    Abstract: Disclosed herein is a process for preparing and applying a coating composition at extremely high pressures under conditions which significantly reduce the amount of volatile organic materials which are given off during the spray process. The spray process involves filling a spray pump receptacle with the coating wherein the spray pump is operable at pressures above about 2,750 psi and wherein the pump is provided with a temperature control means for assuring that the temperature of the pumped coating is in the range of about 65.degree. F. to 120.degree. F. so that the viscosity of the pumped coating is maintained in the range of about 250 to about 1,000 cps. The resulting coatings may be applied as a top coat, sealer, lacquer, etc. to any desired substrate, although wood is preferred, with the resulting finished coating being equal or superior to existing coating compositions.

    Abstract: A method for plasma treating a target surface of a part, including: obtaining the target surface on the part; placing the part in a chamber of a plasma generator; evacuating the chamber to a pressure of between 10-6 and 10 mbar; injecting a suitable gas into the chamber until a pressure in the chamber of between 10-4 and 102 mbar is reached; generating an electric current discharge within the chamber, via an electric generator, in order to generate a plasma; exposing the target surface of the part to the plasma for a predefined period of time depending on the power of the electric current discharge, on the gas injected into the chamber and on the material of the target surface, so as to deteriorate the surface condition of the target surface in order to increase the roughness thereof to make the target surface mat or more mat.
