FIELD: chemistry.
SUBSTANCE: present invention relates to radiation-curable compositions, as well as a coating containing said composition for protecting metal substrates from corrosion. The composition consists of radiation-curable urethane(meth)acrylate with OH number ≥ 10 mg KOH/g, a monofunctional, radiation-curable reactive diluent, an acidic adhesion promoter, a photoinitiator, a multifunctional reactive diluent, radiation-curable resins and other inert additives. The adhesion booster used is phosphoric or phosphonic acid or products of their conversion with functionalised acrylates.
EFFECT: radiation-curable compositions, having good corrosion-protective properties for metal substrates, which are elastic and capable of being well moulded.
