Frequently asked questions
- What types of aerospace sealants does Angad Aviation supply?
- Our sealant range covers integral fuel-tank sealants, corrosion-inhibitive sealants, RTV silicone, two-part (base-and-accelerator) sealants, firewall and firebarrier sealants, electrically conductive sealants, and gasketing and threadlocking sealants. Tell us the specification you work to and we'll match the right product.
- Which specification covers aerospace fuel tank sealant?
- Integral fuel tank sealants are polysulfides made to stay sealed under continuous fuel immersion. The specifications most often seen are AMS-S-8802 (the successor to MIL-S-8802) and AMS 3276; low-density grades are covered by AMS 3281. The suffix gives the class and application life: Class A is brushable, Class B is extruded for fillets and fastener seals, Class C is spread on faying surfaces, and B-2 means a Class B grade with about two hours to work.
- What is a low-density sealant?
- A low-density fuel tank sealant does the same job as a standard grade with a lighter filler, which matters because a tank holds a lot of sealant. The specification is AMS 3281. Low density is a property, not an approval: the sealant must still be qualified to the specification your maintenance data calls for.
- Are chromate and non-chromate sealants interchangeable?
- No. Chromate sealants use hexavalent-chromium pigments, and most sealant families now also offer a non-chromate version. The approval in your maintenance documentation is for a specific product, so a non-chromate substitute needs its own approval. If you operate into or out of Europe, check the regulatory position before standardising on a chromated product.
- Do parts from Angad Aviation come with certification and traceability?
- Yes. Where an authorized release certificate applies, parts are supplied with an EASA Form 1 or FAA Form 8130-3 and full traceability. With Angad Verified, that certificate carries a digital seal anyone can check online in seconds — no login required — confirming the copy they hold is the one we sealed, unaltered.
