Abstract
The present application provides corrosion protection compositions. In one embodiment, the corrosion protection composition of the present disclosure contains a polymer composition saturated with a clay that is intercalated with a C1-22 alkyl amine or a C1-22 alkyl ammonium cation. Methods of protecting metal surfaces from corrosion are also provided.
Claims19
A corrosion protection composition comprising a polymer composition that comprises about 3 wt. % phyllosilicate clay that is intercalated with a C1-22 alkyl amine or a C1-22 alkyl ammonium cation.
A corrosion protection composition comprising a diglycidyl ether of bisphenol A (DGEBA) resin composition saturated with a modified bentonite clay that is intercalated with a hexadecylamine or a hexadecylammonium cation, wherein an amount of the modified bentonite clay in the saturated resin composition is about 3 wt. %.
A method of protecting a metal surface from corrosion, the method comprising coating the metal surface with a corrosion protection composition comprising a polymer composition comprising about 3 wt. % of a clay that is intercalated with a C1-22 alkyl amine or a C1-22 alkyl ammonium cation.
A method of protecting a metal surface from corrosion, the method comprising coating the metal surface with a corrosion protection composition comprising an epoxy resin composition comprising 3 wt. % of a phyllosilicate clay that is intercalated with a C1-22 alkyl amine or a C1-22 alkyl ammonium cation, wherein a resistance of the coating on the metal surface is greater than about 5×10{circumflex over ( )}8 Ω·cm2.
