Corrosion Resistance of Epoxy Coatings Modified by Bis-Silane Prepolymer on Aluminum Alloy
نویسندگان
چکیده
In this communication, a bis-silane prepolymer was used to modify epoxy resin, aiming enhance the corrosion resistance of coatings on aluminum alloy substrates. The prepared by tetraethoxysilane (TEOS) and γ-glycidoxypropyl trimethoxysilane (GPTMS). behavior silane-epoxy studied. Compared with silane monomer-modified coatings, bis-silane-modified have lower coating capacitance (Cc), higher charge transfer resistances (Rdl), double layer (Cdl) during long-time immersion. It indicates that has stronger waterproof permeability substrate protection ability. addition, due leaching component cross-linking reaction between different silanes immersion process, exhibit much “self-healing”
