Conformal Coating Composition for Preventing Sulfur-Related Corrosion

Strategic Insights -

United States Patent and Trademark Office has received an application for a US Patent with the title "CONFORMAL COATING COMPOSITION CONTAINING METAL NANOPARTICLES TO PREVENT SULFUR RELATED CORROSION". The patent application, published on July 16, 2015, was filed by International Business Machines Corporation. The inventors, Dylan J. Boday, Joseph Kuczynski, Jason T. Wertz, and Jing Zhang, have developed a conformal coating composition that protects metal surfaces from sulfur-related corrosion.

Key Takeaways:

  • The conformal coating composition contains a polymer and metal nanoparticles blended together to prevent corrosion.
  • The composition includes an apparatus with an electronic component, metal conductors, and a polymer conformal coating containing metal nanoparticles.
  • The metal nanoparticles in the conformal coating react with sulfur components in the air to prevent corrosion.
  • The invention is designed to protect metal conductors from corrosion caused by elemental sulfur, hydrogen sulfide, and sulfur oxides.
  • The conformal coating composition is applicable to various industries, including but not limited to, aerospace, automotive, and electronics.
  • The inventors' approach utilizes the corrosion-reducing properties of metal nanoparticles to provide a protective layer on metal surfaces.
  • The invention targets the prevention of sulfur-related corrosion, which can cause significant damage to metal components.
