Alpha List for Definitions
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

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.
