Existing coating systems used for flight decks function as high friction surfaces that are corrosion and wear resistant. These coatings do not have radar absorbing properties to reduce radar cross-section of sea vehicles. Luna proposes to develop an economical, durable, corrosion resistant deck coating that has high friction and radar absorbing properties. Luna will utilize novel VOC-free resin chemistry, environmentally safe corrosion inhibitors and a combination of developmental nanomaterials and commercially available absorbers to achieve the desired combination of properties. The radar absorbing components of the coating will be based on a mixture of inorganic soft-magnetic particles and organic nanomaterials to achieve the desired coating permeability, permittivity, and graded properties to produce an effective broadband radar absorbing coating. The nanomaterials will allow for a lighter weight coating than can be produced with traditional radar absorbing materials while cost will be controlled by also using commercially available absorbers. The coating system will be formulated to be applied and repaired using conventional coating application processes and will have excellent durability, friction, wear resistance and corrosion performance to meet the existing Military requirements for non-skid coatings. The flight deck coating will be safe for workers to apply, VOC-free and use non-toxic corrosion inhibitors.
