Abstract
The present invention is directed to compositions derived from polymers containing metal-nitrogen bonds, which compositions exhibit, among other things, desirable oxidation resistance, corrosion resistance and hydrolytic stability when exposed to adverse environments, whether at ambient or at elevated temperatures, and which may be useful as, for example, protective coatings on surfaces.
Claims25
A method for forming a coating on at least one substrate material, comprising the steps of:
- A) combining in an amount sufficient to form a coating (1) at least one boron source material and (2) at least one solventless, liquid polymer comprising metal-nitrogen bonds to form a mixture;
- B) placing said mixture onto at least a portion of at least one substrate material;
- and
- C) heating said at least one substrate material having said mixture thereon to cause said mixture to react to form a coating on at least a portion of said at least one substrate.
A method for forming a coating on at least a portion of at least one substrate material, comprising the steps of:
- A) combining (1) at least one boron source material comprising an extended boron-boron bonding network, and (2) at least one metal-nitrogen polymer to form a mixture;
- B) heating at least a portion of said at least one substrate material;
- and
- C) placing said mixture onto at least a portion of said at least one heated substrate material in the presence of at least one oxidant to cause said coating to form.
A protective coating composition comprising:
- (A) at least one component comprising at least one boron source comprising an extended boron-boron bonding network;
- (B) at least one silicon-nitrogen polymer;
- (C) at least one filler material;
- and
- (D) at least one component comprising oxygen.
