ABSTRACT:
Disclosed herein is a process for a coating composition for application at extremely high pressures under conditions which significantly reduce the amount of volatile organic materials which are given off during the spray process. Preferably, the coating composition is based upon a plasticizer wet nitrocellulose lacquer. The composition is utilized in a spray process involving the filling of a spray pump receptacle with the coating wherein the spray pump is operated 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 150.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.
