Section 096-129-2 - Definitions

(1) Air-dried coating. "Air-dried coating" means a coating that is dried by the use of air or forced warm air at temperatures up to 90 degrees Celsius (C) (194 degrees Fahrenheit (F)).

(2) Baked coating. "Baked coating" means a coating that is cured at a temperature at or above 90 degrees Celsius (C) (194 degrees Fahrenheit (F)).

(3) Coating. "Coating" means a material applied in a thin layer to a surface as a protective, decorative, or functional film. This term often refers to paints such as lacquers or enamels, but also refers to films applied to other materials such as varnishes, sealants, adhesives, inks, maskants, and temporary protective coatings. Such materials include, but are not limited to, paints, varnishes, sealants, adhesives, inks, maskants, and temporary protective coatings.

(4) Coating unit. "Coating unit" means a series of one or more coating applicators and any associated drying area or oven wherein a coating is applied, dried, or cured. A coating unit ends at the point where the coating is dried or cured, or prior to any subsequent application of a different coating. A surface coating operation does not require an oven or flashoff area in order to be included in this definition.

(5) Control device. "Control device" means equipment used to reduce, by destruction or removal, the amount of air pollutant(s) in an air stream prior to discharge to the ambient air.

(17) Web coating line. "Web coating line" means all of the coating applicator(s), drying area(s), or oven(s), located between an unwind station and a rewind station, that are used to apply coating onto a continuous strip of substrate (the web). A web coating line need not have a drying oven in order to be included in this definition.

(1) Can. "Can" means any cylindrical, single-walled container, with or without a top, cover, spout, or handle, that is manufactured from metal sheets thinner than 29 gauge (0.0141 inch (in)).

(3) End sealing compound coat. "End sealing compound coat" means a compound applied onto can ends that functions as a gasket when the end is assembled onto the can.

(4) Exterior basecoat. "Exterior basecoat" means a coating applied to the exterior of a two-piece can body to provide protection to the metal, or to provide background for any lithographic or printing operation.

(5) Interior body spray coat. "Interior body spray coat" means a coating applied to the interior of the can body to provide a protective film between the product and the can.

(6) Over varnish. "Over varnish" means a coating applied directly over a design coating or directly over ink to reduce the coefficient of friction, to provide gloss, and to protect the finish against abrasion and corrosion.

(7) Sheet basecoat. "Sheet basecoat" means a coating applied to metal in sheet form to serve as either the exterior or interior of two-piece or three-piece can bodies or can ends.

(8) Side-seam spray coat. "Side-seam spray coat" means a coating applied to the seam of a three-piece can.

(9) Three-piece can. "Three-piece can" means a can that is made by rolling a rectangular sheet of metal into a cylinder that is soldered, welded, or cemented at the seam with two ends attached.

(10) Two-piece can. "Two-piece can" means a can whose body and one end are formed from a shallow cup and to which the other end is later attached.

(11) Two-piece can exterior end coat. "Two-piece can exterior end coat" means a coating applied by roller coating or spraying to the exterior end of a two-piece can to provide protection to the metal.

(1) Fabric coating line. "Fabric coating line" means a web coating line where coating is applied to fabric. A fabric printing line engaged in the dyeing and finishing of textiles as classified in Industrial Group 226 or Industry 2231 is not considered a fabric coating line.

(2) Fabric coating unit. "Fabric coating unit" means a coating application station and its associated flashoff area, drying area, or oven wherein coating is applied and dried or cured in a fabric coating line. A fabric coating line may include more than one fabric coating unit.
