Sept. 25, 2009 – Royal Adhesives and Sealants LLC has announced that its WS8031 Light Weight manganese dioxide cured polysulfide aircraft sealant is the first sealant to be fully qualified to SAE International’s aerospace material AMS3281D type 3 Class B aircraft fuel tank sealant specification.
WS 8031 aircraft sealant is manufactured at Royal Adhesives and Sealants Wilmington CA. facility, which is certified to the AS 9100, ISO 9001/2000 and AS7200/1 NADCAP quality systems requirements.
Ted Clark, Chief Executive Officer of Royal, commented: “WS8031 is a low density, sealant with a specific gravity of less than 1.05 or a 35% weight savings over traditional aerospace sealants. The weight savings we have achieved with WS 8031 are significant and will allow aircraft designers to meet important weight reduction targets without sacrificing sealant performance. As an example a fighter jet that uses between 25 to 30 gallons of sealant for fuel tank and pressure sealing in production would achieve a weight savings of between 100 to 150lbs”.
AMS3281D qualified aircraft sealants are used on the most advanced military aircraft and in addition to saving weight have outstanding resistance to aviation gasoline and jet fuel, as well as resistance to chemicals and petroleum products common to the aircraft industry and offers excellent flexibility and bond strength to most metal substrates like aluminum, stainless steel, steel, advanced composites and many coatings under extremes of temperature, weathering and stress.
Jeff Swindells, Product Manager Aerospace Sealants, also commented: “Royal continues to lead the market in the development of advanced light weight aircraft sealants and is the first company to be fully qualified to all three lightweight types called out in the AMS328D specification with WS 8030 qualified to Type 1 and WS 8032 qualified to Type 2 and now WS 8031 to Type 3”.
