SJVUAPCD 4610 - 1 4/17/03 RULE 4610 GLASS COATING OPERATIONS (Adopted May 16, 2002; Amended December 19, 2002; Amended April 17, 2003)

1.0 Purpose

The purpose of this rule is to limit the emissions of volatile organic compounds (VOCs) from the coating of glass products.

2.0 Applicability

The requirements of this rule shall apply to any major source that coats glass products with VOC-containing materials.

3.0 Definitions

3.1 Aerosol Coating Product: any pressurized coating product containing pigments or resins that dispenses product ingredients by means of a propellant, and is packaged in a disposable can for hand-held application.

3.2 Clear Coating: a colorless coating, which contains binders, but no pigment, and is formulated to form transparent film.

3.3 Coating: a material applied onto or impregnated into a substrate for protective, decorative, or functional purposes. Such materials include, but are not limited to, paints, varnishes, sealers, and stains.

3.4 Coating Application Equipment: any equipment used to apply coating to a substrate. Coating application equipment includes coating distribution lines, coating hoses, pressure-pots, spray guns, and hand-application equipment.

3.5 Curtain/Flow Coater: a type of coating application equipment that coats an object by flowing a stream of coating over the object and draining off any excess
coating.

3.6 Dip Coater: a type of application equipment that coats an object by submerging the object in a vat of coating, and subsequently withdrawing the object and draining off the excess coating.

3.7 Electric Dissipating Coating: a coating that rapidly dissipates a high-voltage electric charge.

3.8 Electrostatic Application: a method of applying coating whereby atomized paint droplets are charged and subsequently deposited on the substrate by electrostatic

attraction.SJVUAPCD 4610 - 2 4/17/03 3.9 Grams Of VOC Per Liter Of Coating, Less Water and Less Exempt Compounds: a weight of VOC per combined volume of VOC and coating solids and can be calculated by the following equation:

Grams of VOC per Liter of Coating, Less Water and Less Exempt Compounds = Ws - Ww - Wec

Vm - Vw - Vec

Where: Ws = weight of volatile compounds in grams Ww = weight of water in grams Wec = weight of exempt compounds in grams

Vm = volume of material in liters

Vw = volume of water in liters Vec = volume of exempt compounds in liters

3.21 Roll Coater: a type of coating application equipment that utilizes a series of mechanical rollers to form a thin coating film on the surface of a roller, which is then applied to a substrate by moving the substrate underneath the roller.

3.22 Shock-Free Coating: a coating applied to electrical components to protect the user from electric shock. The coating has characteristics of being of low capacitance and high resistance, and having resistance to breaking down under high voltage.

3.23 Stencil Coating: an ink or a coating which is rolled or brushed onto a template or stamp in order to add identifying letters and/or numbers.

3.24 Touch-up Coating: a coating used to cover minor imperfections appearing after the main coating operation.

3.25 Translucent Coating: a coating, which contains binders and pigment, and is formulated to form a colored, but not opaque, film.

3.26 Two-component Coating: a coating requiring the addition of a separate reactive resin, commonly known as a catalyst, before application to form an acceptable dry film.
