S
SAG:
SEALER:
- Material
applied before topcoat to increase color holdout and uniformity
of color and adhesion.
SECONDARY
COLORS:
- Mixture of
two primary colors
to produce a second color. Example: red and yellow make orange.
SEEDY:
- Rough or
gritty appearance of paint due to very small insoluble particles.
SETTLING:
SHADE:
- A variation
of color. Example 1: a green shade blue. Example 2: light blue
versus dark blue.
SHRINKAGE:
- Tightening
or shrinking of paint film as solvent evaporates.
SIDETONE
"FLOP":
- The color
of a finish when viewed from a side angle.
SINGLE STAGE:
- A one-step
paint procedure of applying color, protection and durability in
one application. No clear is used.
SIPHON FEED
GUN:
- Any paint
gun which uses air flowing over an opening to create a vacuum
to draw paint up a tube to be atomized.
SOLIDS:
- The part
of the paint, pigments and resin which do not evaporate.
SOLID COLOR:
- Colors that
contain no metallic flakes in the pigment portion of paint. These
colors have opaque pigmentation or properties in the paint film.
SOLUTION:
- A homogeneous
mixture of two or more dissimilar substances.
SOLVENT CLEANER:
- Solvent-based
cleaning material used to remove contamination from surfaces prior
to refinishing.
SOLVENT POP:
- Blisters
in the surface of a film caused by trapment of solvent.
SPLITTING:
- The breaking
open of an undercoat or topcoat into long cracks resembling the
look of a "dry river bottom".
SPOT REPAIR:
- The process
of repairing only a portion of a panel or vehicle.
SPRAY
PATTERN:
- Spray from
the paint gun adjusted from a very small, almost round pattern
to a wide, flat, somewhat oval shape.
STABILIZER:
- Special resin-containing
solvent used in basecoat color to lower viscosity helping in metallic
control and recoat times.
STRENGTH
OF COLOR:
- The hiding
ability of a pigmented toner or colorant.
SURFACER:
T
TACK COAT:
- Usually the
first light coat of paint is allowed to set and become sticky
before additional coats are applied.
TACK FREE:
- Time in the
drying of a paint film where it is not sticky but not completely
cured.
TACK RAGS:
- A sticky
cheese cloth used to remove dust before painting.
TEXTURE:
- The amount
of orange peel or roughness in a dried paint film.
THERMOSPLASTIC
PAINT:
- Material
which with the addition of heat becomes soft and pliable, returning
to solid when cooled, i.e., lacquer.
THERMOSETTING
PAINT:
- Type of paint
that becomes hard when heated and thereafter is cured, i.e., enamels,
urethanes.
THINNER:
- Solvent material
used to reduce the viscosity of lacquers.
THREE-STAGE
SYSTEM:
- A three-step
paint procedure. First a highly pigmented color coat is applied
to achieve hiding, referred to as the groundcoat. This groundcoat
is then followed by the intermediate coat. The intermediate coat
is applied using a transparent mica in a number of single coats
until the desired effect is obtained. This finish requires a clearcoat
for gloss protection and durability, which is applied last.
TINT:
- A pure toner
used for the changing of another color.
TINTING:
- The act of
changing one color by adding another.
TITANIUM
DIOXIDE:
- A commonly
used white pigment with high hiding power.
TONERS:
- Made with
ground pigments, solvent and resin. Used in the intermix system
to produce colors.
TOP-COAT:
- The pigmented
color portion of the painting process.
TOUGHNESS:
- The ability
of a finish to withstand abrasion, scratches, etc.
TRANSFER-EFFICIENCY:
- The ratio
in a percentage of the amount of paint actually applied to a surface
compared to the amount of material used.
TWO-COMPONENT:
- A paint material
which must have a catalyst or hardener to react.
U
ULTRA VIOLET
LIGHT:
- The part
of the electromagnetic spectrum which can cause fading of paint.
Located just beyond the visible part of spectrum.
UNDERCOAT:
- The coatings
below the top color coat that help in adhesion and corrosion resistance.
V
VISCOSITY:
- Determined
by allowing a measured amount to flow through an orifice and measuring
the time it takes for this amount to flow.
V.O.C. (VOLATILE
ORGANIC COMPOUND):
- Any organic
compound that evaporates and subsequently participates in atmospheric
photo-chemical reaction; that is, any organic compound other than
those that the administrator designates as having negligible photochemical
activity.
W
WATERBORNE
COATING:
- A coating
containing more than five percent water in its volatile fraction.
