About this product
ROCOL Flawfinder Developer Spray is an aerosol-applied white powder coating used in non-destructive testing to detect surface cracks and flaws not visible to the naked eye. It forms a highly absorbent white film that draws penetrant dye out of any surface defects, enhancing contrast and definition for clear, rapid detection. It is intended for use as part of the three-stage Flawfinder inspection system, alongside Flawfinder Dye Penetrant and Flawfinder Cleaner sprays. Suitable for inspecting welded joints, castings and forgings where structural integrity matters, as well as for pressure testing and leak detection in workshops, fabrication shops and industrial facilities. Supplied as a 400ml aerosol for convenient application.
