Complex checks are a mandatory part of aircraft heavy maintenance in aerospace MRO, but MRO companies are still challenged to limit aircraft downtime. Each stage of the MRO operation has an active role and doesn’t want to waste time, especially during sealant removal operations!

SOCOMORE understands the issues facing MRO operators and offers a full range of sealant removal solutions to simplify and speed up operations.

Our fluted SkyScraper range of scrapers are resharpenable and specially designed to fit the SkyMill­™ Revolution and SkyEdgit sharpening devices, meaning they can be used for longer as they retain their sharp cutting edge. The SkyGrip, suitable for use with all SkyScraper scrapers, is an interchangeable comfortable rubber grip that reduces and prevents injuries such as carpal tunnel syndrome.

How are sealants removed in aerospace operations?

First, the operator removes the old sealant with a scraper. The surface is then cleaned with a solvent or water-based pre-saturated wipe to remove any residue. After this, the surface is cleaned again so it is ready for sealant to be reapplied.

One range for all sealant operations

Sealant removal operations

SkyScraper scrapers remove cured adhesives and sealants without damaging the surface. For optimal use, they are available in different materials, shapes and sizes to suit a variety of applications.

“The main advantage of SOCOMORE fluted SkyScraper scrapers is that they can be resharpened at point of use with our sharpening devices, meaning they constantly have a sharp cutting edge compared to traditional disposable scrapers. They can be resharpened up to 20 times” explains Benoît Côte, Product Manager at SOCOMORE.

The fluted SkyScraper range is available in 2 materials:

  • POM (311 series): softer material that offers greater flexibility, white in colour.
  • ULTEM (310 series): tougher material, amber in colour.

Both the POM and ULTEM SkyScraper range are available in 4 different sizes for precise sealant removal: 1.45” (37 mm), 0.98” (25 mm), 0.55” (14 mm) and 0.12” (3mm).

Accessories

Portable sharpening devices

During use, scrapers become blunt and ineffective. Fluted SkyScraper scrapers have an extended lifespan thanks to the SkyMill­™ Revolution and SkyEdgit sharpening devices.

SkyMill­™ Revolution

The battery operated SkyMill­™ Revolution sharpening device is compatible with the 310 and 311 series fluted SkyScraper range. The machine is:

  • Portable
  • Rechargeable
  • Lightweight

With the SkyMill­™ Revolution, a fluted Skyscraper can be resharpened up to 20 times for continuous productivity and reduced waste.

“Remove any residual dust generated by sharpening from the scraper with SOCOMORE’s water-based pre-saturated wipes before using the SkyScraper again to avoid cross-contamination.” advises Benoît Côte.

SkyEdgit

The SkyEdgit is a handheld manual device that keeps the scraper’s cutting edge sharp. The device is compatible with the 310 and 311 series fluted SkyScraper range. As the SkyEdgit is designed for use at point of use, operators don’t need to leave their work station, increasing productivity.

Handles & Grips

SOCOMORE offers a range of ergonomic accessories for operator comfort and safety.
