Summary:

Luna has developed an exceptionally durable, transparent fluid resistant coating utilizing a novel nanostructured formulation. There have been many recent research and commercial efforts in the area of water and oil repellent coatings that have demonstrated the ability to shed fluids quickly off of surfaces. Whereas many technologies and coatings have achieved the primary goal of achieving fluid shedding properties, they have all lacked mechanical and environmental durability, and/or have been difficult or expensive to apply. Luna Innovations has developed a class of transparent, abrasion resistant, fluid shedding coatings for multiple surfaces including glass, plastic, paint, and metals. The coating formulations can be easily applied in a single step by dip, flow, brush, or spray application. These hydrophobic/oleophobic coatings possess durable low energy surfaces leading to easy cleaning, corrosion resistance, and rain repellency. This technology utilizes a unique self-assembled nanostructured polymer-inorganic hybrid material leading to exceptional toughness for abrasion resistance and environmental stability. These coatings have numerous applications for automotive, aerospace, marine industrial, ophthalmic, and medical industries.
