ANTICORROSION COMPOSITION FOR COATING METAL Russian patent published in 2008 - IPC C09D127/18 C09D5/08 C08L27/18 

FIELD: chemistry.

SUBSTANCE: invention pertains to compositions based on soluble fluoropolymers, meant for protecting metallic surfaces from action of water and aggressive media. The compositions can be used in the chemical industry and other industries when making equipment. Description is given of the anticorrosive composition is given. It consists of a soluble copolymer of tetrafluoroethylene with vinylidene fluoride, organic solvents - acetone, ethylacetate, cyclohexanone and amyl acetate, low molecular epoxide diane resin of the "ЭД-8" or "ЭД-10" type, amine hardening agent product of condensation of formaldehyde and phenol with ethylenediamine of the "АФ-2" type, diluting agent - ethyl cellosolve and an extra filler - graphite or molybdenum sulphide with proposed ratios of the components. Description of the method of coating metals is also given, in which the above mentioned composition is deposited on a non-greasy surface. The first and subsequent layers are dried under the same conditions at temperature of 15-25°C for a period of 20-30 minutes, and final coating is done at 120-200°C for 4-6 hours.

EFFECT: protection of metal surfaces from water and aggressive media.
