DEFINITION

Classification: 427/248.1

COATING BY VAPOR, GAS, OR SMOKE:

(under the class definition) Process under the class definition wherein a coating is produced on a base (i.e., substrate) by absorption of or condensation of, or reaction with, a vapor (mist), gas, or smoke.

(1) Note. This subclass provides for coating by placing a base in a chamber or reactor filled with mist or smoke. See SEE OR SEARCH THIS CLASS, notes below.

(2) Note. This subclass provides for reaction of a base or previously applied coating with a gas. However, it does not provide for decomposing a coating by heat and reacting it with a gas. See SEE OR SEARCH THIS CLASS, SUBCLASS, found below.

SEE OR SEARCH THIS CLASS, SUBCLASS:

69, for a vapor deposition process resulting in an electrical product having a fluorescent or phosphorescent base or coating.

74, for coating processes which result in a photoconductive product.

99, for making a printed circuit by vapor deposition.

124, for producing an electrical product by vapor depositing a metal coating material. 166, for vapor depositing on glass to make an optical element.

237, for coating the interior of a hollow article by vapor, gas, mist, or smoke.

226, through 229 for decomposing a coating which is on a base by heat and reacting the decomposition material with a gas.

421, through 427 for coating by spraying (i.e., projecting a

mist against a base).

587, through 590, for vapor deposition utilizing resistance heating.
