There are a variety
of abrasive strippers available on the market today. These offer the benefit of removing the chemical component from the de-painting process. In addition, some of them can be safely used on composite structures. One factor that needs to be kept in mind when working with abrasive strippers is migration of the media. All open areas of the aircraft should be masked to prevent the media from getting into areas of the aircraft that would be detrimental.
There are varying types of media available to remove paint. A number of manufacturers offer plastic media. ArmaKleen offers a sodium bicarbonate product for abrasive blasting. Wheat starch has even been developed for use by ADM/Ogilvie and is marketed as EnviroStrip.
Laser paint removal
A new technology in the area of paint removal is the use of lasers. General Lasertronics Corporation has developed a laser application for surface cleaning and de-painting. The system has a self-contained waste capture and disposal system and can be manually or robotically operated. The company has developed a portable unit by delivering the laser beam to the work surface through fiber optic cables with an attached workhead. The workhead can be as much as 150 feet from the laser source.
In a laser-based paint removal system, a pulsed laser beam is directed onto the surface at a calculated energy level. It breaks down the paint and primer coatings and produces a minimal waste stream.
Ultimately, there are many factors to be considered when selecting a paint stripping method. Although the costs for materials and equipment may be easy to determine, other factors come into play such as production rates, flow times, labor rates, facility requirements, and waste disposal.
In the end, the each stripper needs to be evaluated on a case-by-case basis. What might work well for one facility may not work well for another. All factors such as cost, ease of use, exposure danger, and disposal methods need to be factored when choosing a paint stripping product.
