Formulated to the Def Stan 80-211 (formerly DTD 369B) standard, this barium chromate-inhibited paste provides an active chemical defense against corrosion. It is specifically designed for \"wet-assembly,\" where the compound is applied to fasteners and faying surfaces during installation to displace air and moisture, creating a high-integrity seal that prevents galvanic and crevice corrosion in the most demanding flight environments.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003cbr\u003eActive Chemical Protection: The barium chromate content provides superior corrosion inhibition, chemically neutralizing electrolytes that penetrate structural joints.\u003cbr\u003eNon-Hardening Formula: Remains permanently tacky and elastic, ensuring the seal does not become brittle or crack due to airframe vibration, structural flexing, or thermal cycling.\u003cbr\u003eDissimilar Metal Barrier: Acts as an electrical insulator between mismatched alloys (e.g., steel or titanium fasteners in aluminum structures), effectively halting galvanic decay.\u003cbr\u003eEnvironmental Resilience: Offers excellent resistance to water washout, aviation fuels, and hydraulic oils, maintaining its protective properties throughout long service intervals.\u003cbr\u003eStandardized Procurement: Fully codified under NSN 8030-99-220-2495, ensuring compliance with military and commercial NATO-standard maintenance protocols.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApplications\u003c\/strong\u003e\u003cbr\u003eFastener Wet-Installation: Used for coating rivets, bolts, and hi-loks prior to installation to seal the fastener hole and prevent \"smoking rivets.\"\u003cbr\u003eFaying Surface Protection: Applied between overlapping aircraft skins, spar-to-rib joints, and stringer interfaces.\u003cbr\u003eAntenna \u0026amp; Exterior Fitting Seals: Provides a moisture-proof, non-curing seal for exterior-mounted hardware that requires periodic removal for inspection.\u003cbr\u003eNATO\/MoD Maintenance: Specified for aircraft maintenance where compliance with UK and European defense standards is mandatory.\u003c\/p\u003e","brand":"PPG Aerospace","offers":[{"title":"Default Title","offer_id":54578701959540,"sku":"JC5A60Z","price":382.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0888\/2991\/9604\/files\/JC5A60Z.png?v=1779134049","url":"https:\/\/145.aero\/products\/ppg-aerospace-jc5a-jointing-compound-nsn-8030-14-567-1753-160-ml-cartridge","provider":"Aircraft Shop Supply","version":"1.0","type":"link"}
