PACKAGE STABILITY The ability of a paint or varnish to retain its original physical condition and not show excessive settling, viscosity loss, formation of grit or lose its drying properties after prolonged storage.
PAINT A mixture or dispersion of opaque pigments or powders in a liquid or vehicle. Now used in the general sense, which includes all organic and inorganic coatings such as enamels, varnishes, emulsions, bituminous coatings, etc. See also Emulsion, Latex, Oil, Water Paint .
PAINT CONTRACTOR An individual or firm whose primary business is providing surface preparation and coating application service.
PAINT DEFECT / FAILURE An inconsistency in appearance or a breach of the film’s integrity that diminishes the film’s function of protection and/or appearance. These defects/failures can be divided into at least three categories:
1) “Normal wear and tear” brought about by normal environmental and/or contact conditions over the duty cycle of the paint or coating system.
2) Appearance. Visual, cosmetic or aesthetic defects often brought about by improper application of previous systems or products.
3) Physical. These are coating integrity failures where the coating has ceased to provide protection to the substrate, thereby allowing it to suffer damage.
See MPI’s Identifiers.
PAINT FAILURE The loss of usefulness of the paint coating. The point at which the decorative and/or protective qualities of a coating have ended.
PAINT GAUGE Different instruments used for measuring the thickness of paint film in either wet or dry states. See Wet Film Thickness Gauge and Dry Film Thickness Gauge.
