Preparation of a New Material Based on Epoxy Oligomers for Forming Corrosion-Protective Coatings

New adhesive materials based on a single-part hot-cured epoxy adhesive for forming corrosion-protective coatings were obtained. Perfluoropentanoic acid N-methylpiperazide and polyethylenepolyamine were used as curing catalysts. The adhesive compounds in the cured state were characterized by the degr...

Description
Summary:New adhesive materials based on a single-part hot-cured epoxy adhesive for forming corrosion-protective coatings were obtained. Perfluoropentanoic acid N-methylpiperazide and polyethylenepolyamine were used as curing catalysts. The adhesive compounds in the cured state were characterized by the degree of swelling, gel fraction content, Vickers hardness, elastic modulus, and creep strain; their corrosion-protective properties with respect to low-carbon steel (St. 3) and aluminum–magnesium alloy (AMg-6) were determined. The chemical structure of the organic solvent and amine curing agent largely determines the operation characteristics of the coatings obtained.
