FIELD: chemistry.
SUBSTANCE: claimed invention relates to field of polyurethane compositions, as well as to their application, in particular, as two-component binding material, sealant, sealing mass, coating or floor coating. Described is composition, used as glue, sealant, sealing mass, coating or floor coating, paint, varnish or priming coat, containing: a) at least one aldimine A of formula 
and b) at least one polyisocyanate P. Described is two-component composition, used as glue, sealant, sealing mass or coating, consisting of: component K1, which contains: a) at least one aldimine A of formula (I) and b) at least one substance RS, which contains at least two groups, reactionable with respect to isocyanate groups, and/or water, and component K2, which contains c) at least one polyisocyanate P. Described is product of AV binding, obtained in the course of reaction of aldimine A of formula (I) with polyisocyanate P, contained in said compositions, and aldimine of formula 
. Also described are: method of gluing substrate S1 with substrate S2, which includes the following stages: i) application of described composition on substrate S1; ii) contact of applied composition with substrate S2, continuing for the time of composition viability; or i′) application of composition on substrate S1 and on substrate S2; ii′) contact of substrates with applied composition with each other for the time of composition viability; with substrate S2 consisting of material the same or different from substrate 1; application of said composition as glue, sealant, sealing mass, coating, floor coating, paint, varnish or priming coat and hardened composition, used as glue, sealant, sealing mass, coating, floor coating, paint, varnish or priming coat, obtained from said composition and moisture.
EFFECT: compositions possess long viability, with fast gain of strength and demonstration of high indices of strength and elasticity modulus in hardened state.
