AESUB blue is a self-vanishing scanning spray developed by scanning experts. The spray evaporates within a few hours, meaning that there is no need for cleaning after scanning. Unlike traditional sprays, AESUB blue does not contain pigments and thus avoids pigment contamination of sensitive areas, such as laboratories and production sites, equipment, and users. You can therefore apply AESUB blue directly, on the spot of scanning, without any costly transport to avoid said pigment contamination in sensitive areas.
