FAQs

What are the applications for EnviroStrip® products?
  • Removes aircraft paint, primer and various aerospace coating materials from thin aluminum, composite and other sensitive substrates
  • Removes excess adhesive flashing from thin-skin bonded parts
  • Selectively removes polyurethane top coat paint leaving the epoxy primer intact
  • Serves all coating removal requirements demanding minimal substrate effects and/or damage
What is EnviroStrip wheat starch media?
  • EnviroStrip wheat starch media is made from wheat starch, a 100% natural, renewable resource. This non-toxic, non-petroleum based abrasive product is designed and engineered specifically for coating removal applications
  • EnviroStrip is manufactured in various grit sizes to accommodate various coating removal requirements
  • EnviroStrip is a biodegradable, organic material, manufactured to high purity standards
  • Wheat starch media has broad approval for use on aerospace aluminum and composite structures and is used throughout the aerospace industry as a primary coating removal process
What is EnviroStrip XL corn hybrid polymer?
  • XL’s moisture resistance and good flowability allow it to be used in all types of plastic media equipment without modifications  
  • Corn hybrid polymer was specifically engineered as a paint-removal abrasive media for delicate aircraft surfaces
  • XL is ideal for removal of most polyurethane topcoat and epoxy primer paint schemes from metal or composite surfaces
What is eStrip® GPX starch-g-acrylic?
  • eStrip series are engineered copolymer media derived from grafting starch with acrylic plastic. eStrip™ media are classified as starch-g-acrylic media and are manufactured to meet the USAF MIL-P-85891A requirement for Type VII media
  • eStrip series medias are designed to replace plastic media, especially when there are concerns about surface alteration and or damage often related to the use of plastic abrasive
  • eStrip GPX is corn starch hybrid and acrylic based product which exhibits mechanical properties similar to other starch abrasives and is suitable for metallic and certain composite substrates
  • eStrip GPX offers several advantages, including longer product life (reduced consumption rates) and UV florescence to assist post-stripping inspection
  • eStrip GPX is moisture resistance and good flowability allow it to be used in all types of standard plastic media equipment without modifications

What process parameters are recommended for stripping metal substrates?

Nozzle pressure:
Media flow:
Nozzle distance from surface:
Impingement angle:

25 - 40 psi
10 - 16 lb/min
4 - 12 inches
40 - 60 degrees

What process parameters are recommended for stripping composite material?

Nozzle pressure:
Media flow (1/2" Nozzle):
Nozzle distance from surface:
Inpingement angle:

20 - 30 psi
10 - 16 lb/min
4 - 18 inches
20 - 40 degrees


Are flat nozzles more efficient than conventional round blast nozzles?
For most applications, flat nozzles will outperform round nozzles. Flat nozzles have been known to double the paint removal rates in certain manual stripping applications. The flat nozzle’s ability to evenly distribute the media particles across the nozzle width delivers superior performance over round nozzles. This results in less media consumption per part or area stripped.

How do I change my facility from using plastic media to an EnviroStrip product?
Minimum Requirements:
  • Dry Air: Compressed air should be clean and dried to a 40 degree pressure dew point
  • Dust Separation: A large media mesh-size range is required for Envirostrip. Change vibratory screens and/or adjust cyclones to allow media in the 12 to 100 mesh size to be returned to the storage hoppers
Other Recommendations:
  • Positive displacement media feed valves: allows for accurate media flow and high flow rates if needed (16+ lb/min)
  • 70 degree angle or incline on all storage hoppers and pressure vessels
  • New media make-up feeder: provides new media to system as dust/fines are removed
What process guidelines are recommended when using EnviroStrip® wheat starch media?
• See Process Guidlines

What precautions should be taken to safeguard against dust ignition?
While the EnviroStrip products are more difficult to ignite than most other blast abrasives (including plastic media), adequate ventilation is always required. A properly designed and built ventilation exhaust system, dust collector and fresh air make-up must be used. Precautions should be taken to minimize any build-up of dust inside the blast area. Minimize horizontal surfaces where dust can collect. Daily housekeeping (dust removal) rules should be followed. Any source of ignition and/or fire must always be controlled. Consult with local and State Laws, EPA and OSHA regulations. Contact ADM for detailed explosibility test data.
