ZL-440

Magnaflux Water-Based Fluorescent Penetrant

    ZL-440 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-440 is an ideal solution when waste water produced during the inspection process is a concern for the operation. ZL-440 is water based and contains no petroleum distillates allowing it to drain directly into the sewage system depending on local regulations.

    ZL-440 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-440 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.

Features

• Level 2, medium sensitivity
• Hydrocarbon-free
• Biodegradable
• Excellent water wash removability
• Developer is not required

Benefits

Reduce environmental footprint and waste-water pollutants

• Reduce water treatment costs and discharge waste process water directly into the sewage system (depending on local regulations) due to minimal water-based contaminants.
• Meet or exceed local discharge regulations with low Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) levels.
• Support a healthy environment with water-based penetrants that have minimal occupational health and safety impacts.

Reliably speed up inspection and wash processes

• Identify bright indications with superior sensitivity and low fluorescent background interference.
• Increase throughput and reduce costs by eliminating the developer step of inspection processes depending on procedures and requirements.
• Rapid rinse and post inspection washing of parts thanks to excellent washability properties, due to trade secret chemistry.
