FIELD: coatings.
SUBSTANCE: invention relates to a liquid composition of a thermosetting polymer coating based on organic solvents for painting by the coil coating method. The liquid composition includes at least a linear or branched polyester resin, a crosslinking agent, a viscosity regulator, and a catalyst. Hydroxyfunctional resin is taken as a polyester resin, and chitosan is taken as a crosslinking agent in an amount of up to 5% of the mass of the finished liquid composition of the coating.
EFFECT: technical result is an improvement in the weather resistance and hardness of the produced polymer coating with the maintained or improved bending and extensibility thereof.
