| (G) Three-stage system--A topcoat system composed of
a pigmented basecoat portion, a semitransparent midcoat portion, and
a transparent clearcoat portion. The VOC content of a three-stage
system shall be calculated according to the following formula:
Attached Graphic
(H) Vehicle refinishing (body shops)--The coating of
motor vehicles, as defined in §114.620 of this title (relating
to Definitions), including, but not limited to, motorcycles, passenger
cars, vans, light-duty trucks, medium-duty trucks, heavy-duty trucks,
buses, and other vehicle body parts, bodies, and cabs by an operation
other than the original manufacturer. The coating of non-road vehicles
and non-road equipment, as these terms are defined in §114.3
and §114.6 of this title (relating to Low Emission Vehicle Fleet
Definitions; and Low Emission Fuel Definitions), and trailers is not
included.
(I) Wipe-down solutions--Any solution used for cleaning
and surface preparation.
(14) Vinyl coating--The use of printing or any decorative
or protective topcoat applied over vinyl sheets or vinyl-coated fabric.
(15) Wood parts and products. The following terms apply
to wood parts and products coating facilities subject to §115.421(14)
of this title.
(A) Clear coat--A coating which lacks opacity or which
is transparent and uses the undercoat as a reflectant base or undertone
color.
(B) Clear sealers--Liquids applied over stains, toners,
and other coatings to protect these coatings from marring during handling
and to limit absorption of succeeding coatings.
(C) Final repair coat--Liquids applied to correct imperfections
or damage to the topcoat.
(D) Opaque ground coats and enamels--Colored, opaque
liquids applied to wood or wood composition substrates which completely
hide the color of the substrate in a single coat.
(E) Semitransparent spray stains and toners--Colored
liquids applied to wood to change or enhance the surface without concealing
the surface, including but not limited to, toners and nongrain-raising
stains.
(F) Semitransparent wiping and glazing stains--Colored
liquids applied to wood that require multiple wiping steps to enhance
the grain character and to partially fill the porous surface of the
wood.
(G) Shellacs--Coatings formulated solely with the resinous
secretions of the lac beetle (laccifer lacca), thinned with alcohol,
and formulated to dry by evaporation without a chemical reaction.
(H) Topcoat--A coating which provides the final protective
and aesthetic properties to wood finishes.
(I) Varnishes--Clear wood finishes formulated with
various resins to dry by chemical reaction on exposure to air.
(J) Wash coat--A low-solids clear liquid applied over
semitransparent stains and toners to protect the color coats and to
set the fibers for subsequent sanding or to separate spray stains
from wiping stains to enhance color depth.
(K) Wood parts and products coating--The coating of
wood parts and products, excluding factory surface coating of flat
wood paneling.
(16) Wood furniture manufacturing facilities. The following
terms apply to wood furniture manufacturing facilities subject to §115.421(15)
of this title.
(A) Adhesive--Any chemical substance that is applied
for the purpose of bonding two surfaces together other than by mechanical
means. Adhesives are not considered to be coatings or finishing materials
for wood furniture manufacturing facilities subject to §115.421(15)
of this title.
(B) Basecoat--A coat of colored material, usually opaque,
that is applied before graining inks, glazing coats, or other opaque
finishing materials and is usually topcoated for protection.
(C) Cleaning operations--Operations in which organic
solvent is used to remove coating materials from equipment used in
wood furniture manufacturing operations.
(D) Continuous coater--A finishing system that continuously
applies finishing materials onto furniture parts moving along a conveyor
system. Finishing materials that are not transferred to the part are
recycled to the finishing material reservoir. Several types of application
methods can be used with a continuous coater, including spraying,
curtain coating, roll coating, dip coating, and flow coating.
(E) Conventional air spray--A spray coating method
in which the coating is atomized by mixing it with compressed air
at an air pressure greater than 10 pounds per square inch gauge (psig)
at the point of atomization. Airless and air-assisted airless spray
technologies are not conventional air spray because the coating is
not atomized by mixing it with compressed air. Electrostatic spray
technology is also not conventional air spray because an electrostatic
charge is employed to attract the coating to the workpiece. In addition,
high-volume low-pressure (HVLP) spray technology is not conventional
air spray because its pressure is less than 10 psig.
(F) Finishing application station--The part of a finishing
operation where the finishing material is applied (for example, a
spray booth).
(G) Finishing material--A coating used in the wood
furniture industry. For the wood furniture manufacturing industry,
such materials include, but are not limited to, basecoats, stains,
washcoats, sealers, and topcoats.
(H) Finishing operation--Those activities in which
a finishing material is applied to a substrate and is subsequently
air-dried, cured in an oven, or cured by radiation.
(I) Organic solvent--A liquid containing VOCs that
is used for dissolving or dispersing constituents in a coating; adjusting
the viscosity of a coating; cleaning; or washoff. When used in a coating,
the organic solvent evaporates during drying and does not become a
part of the dried film.
(J) Sealer--A finishing material used to seal the pores
of a wood substrate before additional coats of finishing material
are applied. Washcoats, which are used in some finishing systems to
optimize aesthetics, are not sealers.
(K) Stain--Any color coat having a solids content of
no more than 8.0% by weight that is applied in single or multiple
coats directly to the substrate. Includes, but is not limited to,
nongrain raising stains, equalizer stains, sap stains, body stains,
no-wipe stains, penetrating stains, and toners.
(L) Strippable booth coating--A coating that is applied
to a booth wall to provide a protective film to receive overspray
during finishing operations; is subsequently peeled off and disposed;
and reduces or eliminates the need to use organic solvents to clean
booth walls.
(M) Topcoat--The last film-building finishing material
applied in a finishing system. A material such as a wax, polish, nonoxidizing
oil, or similar substance that must be periodically reapplied to a
surface over its lifetime to maintain or restore the reapplied material's
intended effect is not considered to be a topcoat.
(N) Touch-up and repair--The application of finishing
materials to cover minor finishing imperfections.
(O) Washcoat--A transparent special purpose coating
having a solids content of 12% by weight or less. Washcoats are applied
over initial stains to protect and control color and to stiffen the
wood fibers in order to aid sanding.
(P) Washoff operations--Those operations in which organic
solvent is used to remove coating from a substrate.
(Q) Wood furniture--Any product made of wood, a wood
product such as rattan or wicker, or an engineered wood product such
as particleboard that is manufactured under any of the following standard
industrial classification codes: 2434 (wood kitchen cabinets), 2511
(wood household furniture, except upholstered), 2512 (wood household
furniture, upholstered), 2517 (wood television, radios, phonograph
and sewing machine cabinets), 2519 (household furniture not elsewhere
classified), 2521 (wood office furniture), 2531 (public building and
related furniture), 2541 (wood office and store fixtures, partitions,
shelving and lockers), 2599 (furniture and fixtures not elsewhere
classified), or 5712 (custom kitchen cabinets).
(R) Wood furniture component--Any part that is used
in the manufacture of wood furniture. Examples include, but are not
limited to, drawer sides, cabinet doors, seat cushions, and laminated
tops. However, foam seat cushions manufactured and fabricated at a
facility that does not engage in any other wood furniture or wood
furniture component manufacturing operation are excluded from this
definition.
(S) Wood furniture manufacturing operations--The finishing,
cleaning, and washoff operations associated with the production of
wood furniture or wood furniture components.
