MIL-PRF-24667C

Abstract

This specification covers non-skid systems, coatings, and coverings for application to weather decks, flight decks, and hangar decks of air capable amphibious aviation and aviation ships. Coatings are applied to steel, aluminum, reinforced plastic, and special hull treatment (SHT) surfaces by spraying, rolling, or other application method as designated by the manufacturer of the non-skid system.<b><u>Intended Use:</u></b> The coatings covered by this specification are intended for use on general (walking) deck areas (Types I, II, III, IV, V, VI, VII, VIII, IX, X composition G, and XI), the flight and hangar decks of aircraft carriers (Types I, II, V, VI, VII, VIII, and IX compositions G and L) and on the landing decks of air-capable amphibious aviation and aviation ships (Types I, II, III, V, VI, VII, VIII, and IX composition G). Type I provides longer durability than Type II, however the factor of increased weight should be considered when using this system. Type V provides longer durability than Type I, but attention is given to the significantly shorter pot life. Type VI is a fast curing non-skid material for use when application windows are limited. Type VII is a temporary repair non-skid that is ready for service in 24 hours, however, it may have a relatively short service life making it unsuitable for normal non-skid installations. Type VIII is intended for application at low temperatures, but it should not be considered a fast cure product for application at normal or elevated conditions. Type III non-skid systems are intended for use where flexibility or thick smoothing capability is needed to correct drainage. Type III is not intended to be used on aircraft carriers if the underlayment is used due to compressibility of the materials under heavy aircraft. Type IV can be used on walking surfaces, but is not intended for aircraft landing decks. Type XI non-skid system is approved for use in well deck catwalk areas, airlocks, boatswain storerooms, elevator machinery rooms, boat gear repair station, chain locker sump, damage control maintenance shop, deck gear locker, drying rooms, machinery repair shops, mooring stations, nixie winch room, officer of the deck stations, replenishment-at-sea stations, rolling airframe missile handling equipment rooms, sideport door machinery spaces, signal shelter, stern gate machinery and operating gear rooms, and valve repair and test shops. Although laboratory testing is done between 35 &#176;F (2 &#176;C) and 90 &#176;F (32 &#176;C), each individual coating of these non-skid systems is applied in the fleet between 40 &#176;F (4 &#176;C) and 120 &#176;F (49 &#176;C).<br>
