- Lacquer paint
whose resin is formed with cellulose, a natural resin made from
which do not react with sunlight to cause ozone or smog.
- A finish
that is not transparent. Light cannot be seen through it and does
not allow what is underneath to show through.
- Texture in
a paint film that resembles the peel of an orange. Caused by improper
reduction or application.
(OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION):
- A federal
agency which sets safety and health regulations for most of the
U.S. industries and businesses.
- Placing one
coat of paint alongside another, one partly extending over the
- Paint which
during application will stick to adjacent panels not being painted.
reaction between oxygen and another substance, causing paint film
curing, paint film failure or metal rusting.
- A triatomic
very reactive form of oxygen that is a bluish, irritating gas
of pungent odor. Formed naturally in the atmosphere by a photochemical
reaction and is a major air pollutant in the lower atmosphere
but a beneficial component of the upper atmosphere.
- The dropping
or settling of the solids in a reduced or unreduced paint to the
bottom of paint gun or can.
- Painter can
control range of reduction, air pressure, speed of travel, flash
of a complete panel.
- Loss of adhesion
between one coat of paint to succeeding coats or coatings.
- Organic solvents
that react with ultra violet light to form oxidants such as ozone
- An insoluble
finely ground powder, either natural, synthetic, inorganic or
organic. It provides color, hardness, durability, hiding and corrosion
resistance to paint.
- Paint imperfection
resembling a hole about the size of the head of a straight pin.
Caused by solvent entrapment or air bubbles.
- The amount

air pressure into it. This then forces the paint to the gun for
- Red, yellow
and blue. These colors resemble no other color and cannot be formed
by mixtures of any other colors.
- The coating
applied to a properly prepared substrate to give corrosion resistance,
adhesion and chemical resistance.
- An undercoat
used to improve adhesion and color holdout with minimum filling
used to fill imperfections, with primer qualities and maximum
filling properties. Must be sanded.
- Small wrinkles
or buckles caused by a non-compatibility of additives.
used to fill imperfections in a substrate. Composed of a lacquer
or polyester resin. Applied with a squeegee and sanded smooth.
- The dispersion
of metallic or mica flakes with no specific pattern.
- A solvent
used to lower the viscosity of an enamel or urethane.
- The act of
replacing or repairing a painted surface, usually undercoat and
- Adding heat
to such a degree as to cause the paint to melt and become a liquid.
- A clear or
semi-clear part of a paint film which gives solids or film build.
Resin gives the finish shine, gloss, durability, adhesion, handling
and drying characteristics.
- Slowest evaporating
amount of coating failing to adhere uniformly over the surface,
thus flowing unevenly in a small area.
