ANTICORROSION COATING COMPOSITION Russian patent published in 2010 - IPC C09D5/08 C09D5/10 

FIELD: chemistry.

SUBSTANCE: anticorrosion coating composition which can be used for protecting steel structures, objects and equipment from corrosion in atmospheric conditions and aqueous media, contains finely dispersed zinc powder, polystyrene and/or a copolymer of styrene with rubber, organic solvent and a rheological additive, and additionally a binder in form of a polyisocyanate prepolymer - aromatic polyisocyanate prepolymer based on diphenylmethanediisocyanate and moisture-absorbing additives. The finely dispersed zinc powder is obtained through physical vapour deposition. The moisture-absorbing additive used is tosylisocyanate and/or micronised highly porous crystalline aluminium silicat. The rheological additive used is bentonite or montmorillonite. The organic solvent used is a solvent of oil or xylene or butylacetate or methoxypropylacetate or white spirit or mixture thereof.

EFFECT: improved physical and mechanical and protective properties of the coating based on the composition, reduced presence of defects in the coating, reduced consumption of the composition, with preservation of protective properties, increased stability during storage and longer storage life.
