PROTECTIVE COATING COMPOSITION Russian patent published in 2013 - IPC C09D163/02 C09D183/14 

FIELD: chemistry.

SUBSTANCE: invention relates to polymer compositions based on modified epoxide oligomers, and specifically to protective coating compositions of composite materials and is recommended for protecting the inner surface of aircraft integral fuel tanks made from polymer composite materials, particularly carbon fibre-reinforced plastic. The protective coating composition of composite materials contains epoxy-diane resin, a modifier - polysulphide rubber, a curing agent - organosilicon amine, a pigment, mineral filler, a reactive diluent - monoglycidyl ether of alkylphenol and an organic solvent. The filler is natural or synthetic magnesium, aluminium or calcium silicates.

EFFECT: obtaining a composition having high fuel- and water-resistance, improved adhesion and physical-mechanical properties during prolonged use in liquid aggressive media.
