Description
Class C09 encompasses colorants, protective coatings, surface treatments, and binding materials used across manufacturing and construction industries. It covers dyes for textiles and other substrates, paints and varnishes, polishes, natural and synthetic resins, adhesives, and sealants, along with their formulations and application methods. This residual class also captures chemical compositions and material applications that do not fit within more specialized chemical classifications, serving as a catch-all for coating and adhesive technologies not addressed elsewhere in the chemistry scheme.
