FIELD: chemistry.
SUBSTANCE: formulation composition contains: A) 5-95 wt % at least one radiation-curable resin, B) 5-25 wt % silicic acid, C) 0.1-10 wt % at least one adhesion promoter, D) 5-90 wt % at least one radiation-curable reactive diluent, E) 0.5-5 wt % at least one dispersant. The adhesion promoter is selected form phosphoric acid and/or phosphonic acid and/or products of reaction thereof with functionalised acrylates. The composition can additionally contain photoinitiators, pigments and additives, selected from diffusion promoting agents, delustering agents and degassing agents. The compositions are used as a primer, an intermediate layer, coating varnish and/or clear varnish, as well as for making coatings via a coil coating technique.
EFFECT: coatings have flexibility, thereby providing excellent protection of metal substrates from corrosion.
