AD‑AS3 Dual‑Head Acetal Aircraft Sealant Scraper for Precision Rework & Surface Preparation

The AD‑AS3 Acetal Scraper features a dual‑head design with 0.28" (7mm) and 0.79" (20mm) working areas, providing exceptional versatility for sealant removal, rework and tidy‑up on critical aircraft structures. 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 offers 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 provides high visibility in aerospace environments, reducing FOD (Foreign Object Debris) risk and improving quality control. Side edges are smooth‑finished for operator comfort during extended use.

In addition to aircraft sealant removal, the AD‑AS3 scraper is suitable for removing decals, stickers, loose paint and surface contaminants where metal tools may cause damage.

All AD‑AS1, AD‑AS2 and AD‑AS3 scrapers undergo a strict 3‑step QA/QC process to ensure consistent quality. These scrapers have been tested to Boeing Standard BSS7384. Full test reports are available on request.

Frequently Asked Questions (FAQ)

Q: What makes the AD‑AS3 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 two working ends?

The dual‑head design provides greater versatility, allowing operators to switch between narrow and wide working areas for different sealant removal tasks without changing tools.

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: 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?

Yes - AD‑AS1, AD‑AS2 and AD‑AS3 scrapers have been tested to Boeing Standard BSS7384. Full test reports are available on request.

Q: What pack sizes are available?

Scrapers are supplied in sealed packs of 10, suitable for both small workshops and large‑scale MRO operations.

Q: Is the scraper silicone‑free?

Yes - it is silicone‑free, making it suitable for sensitive aerospace and manufacturing environments.
