Description
ZL-425 - Water-Washable and Water-Based Fluorescent Penetrant - Level 1
ZL-425 is a water-washable, water-based fluorescent penetrant used to detect indications in castings, forgings, extrusions, and other materials with rough surfaces commonly found in automotive parts applications. ZL-425 is an ideal solution if wastewater generated during the inspection process is a concern for the operation. ZL-425 is water-based and contains no petroleum distillates, allowing the wash water to be discharged directly into the sewer system, depending on local regulations.
The penetrant exhibits excellent water-washability and is self-developing, meaning a separate developer may not be necessary, depending on the application.
ZL-425 is designed to be environmentally sensitive, meeting industry approvals, including EN ISO 3452-2 and AMS 2644, and can be used in place of any conventional water-washable fluorescent penetrant.
Benefits
Reduces environmental impact and wastewater pollutants
- Reduce water treatment costs and dispose of wastewater directly into the sewer system (depending on local regulations) thanks to the minimal water-based contaminant content.
- Meet or exceed local regulations for disposal with low Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) levels.
- Promote a healthy environment with water-based penetrants that have minimal impact on occupational health and safety.
Reliably accelerate inspection and washing processes
- Identify bright indications with superior sensitivity and low fluorescent background interference.
- Increase throughput and reduce costs by eliminating the developer step from the inspection process, depending on procedures and requirements.
- Quickly rinse and wash parts after inspection thanks to excellent washing characteristics, thanks to proprietary chemical technology.
