Durable Hydrophobic Coatings for Corrosion Protection of Metallic Materials

Keywords: , , , ,

Luna has developed an exceptionally durable, transparent, fluid resistant coating for corrosion mitigation on selected metals and alloys. There have been many recent research and commercial efforts in the area of superhydrophobic or water repellent coatings that have demonstrated the ability to shed fluids quickly off of surfaces. Whereas many surface treatments and coatings have achieved the primary goal of good fluid shedding properties, they have all lacked mechanical / environmental durability, or are difficult and expensive to apply. This new polymer-inorganic hybrid coating has a unique combination of fluid repellency and exceptional toughness for improved abrasion resistance and environmental stability. The coating formulation can be easily applied in a single step by dip, flow, brush, or spray with excellent adhesion to multiple surfaces including glass, plastic, paint, and a variety of metallic materials. The coating possesses low surface energy leading to easy cleaning, rain repellency, and excellent corrosion resistance. In addition to good fluid shedding properties, the coating has significantly higher density than traditional organic polymer coatings and is electrically insulating, resulting in improved barrier properties to water and corrosive ion permeation. The protective coating has numerous uses for automotive, aerospace, marine, and industrial applications.
