NR 422.02(19f)(a) (a) “Contact adhesive” means an adhesive that is all of the following:

NR 422.02(19f)(a)1. 1. Designed for application to bond 2 surfaces together.

NR 422.02(19f)(a)3. 3. Forms an immediate bond that is impossible, or difficult, to reposition after both adhesive-coated surfaces are placed in contact with each other.

NR 422.02(19f)(a)4. 4. Does not need sustained pressure or clamping of surfaces after the adhesive-coated surfaces have been brought together using sufficient momentary pressure to establish full contact between both surfaces.

NR 422.02(19f)(b) (b) “Contact adhesive” does not include any of the following:

NR 422.02(19f)(b)1. 1. Rubber cements that are primarily intended for use on paper substrates.

NR 422.02(19m) (19m) “Container” means the individual receptacle that holds a coating or coating component for storage and distribution.

NR 422.02(19s) (19s) “Conventional air spray” means a spray coating method in which the coating is atomized by mixing it with compressed air and applied at an air pressure greater than 10 psig at the point of atomization.

NR 422.02 Note Note: Airless and air assisted airless spray technologies are not conventional air spray because the coating is not atomized by mixing it with compressed air. Electrostatic spray technology is also not considered conventional air spray because an electrostatic charge is employed to attract the coating to the work piece.

NR 422.02(19v) (19v) “Cove base” means a flooring trim unit, generally made of vinyl or rubber, that has a concave radius on one edge and a convex radius on the opposite edge that is used in forming a junction between the bottom wall course and the floor or to form an inside corner.

NR 422.02(19x) (19x) “Cove base installation adhesive” means any adhesive intended by the manufacturer to be used for the installation of cove base or wall base on a wall or vertical surface at floor level.

NR 422.02(20) (20) “Cutback asphalt” means any asphalt which has been liquefied by blending with petroleum solvents (diluents) other than residual oils. Upon exposure to atmospheric conditions the diluents evaporate, leaving the asphalt to perform its function. Asphalt which contains less than 5% by weight petroleum solvents, disregarding any residual oils added, is not included in this definition.

NR 422.02(20m) (20m) “Cut-in clearcoat” or “jambing clearcoat” means a fast-drying, ready-to-spray clearcoat applied to surfaces such as door jambs and trunk and hood edges to allow for quick closure.
