DEFINITION

Classification: 510/201

For removing integral organic coating, sealant, or finish from a substrate (e.g., stripping paint, varnish, etc.):

(under subclass 109) Compositions specialized for accomplishing or facilitating the removal of an organic protective or ornamental coating, sealant, or finish from a substrate to which it is integrally attached.

(1) Note. Many of these compositions function by loosening the coating, thus facilitating its removal by peeling, rinsing, etc.
