Vapor coating method
First Claim
1. A method of forming a coating on at least a portion of a surface of a substrate, comprising the steps of:
- (a) causing a stream of a carrier gas to collide with a stream of a fluid composition said colliding occurring at a carrier gas velocity substantially higher than the fluid stream velocity, the ratio of carrier gas velocity to fluid stream velocity being sufficient to cause vaporization of substantially all of the fluid composition to form a vapor having a condensation temperature;
(b) causing the vapor to flow to the surface of the substrate, said surface being at a temperature below the condensation temperature of the vapor; and
(c) condensing the vapor as a liquid on the surface to form the coating.

Abstract
Coating system and method that allows coatings to be formed from a wide variety of coatable compositions that are entirely free of any solvents or, alternatively, have relatively little solvent in minor amounts effective to help dissolve one or more components of such compositions. A fluid composition is atomized and contacted with a carrier gas. The contacting occurs under conditions such that vaporization of substantially all of the atomized fluid composition occurs so as to form a vapor having a condensation temperature. The vapor is caused to flow to the surface of the substrate. The surface is at a temperature below the condensation temperature of the vapor. Consequently, the vapor condenses onto the surface to form the coating.
