FIELD: chemistry.
SUBSTANCE: invention relates to compositions of epoxy resin. Two-component epoxy resin composition for coating consists of resin component K1, containing at least one epoxy resin and at least one aldehyde, and hardener K2 component, containing at least one polyamine A1, containing at least one primary amine group, wherein ratio of aldehyde groups in component resin K1 to number of primary amino groups in hardener K2 component ranges from 0.1 to 1.1. Invention also discloses hardened composition, use of composition and aldehyde and method to reduce turbidity during hardening of epoxy resin composition.
EFFECT: technical result is composition exhibits good low turbidity effects and possesses good manageable viscosity and therefore is suitable, in particular, for area of application.
