CHEMICAL COMPOSITION OF HALOGENATED POLYIMIDE SILOXANE AND GLASS ARTICLES WITH COATINGS WITH LOW FRICTION COEFFICIENT FROM HALOGENATED POLYIMIDE SILOXANE Russian patent published in 2020 - IPC C03C17/30

Abstract RU 2726719 C1

FIELD: chemistry; glass industry.

SUBSTANCE: present invention relates to coatings with low friction coefficient applied on glass containers, such as drug package. In particular, disclosed is a coated glass article comprising: a glass container comprising a first surface and a second surface opposite the first surface, and coating with low friction coefficient associated with at least part of first surface of glass container. Coating with low friction coefficient includes a polyimide chemical composition. Polyimide chemical composition is halogenated and includes a siloxane moiety. Polyimide chemical composition is also a copolymer formed from at least a monomer containing a halogenated anhydride.

EFFECT: technical result is higher resistance to mechanical damage.
