METHOD OF APPLYING FLUOROPOLYMER COATINGS FOR PROTECTING SURFACES Russian patent published in 2010 - IPC C09D127/12 C23C28/00 C09D127/16 

FIELD: chemistry.

SUBSTANCE: invention relates to methods of applying fluoropolymer coatings for protecting production equipment and pipes, building structures, bridges and architectural materials which are used at average temperature of up to 120°C. The invention describes a method of applying fluoropolymer coatings for protecting surfaces which involves depositing onto a surface a layer of a solution in an organic solvent of fullerene C₆₀ or a mixture of fullerenes C₆₀ and C₇₀ with concentration of the latter between 0.01 and 0.5% per 1-10 mg of fullerenes per square metre of the surface. The surface is then dried naturally for not less than 2 hours, after which it is treated with fluoropolymer lacquer, which is a fluoropolymer solution in ester solvents or cyclic esters (50 g per litre) in amount of 100 ml of the solution per square metre of the surface. The surface is then dried in air under natural conditions for not less than 2 hours, after which it is finally dried with hot air at 90-100°C for 10-15 minutes.

EFFECT: invention increases efficiency of the protective surface based on fluoropolymers for long-term and efficient protection of articles, pipes, building structures and equipment and giving surfaces of different materials (natural and artificial stone, metal, wood, plastic) prolonged resistance to effects of aggressive agents of the environment and chemical agents.
