Present invention relates to an aqueous primer composition. The aqueous primer composition contains: a. at least one composition of a heat-curable self-emulsifying epoxy resin obtained by reacting (a) epoxy resin, (b) a polyatomic phenol and (c) an amine-epoxide adduct, where the amine-epoxide adduct is a product of reaction of an aromatic polyepoxide with polyoxyalkylene amine; b. at least one composition of a heat-curable non-self-emulsifying resin having an epoxide base which has epoxide functionality from 1.8 to 4 and epoxide equivalent weight from 100 to 200; c. water; and d. at least one curing agent. The invention also describes a method of producing the aqueous primer composition.

Anticorrosion protection of metal structures and large-size industrial equipment

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.

Protective coating composition based on chlorosulphonated polyethylene

Protective coating composition based on chlorosulphonated polyethylene

Invention relates to protective coating compositions based on chlorosulphonated polyethylene for protecting metal and concrete from external action. The protective coating composition based on chlorosulphonated polyethylene contains pigments, organic solvents, polymeric petroleum resin as a modifying additive and curing agent and zinc phosphate.

Corrosion-protective system for metals and anticorrosion pigment therefor

Corrosion-protective system for metals and anticorrosion pigment therefor

Invention relates to protecting a metal base from corrosion by applying a corrosion-protective system thereon. The system contains at least one coating applied onto the base which consists of an organic matrix in which anticorrosion pigments are dispersed. The pigments are formed by an alloy of at least two metals and inevitable impurities. The organic matrix is a primer for a multilayer paint coat and/or an anticorrosion primer for a multilayer paint coat and/or coloured lacquer for a multilayer paint coat and/or finish lacquer for multilayer paint coat and/or lacquer for coating metal and/or an adhesive for gluing metal sheets and/or oil and/or wax and/or an oil-wax emulsion.

Method of making gradient coatings - rust modifiers

Invention relates to the paint industry, particularly compositions and methods of producing water-resistant anticorrosion primers for protecting corroded surfaces of different metals and alloys before subsequent application of paint coatings or as independent protective coating. The method of making gradient coatings involves mixing components which comprise epoxy resin, a pigment, glycidyl ether of phosphoric acid and a curing agent, and applying onto the surface. The epoxy resin is first mixed with the pigment, followed by addition of the glycidyl ether of phosphoric acid in which in which a complexing agent - disodium salt of 3,5-pyrocatechin-disulphonic acid (tiron) is dissolved and the curing agent. The mixture is held until a given degree of demixing is achieved and then cured. The glycidyl ether of phosphoric acid used is either triglycidyl phosphate or diglycidyl phosphate or diglycidyl methylphosphonate.
