ABSTRACT:
Chromogenic solvent detectors are used to detect and map the presence of organic solvent-containing materials on a surface. The detector need only be applied to the surface to be tested. When removed, the dark areas on the detector correspond to those areas of the surface where an organic solvent-containing material was present. This method can be used to test the release properties of a release film.
