WEATHERPROOF COMPOSITE OF EXTERIOR FILM Russian patent published in 2017 - IPC C08J7/04 C09D175/14 C03C17/32 B32B27/40 C08G18/62 C08G18/72 

FIELD: chemistry.

SUBSTANCE: invention relates to film composites with one coating of solid coating material. The film composite consists of a substrate containing at least one layer of polyester film, wherein on one side the substrate has a weatherproof solid coating consisting of: at least one monomer or oligomer of a multifunctional acrylate, dual-cure resin containing an aliphatic urethane polyacrylate having isocyanate functional groups and aliphatic urethane polyacrylate having hydroxyl functional groups, ultraviolet (UV) stabilizer and photoinitiator. In this case dual-cure solid coating has adhesion to the outer surface of the polyester film layer of the substrate without need for the second solid coating layer or primer layer. The composition of solid single-layer coating is also described.

EFFECT: purpose of the invention is providing film composites with one coat of solid coating material, which have significantly improved adhesion, improved weather resistance and high resistance to abrasion and cracking.
