FIELD: chemistry.
SUBSTANCE: described curable compositions comprise a polybenzoxazine component, a polyamine component, and a fluoropolymer component. The fluoropolymer component used is selected from fluoroolefin (co) polymers, perfluoroolefin (co) polymers, (co) polymers of perfluoroalkylvinylethers and (co) perfor alkoxyvinyl ether polymers.
EFFECT: invention provides protection against corrosion of substrates under the influence of high temperatures.
