Basecoat means a coat of colored material, usually opaque, that is applied before graining inks, glazing coats, or other opaque finishing materials and is usually topcoated for protection.
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.
Oxides of nitrogen means the sum of the volume mixing ratio (ppbv) of nitrogen monoxide (nitric oxide) and nitrogen dioxide expressed in units of mass concentration of nitrogen dioxide (µg/m3);
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.
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.
Roll coating means the application of a coating material to a substrate by means of hard rubber or steel rolls.
Floor coating means an opaque coating that is labeled and designed for application to flooring, including but not limited to, decks, porches, steps, and other horizontal surfaces which may be subject to foot traffic.

Automotive windshield washer fluid does not include fluids placed by the manufacturer in a new vehicle.
Architectural coating means a coating applied to stationary structures and their appurtenances, to mobile homes, to pavements, or to curbs.
Low-solids coating means a coating containing 0.12 kilogram or less of solids per liter (one pound or less of solids per gallon) of coating material.
Diatomaceous earth filtration means a process resulting in substantial particulate removal in which a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and while the water is filtered by passing through the cake on the septum, additional filter media known as body feed is continuously added to the feed water to maintain the permeability of the filter cake.
