H
HANDSLICK:
- The time
it takes for a wet paint film to become ready for another coat
of paint.
HARDENER:
- A material
used to speed cure of an enamel.See also CATALYST.
HARDNESS:
- Resistance
of a paint film to surface damage measured in pencil hardness.
HIGH BAKE:
- The baking
of paint above 180° F.
HIGH SOLID:
- Paints and
undercoats which have more pigment and resin (film formers) than
their regular equivalent.
HIGH STRENGTH/HIGH
CONCENTRATED:
- The amount
of pigment in the volume solid portion is in a higher amount,
more pigment vs. resin.
HIGH VOLUME
LOW PRESSURE (HVLP):
- Spray
equipment which delivers material at a low pressure of no
more than 10 PSI (at the air cap), however, with greater volume
of air.
HIT:
- Small increment.
A gradual increase in quantity. Term used in color adjustment.
HOLD-OUT
(COLOR):
- The ability
of an under-coat to stop or greatly reduce the topcoat from soaking
into it.
HUMIDITY:
- The amount
or degree of water vapor in the air measured in percent.
I
INCANDESCENT
LIGHT:
- Light emitted
from a burning filament in a glass bulb.
INCREMENT:
- A gradual
increase in quantity.
INFRA-RED
LIGHT:
- Portion of
electromagnetic spectrum just below the visible light range. Can
be used to cure paint due to heat being produced.
INNERCOAT
ADHESION:
- The ability
of one coat of paint to stick to another coat.
INTERMIX:
- The mixing
of specific colors by adding different components or colorants
to produce a usable mixture at the paint store or shop level.
ISOCYANTE/POLYISOCYANATE:
- Material
containing a functional group of nitrogen, carbon and oxygen,
used in urethane catalyst and hardener to cross link material
into a solid urethane film
J
JELLED:
- Thickening
of paint to an unusable form due to drying or curing, before being
used.
L
LACQUER:
- A paint which
dries by solvent evaporation which can be redissolved in its own
solvent.
LET DOWN:
- The process
of reducing the intensity of a colorant or mass tone through the
addition of white or silver, allowing you to see cast and strength.
LIFTING:
- The soaking
of a solvent into a soluble undercoat causing swelling, then causing
the topcoat to wrinkle from underneath.
LOW-BAKE:
- Baking of
a paint film up to 180¡ F.
LOW PRESSURE
COAT:
- The process
of applying the final coat of paint at a lower air pressure. Used
to uniform a finish or blending.
M
MASKING:
- Process of
applying pressure, sensitive tape and paper to a vehicle to prevent
paint from being applied where it is not wanted.
MASSTONE:
- The color
of an undiluted colorant.
M.E.K. (METHYL
ETHYL KETONE):
- Solvent used
in many paint reducers and thinners.
METALLIC
COLOR:
- Colors containing
various sizes of aluminum flakes. These flakes have reflective
properties and when used in combinations and/or amounts, modify
the optical characteristics of the color.
METAMERISM:
- A phenomenon
exhibited by two colors that match under one or more light sources,
but do not match under all light sources or viewing conditions.
MICA COLOR:
- Colors containing
various sizes and/or colors of mica. Mica flakes have several
optical characteristics allowing light to reflect, pass through
and absorb. When added to color alone or with metallic flake,
cause the color to look different depending on the angle of view.
MIL:
- A measure
of paint film thickness equal to one/one-thousandth of an inch.
"MINI BELL":
- Equipment
used to apply paint electrostatically consisting of a spinning
disk to which paint is applied. The spinning disc is charged electrically
and paint is atomized through centrifugal force.
MIST COAT:
- A thin sprayed
coat to uniform metallic finishes. Also used to blend colors.
Sometimes used with light amounts of solvents to uniform finish
and/or increase gloss.
MOTTLING:
- Blotches
of metallic or mica particles in a paint film.
M.S.D.S.
(MATERIAL SAFETY DATA SHEETS):
- Used in locating
information on all paint materials.
