Introduced: September 1968

Description

C09D encompasses coating compositions and related products used to impart color, protection, or functional properties to surfaces. This subclass covers paints, varnishes, lacquers, inks, wood stains, filling pastes, and chemical removers for paints or inks, as well as solid or paste colorants for printing and decorative applications. The classification includes formulations based on various binders (such as resins, oils, or polymers) and their application methods, but excludes adhesives and natural resins classified elsewhere in C09. Inventions in this subclass typically address composition design, performance characteristics, environmental properties, or manufacturing processes for coating systems.

Glossary

aliphatic radical aliphatic radicals an acyclic or a non-aromatic carbocyclic carbon skeleton which is considered to be terminated by every bond to: an element other than carbon; a carbon atom having a double bond to one atom other than carbon; an aromatic carbocyclic ring or a heterocyclic ring. use of materials for coating compositions the use of known or new polymers or products. rubber rubbers includes: natural or conjugated diene rubbers; or rubber in general (for a specific rubber, other than a natural rubber or a conjugated diene rubber, see the group provided for coating compositions based on such macromolecular compounds. filling pastes materials used to fill up the holes or cavities of a substrate in order to smooth its surface prior to coating.
