Vapor coating method

A method of forming a coating on at least a portion of a surface of a substrate, comprising the steps of:

• (a) atomizing a fluid composition;
• (b) colliding the atomized fluid composition with a carrier gas, said colliding occurring at a carrier gas velocity substantially higher than the velocity of the atomized fluid, the ratio of carrier gas velocity to atomized fluid velocity being sufficient to cause vaporization of substantially all of the atomized fluid composition to form a vapor having a condensation temperature,
• (c) 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
• (d) condensing the vapor as a liquid onto the surface to form the coating.

A method of forming a polymeric coating on at least a portion of a surface of a substrate, comprising the steps of:

• (a) atomizing a fluid composition comprising one or more polymeric precursor components;
• (b) colliding the fluid composition with a carrier gas, said colliding occurring under conditions such that vaporization of substantially all of the atomized fluid composition occurs;
• (c) causing the vapor to flow to the surface of the substrate, which surface is at a temperature below the condensation temperature of the vapor;
• and
• (d) condensing the vapor as a liquid on the surface to form the coating.
