop.
