ANTICORROSION PROTECTION OF METAL STRUCTURES AND LARGE-SIZE INDUSTRIAL EQUIPMENT Russian patent published in 2013 - IPC C09D5/08 C08L63/00 B32B1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to methods of anti-corrosion protection of metal structures and large-size industrial equipment operating in atmospheric conditions by depositing a paint coat onto the surface of the equipment. Disclosed is an anti-corrosion protection method which involves depositing a prime coat onto the metal surface, followed by tack-free drying, and then depositing a top coat followed by drying until complete setting. The prime coat and the top coat are made from a composition which contains (wt %): silicone epoxy resin (32.0-52.0), nanodispersed fluoroplastic (2.0-4.0), aminosilane curing agent (8.0-12.8), target additives (1.84-2.32), pigments and filler materials (3.4-21.6), organic solvents - the balance.

EFFECT: anti-corrosion protection of metal structures and large-size industrial equipment for more than 15 years in atmospheric conditions of moderate and cold climates while increasing cost effectiveness of painting by using the same paint material as a prime coat and a top coat, fewer layers and reduced total thickness of the paint coat.
