AD‑AS4 Acetal Aircraft Sealant Scraper with Handle for Precision Rework & Surface Preparation
The AD‑AS4 Acetal Scraper features a convenient 0.98" (25mm) working area10.50" (268mm) handle for improved grip, leverage and operator comfort. Designed specifically for aircraft sealant removal and rework, it is ideal for use on pressurised fuselage skins, lap joints, butt joints and other sensitive areas such as antenna cut‑outs, wing‑to‑body fairings and window forgings.
Manufactured from a Boeing and Airbus‑approved semi‑crystalline thermoplastic, the scraper provides excellent pliability, strength and chemical resistance. Its non‑marring material ensures safe use on bare alclad aluminium airframes and composite surfaces, eliminating the risk of scratches, scoring or structural damage.
The luminous red colour ensures high visibility in aerospace environments, reducing FOD (Foreign Object Debris) risk and improving quality control. Side edges are smooth‑finished for comfortable use during extended maintenance or rework tasks.
In addition to aircraft sealant removal, the AD‑AS4 scraper is suitable for removing decals, stickers, loose paint and surface contaminants where metal tools may cause damage. AD‑AS4 and AD‑AS5 scrapers are robust enough to be used as wedge tools or light support tooling where scratch‑risk must be avoided.
All AD‑AS series scrapers undergo a strict 3‑step QA/QC process to ensure consistent quality. AD‑AS1, AD‑AS2 and AD‑AS3 scrapers have been tested to Boeing Standard BSS7384. Full test reports are available on request.

Frequently Asked Questions (FAQ)
Q: What makes the AD‑AS4 scraper suitable for aircraft use?
It is manufactured from a Boeing and Airbus‑approved semi‑crystalline thermoplastic, offering strength, pliability and chemical resistance while preventing scratches or scoring on aluminium airframes.
Q: Why does this scraper have a handle?
The extended handle provides better grip, leverage and control, making it ideal for removing tougher sealant deposits or working in awkward areas.
Q: Can this scraper be used on pressurised fuselage skins?
Yes - it is specifically designed for pressurised fuselage exterior surfaces, including lap joints and butt joints.
Q: Is the scraper safe for bare aluminium?
Absolutely. The acetal material is non‑marring and safe for bare alclad aluminium and composite substrates.
Q: What other tasks can the scraper perform?
It is ideal for removing decals, stickers, loose paint and surface contaminants without damaging the underlying structure.
Q: Can the AD‑AS4 be used as a wedge or support tool?
Yes - AD‑AS4 and AD‑AS5 scrapers can be used as wedge tools or light support tooling where metal tools may risk scratching aluminium substrates.
Q: Why is the scraper coloured red?
The luminous red dye ensures high visibility in aerospace environments, reducing FOD risk and improving quality control.
Q: Has the scraper been tested to aerospace standards?
AD‑AS1, AD‑AS2 and AD‑AS3 scrapers have been tested to Boeing Standard BSS7384. Full test reports are available on request.
Q: Is the scraper silicone‑free?
Yes - it is silicone‑free, making it suitable for sensitive aerospace and manufacturing environments.
