A.
Application equipment
				cleaning.
"Application equipment cleaning" means the process of flushing
				or removing resins and gel coats from the interior or exterior of equipment
				that is used to apply resin or gel coat in the manufacture of fiberglass
				parts.
B.
Assembly adhesives.
"Assembly adhesives" means any chemical substance that is applied for
				the purpose of bonding two surfaces together other than by mechanical
				means.
C.
Atomized
				application method.
"Atomized application method" means a resin
				application technology in which the resin leaves the application equipment and
				breaks into droplets or an aerosol as it travels from the application equipment
				to the surface of the part. Atomized application methods include, but are not
				limited to, resin spray guns and resin chopper spray guns.
D.
Boat.
"Boat" means any type
				of vessel, other than a seaplane, that can be used for transportation on the
				water.
E.
Clear gel
				coat.
"Clear gel coat" means gel coats that are clear or translucent so
				that underlying colors are visible. Clear gel coats are used to manufacture
				parts for sale. Clear gel coats do not include tooling gel coats used to build
				or repair molds.
F.
Closed
				molding.
"Closed molding" means any molding process in which pressure is
				used to distribute the resin through the reinforcing fabric placed between two
				mold surfaces to either saturate the fabric or fill the mold cavity. The
				pressure may be clamping pressure, fluid pressure, atmospheric pressure, or
				vacuum pressure used either alone or in combination. The mold surfaces may be
				rigid or flexible. Closed molding includes, but is not limited to, compression
				molding with sheet molding compound, infusion molding, resin injection molding
				(RIM), vacuum-assisted resin transfer molding (VARTM), resin transfer molding
				(RTM), and vacuum-assisted compression molding. Processes in which a closed
				mold is used only to compact saturated fabric or remove air or excess resin
				from the fabric (such as in vacuum bagging), are not considered closed molding.
				Open molding steps, such as application of a gel coat or skin coat layer by
				conventional open molding prior to a closed molding process, are not closed
				molding.
G.
Cured
				resin.
"Cured resin" or "cured gel coat" means resin or gel coat that
				has changed irreversibly from a liquid to a solid.
H.
Fiberglass boat.
"Fiberglass
				boat" means a vessel in which either the hull or deck is built from a composite
				material consisting of a thermosetting resin matrix reinforced with fibers of
				glass, carbon, aramid, or other material.
I.
Filled resin.
"Filled resin"
				or "filled production resin" means a resin to which an inert material has been
				added to change viscosity, density, shrinkage, or other physical
				properties.
J.
Flowcoater
. "Flowcoater" means a nonatomizing application method
				of applying resins and gel coats to an open mold with a fluid nozzle in a fan
				pattern with no air supplied to the nozzle.
K.
Gel coat.
"Gel coat" means a
				polyester resin surface coating, either pigmented or clear, that provides a
				cosmetic enhancement and improves resistance to degradation from exposure to
				the elements.
L.
Mixing.
"Mixing" means any operation in which resin or gel coat,
				including the mixing of putties or polyester resin putties, is combined with
				additives that include, but are not limited to, fillers, promoters, or
				catalysts.
M.
Mold.
"Mold" means the cavity or surface into or on which gel coat, resin, and fibers
				are placed and from which finished fiberglass parts take their form.
N.
Monomer VOC.
"Monomer VOC"
				means a relatively low-molecular-weight organic compound such as styrene that
				combines with itself, or other similar compounds, by a cross-linking reaction
				to become a cured thermosetting resin.
O.
Monomer VOC content .
"Monomer VOC content " means the weight of the monomer, divided by the weight
				of the polymer.
P.
Nonatomized application method.
"Nonatomized application method"
				means any application technology in which the resin is not broken into droplets
				or an aerosol as it travels from the application equipment to the surface of
				the part. Nonatomized application methods include, but are not limited to,
				flowcoaters, chopper flowcoaters, pressure-fed resin rollers, resin
				impregnators, and hand application (for example, paint brush or paint
				roller).
Q.
Open molding
				resin and gel coat operation
. "Open molding resin and gel coat
				operation" means any process in which the reinforcing fibers and resin are
				placed in the mold and are open to the surrounding air while the reinforcing
				fibers are saturated with resin. For the purposes of this Chapter, open molding
				includes operations in which a vacuum bag or similar cover is used to compress
				an uncured laminate to remove air bubbles or excess resin, or to achieve a bond
				between a core material and a laminate.
R.
Pigmented gel coat.
"Pigmented gel coat" means opaque gel coats used to manufacture parts for sale.
				Pigmented gel coats do not include tooling gel coats used to build or repair
				molds.
S.
Polyester resin
				materials.
"Polyester resin materials" means unsaturated polyester
				resins, such as isophthalic, orthophthalic, halogenated, bisphenol A, vinyl
				ester, or furan resins; cross-linking agents; catalysts; gel coats; inhibitors;
				accelerators; promoters; and any other material containing VOC used in
				polyester resin operations.
T.
Polyester resin operations.
"Polyester resin operations" means
				fabricate, rework, repair, or touchup products for commercial, military, or
				industrial use by mixing, pouring, hand laying-up, impregnating, injecting,
				forming, winding, spraying, and/or curing by using unsaturated polyester resin
				materials.
U.
Production
				resin.
"Production resin" means any resin used to manufacture parts for
				sale. Production resins do not include tooling resins used to build or repair
				molds, or assembly adhesives as defined in this Chapter.

				portion of the fabrication process that requires the addition of polyester
				resin materials to portions of a previously fabricated product in order to mend
				damage.
W.
Resin.
"Resin" means any thermosetting resin with or without pigment containing
				styrene (CAS No. 100-42-5) or methyl methacrylate (CAS No. 80-62-6) and used to
				encapsulate and bind together reinforcement fibers in the construction of
				fiberglass parts.
X.
Resin
				impregnator.
"Resin impregnator" means a mechanical nonatomizing
				composite materials application method in which fiber reinforcement is
				saturated with resins in a controlled ratio for each specific composite
				product.
Y.
Roll-out.
"Roll-out" means the process of using rollers, squeegees, or similar tools to
				compact reinforcing materials saturated with resin to remove trapped air or
				excess resin.
Z.
Skin
				coat
. "Skin coat" means a layer of resin and fibers applied over the gel
				coat to protect the gel coat from being deformed by the next laminate
				layers.
AA.
Tooling gel
				coat.
"Tooling gel coat" means the gel coat used to build or repair
				molds (also known as tools) or prototypes (also known as plugs) from which
				molds will be made.
BB.
Tooling resin.
"Tooling resin" means the resin used to build or
				repair molds (also known as tools) or prototypes (also known as plugs) from
				which molds will be made.

				necessary to cover minor imperfections.
DD.
Vacuum bagging.
"Vacuum
				bagging" means any molding technique in which the reinforcing fabric is
				saturated with resin and then covered with a flexible sheet that is sealed to
				the edge of the mold and where a vacuum is applied under the sheet to compress
				the laminate, remove excess resin, or remove trapped air from the laminate
				during curing. Vacuum bagging does not include processes that meet the
				definition of closed molding.
EE.
Vinylester resin.
"Vinylester resin" means a thermosetting resin
				containing esters of acrylic or methacrylic acids and having double-bond and
				ester linkage sites only at the ends of the resin molecules.
