ZL-425
Water-Based Fluorescent Penetrant
ZL-425 is a water-based, water washable fluorescent penetrant used for finding indications in castings, forgings, extrusions and other materials with rough surfaces commonly found in automotive part applications. ZL-425 is an ideal solution when waste water produced during the inspection process is a concern for the operation. ZL-425 is water based and contains no petroleum distillates allowing it to drain directly into the sewage system depending on local regulations.
ZL-425 has been specifically developed for use within the automotive sector and can also be used in applications where traditional petroleum solvent-based penetrants may attack the surface, such as plastics. The penetrant features great rinse characteristics allowing it to be self-developing, so you may not need to use a separate developer depending on the application.
ZL-425 is designed to be environmentally sensitive while meeting industry approvals, including EN ISO 3452-2 and AMS 2644, and can be used in place of any conventional water-washable fluorescent penetrant.
