FIELD: chemistry.

SUBSTANCE: invention relates to crosslinked compositions for coatings. A crosslinked composition for coating is proposed, containing polyol, a poly-isocyanate linker, a catalyst for catalyzation of a reaction between -OH groups of the mentioned polyol and -NCO groups of the mentioned linker, tertiary acid described by the formula RR'R"CCOOH (I), where each R, R', and R" group is independently an alkyl or alkenyl group containing at least one carbon atom, provided that two or three of R, R', and R" groups may be bound to form a ring structure, and where R, R', and/or R" groups may be substituted, and, optionally, a complex-forming additive containing at least one -SH group. A kit and a binder module for the production of a crosslinked composition and a method for the production of coating are also proposed.

EFFECT: proposed composition has an improved ratio of viability/drying time, high early hardness, and long-term viability.
