Abstract: A process of spraying a polymeric compsn. to form a spray of finely atomised liq. droplets comprises (1) forming in a closed system a liq. mixt. a temp. T0 comprising: (a) a non-volatile fraction contg. at least one polymer that is cable of being sprayed; and (b) a solvent fraction that is partially miscible with (a) and contains an amt. of at least one compressed fluid sufficient, when it is added to (a); (i) to make the viscosity of the mixt. suitable for spraying; and (ii) to let the liq. mixt. form a liq. compressed fluid phase at temp. T0 the compressed fluid being a gas at 0 deg. C and 1 atmos. pressure; and (2) spraying the liq. mixt. by passing it at temp. T0 and spray pressure P, into an orifice, through which the mixt. flows to form a liq. spray, where spray pressure P1 is above the min. pressure P2 at which the liq. mixt. forms a liq. compressed fluid phase at temp. T0, thus passing the liq. mixt. through the liq.-liq. region of the polymer compsn. and compressed fluid during depressurisation.

Abstract: The present invention is directed to methods for spraying polymeric compositions with supercritical or subcritical compressed fluids such as carbon dioxide or ethane over a wider range of spray conditions to provide improved spray application quality with reduced emission of solvent. The methods are accomplished by using an elongated spray orifice to transform narrow, fishtail, liquid-film sprays to wider, feathered, decompressive sprays.

Abstract: A process which comprises (i) the generation of release surfaces by application to predetermined areas of a solid surface of a solution, suspension or dispersion of a release agent and a supercritical fluid that vaporizes from the release agent, (ii) the deposition of a mass onto the release surface containing the release agent, and (iii) the separation of the mass or a product derived from the mass from such surface covered by the release agent. Novel apparatus for carrying out the process are described.

Abstract: Disclosed are methods and apparatus for spraying liquid compositions by airless spray techniques so as to obtain wider spray patterns without having to alter the construction or configuration of conventional nozzles, nozzle tips or spray guns. By means of the present disclosure, the width of a spray pattern may be changed while the spraying operation is being conducted.

Abstract: The present invention relates to precursor adhesive coating compositions which optionally contain water, which are particularly suitable for being admixed with at least one supercritical fluid used as a viscosity reduction diluent and then spraying this resultant liquid mixture of supercritical fluid and precursor adhesive coating composition onto a substrate to be coated. Processes for spraying these precursor adhesive coating compositions are also disclosed.
