Direct-to-Metal and Exterior Durable Siloxane Nonskid Coatings

     The use of siloxane-based coatings are becoming increasingly popular within the global coatings market due to their outstanding external durability, chemical resistance, cleanability, increased thermal stability, low toxicity and reduced VOC requirements.  These coatings are composed of both inorganic (silicone) and organic (carbon, hydrogen, nitrogen) materials, with each devoting unique characteristics to the coating.  Siloxane-based resins are more resistant to UV degradation (from sunlight) than the organic resins found in traditional coatings, thereby leading to enhanced external durability and hence a greater life-cycle for protective coatings.

     Researchers at the Naval Research Laboratory have recently designed a novel two-component (2K) siloxane-based non-skid coating for the flight decks and walkways of U.S. Navy ships.  The coating possesses greater external durability (color retention) than traditional epoxy-based non-skid coatings, does not absorb hydrocarbons and detergents, does not blush after application, provides exception traction for sailors, and can be roll or spray applied over a primed surface or directly to bare metal substrates.  The coating is currently being demonstrated on several Norfolk-based Navy ships.
