Coating means a material applied onto or impregnated into a substrate for protective, decorative, or functional purposes. Such materials include, but are not limited to, paints, varnishes, sealers, and stains.
Nuclear coating means a protective coating formulated and recommended to seal porous surfaces such as steel (or concrete) that otherwise would be subject to intrusions by radioactive materials. These coatings must be resistant to long-term (service life) cumulative radiation exposure [ASTM method D4082], relatively easy to decontaminate, and resistant to various chemicals to which the coatings are likely to be exposed [ASTM method D3912].
Clear coating means a transparent coating designed to provide the final gloss and resistance properties of the coating system;
Antenna coating means a coating labeled and formulated exclusively for application to equipment and associated structural appurtenances that are used to receive or transmit electromagnetic signals.
Touch-up coating means a coating used to cover minor coating imperfections appearing after the main coating operation.
Pretreatment coating means a coating which contains no more than 12% solids by weight, and at least 0.5% acid by weight, is used to provide surface etching, and is applied directly to metal surfaces to provide corrosion resistance, adhesion, and ease of stripping.
Metallic coating means a coating which contains more than five grams of metal particles per liter of coating, as applied. Metal particles are pieces of a pure elemental metal or a combination of elemental metals.
Repair coating means a coating used to re-coat portions of a previously coated product which has sustained mechanical damage to the coating following normal coating operations.
Dip coating means the application of a coating material to a substrate by dipping the part into a tank of the coating material.
Specialty coating means any coating that is manufactured and used for one (1) of the following specialized applications:
Topcoat means a coating that is applied over a primer on an aerospace vehicle or component for appearance, identification, camouflage, or protection. Topcoats that are defined as specialty coatings are not included under this definition.
Air dried coating means a coating that is dried by the use of air or forced warm air at temperatures up to 1940F (900C).
Fragrance means a substance or complex mixture of aroma chemicals, natural essential oils, and other functional components with a combined vapor pressure not in excess of 2 mm of Hg at 20oC, the sole purpose of which is to impart an odor or scent, or to counteract a malodor.
