LAST REVISED 03/02/92

(Adopted: March 2, 1992)

Rule 1114

Wood Products Coating Operations

(A) General

(1) Purpose The purpose of this Rule is to limit the

emission of volatile organic compounds from the coating

operation of wood products.

(B) Definitions

For the purposes of this rule, the following definitions

shall apply:

(1) "Adhesive" is any substance that is capable of bonding

surfaces together by attachment.

(2) "Aerosol-Spray Coating" is a coating which is sold in a

hand-held, pressurized, non-refillable container of

sixteen (16) ounces or less and which is expelled from

the container in a finely divided spray when a valve on

the container is depressed.

(3) "Binders" are non-volatile polymeric organic materials

(resins) which form the surface film in coating

applications.

(4) "Clear Topcoat" means a coating which contains resins

and binders but not opaque pigments and which is

specifically formulated to form a transparent or

translucent solid protective film.

(5) "Coating" is any coating applied on any wood stock

including, but not limited to, water repellent

preservative, semitransparent stains, opaque stains,

filler, clear topcoat; which is applied to a surface

and which forms a film in order to beautify and/or

protect such surface.

(6) "Coating Line" means automatic coating application

equipment, printing equipment, flash-off area, ovens,

conveyors, and other equipment operating in an

uninterrupted series for the purpose of applying

coatings, to wood flat stock.

(7) "Dip Coat" is to dip an object into a vat of coating

material and drain off any excess coating.

(8) "Flow Coat" is to coat an object by flowing a stream of

coating over an object and draining off any excess

coating.

(9) "Grams of VOC Per Liter of Coating Less Water and Less

Exempt Compounds" is the 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 - Wes

VOCg/L = -------------

Vm - Vw - Ves

Where: Ws = weight of volatile compounds in grams

Ww = weight of water in grams

Wes = weight of exempt compounds in grams

Vm = volume of material in liters

Vw = volume of water in liters

Ves = volume of exempt compounds in liters

(10) "Grams of VOC Per Liter of Material" is the weight of

VOC per volume of material and can be calculated by the

following equation:

Grams of VOC per Liter of Material:

Ws - Ww - Wes

VOCg/L = -------------

Vm

Where: Ws = weight of volatile compounds in grams

Ww = weight of water in grams

Wes = weight of exempt compounds in grams

Vm = volume of material in liters

(11) "High-Solids Stains" are stains containing more than 1

pound of solids per gallon by weight and can include

wiping stains, glazes, and opaque stains.

(12) "High-Volume Low-Pressure (HVLP) Spray" is to spray a

coating by means of a gun that operates between 0.1 and

10.0 psig air pressure, not to exceed 10 psig, measured

at the air cap of the coating application system, and a

permanent liquid coating pressure of not more than 50

psig.

(13) "Ink" is a fluid that contains dyes and/or colorants

and is used to make markings but not to protect

surfaces.

(14) "Low-Solids Stains" are stains containing 1 pound of

solids per gallon, or less, by weight.

(15) "Mold-Seal Coating" is the initial coating applied to a

new mold or repaired mold to provide a smooth surface

which, when coated with a mold release coating,

prevents products from sticking to the mold.

(16) "Opaque Stains" are all stains not classified as

semitransparent stains.

(17) "Panel" is a flat piece of wood or wood products,

usually rectangular, and used inside homes and mobile

homes for wall decorations.

(18) "Pigmented Coatings" are opaque coatings which contain

binders and colored pigments which are formulated to

hide the wood surface, either as an undercoat or

topcoat.

(19) "Reactive Diluent" is a liquid which is a VOC during

application and one in which, through chemical reaction

such as polymerization, 20 percent or more of the VOC

becomes an integral part of a finished coating.

For coatings that contain reactive diluents, the VOC

content of the coating is determined after curing. The

grams of VOC per liter of coating shall be calculated

by the following equation:

Grams of VOC/Liter of Coating Less Water and Less

Exempt Compounds =

Ws - Ww - Wes

-------------

Vm - Vw - Ves

Where:

Ws = weight of volatile compounds not consumed during

curing in grams

Ww = weight of water not consumed during curing in

grams

Wes = weight of exempt compounds not consumed during

curing in grams

Vm = volume of the material prior to reaction in liters

Vw = volume of water not consumed during curing in

liters

Ves = volume of exempt compounds not consumed during

curing in liters

(20) "Rate Per Day" is the amount applied between 12:00 a.m.

and 11:59 p.m. on the same calendar day.

(21) "Rate Per Calendar Year" is the amount applied between

12:00 a.m. January 1 and 11:59 p.m. December 31.

(22) "Repair Coating" is a coating used to re-coat portions

of a product which has sustained mechanical damage to

the coating following normal painting operations.

(23) "Roll Coater" is a series of mechanical rollers that

forms a thin coating film on the surface of roller,

which is applied to a substrate by moving the substrate

underneath the roller.

(24) "Sealer" is a coating, containing binders, which seals

the wood prior to application of the subsequent

coatings.

(25) "Semitransparent Stains" are coatings which are

formulated to change the color of a surface but not

conceal the surface.

(26) "Simulated Wood Materials" are materials, such as

plastic, glass, metal, that are made to give a wood-

like appearance or are processed like a wood product.

(27) "Stencil Coating" is an ink or a pigmented coating

which is rolled or brushed onto a template or stamp in

order to add identifying letters and/or numbers to wood

products.

(28) "Toner" is a wash coat which contains binders and dyes

or pigments to add tint to a coated surface.

(29) "Touch-up Coating" is a coating used to cover minor

coating imperfections appearing after the main coating

operation.

(30) "Transfer Efficiency" is the ratio of the weight of

coating solids deposited on an object to the total

weight of coating solids used in a coating application

step, expressed as a percentage.
