Level 2 Water-Based, Water-Washable 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 which may allow its rinse water to be disposed of directly into the sewage system depending on local regulations.

The penetrant features great rinse characteristics, and depending on the application and specification may be used without a developer.

ZL-440 is designed with environmental health and safety in mind while meeting industry performance standard approvals, including EN ISO 3452-2 and AMS 2644, and can be used in similar applications as other conventional Level 2 water-washable fluorescent penetrants.

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 waterbased 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.

WATER CONTENT & BATH MAINTENANCE

Refer to ASTM E1417 Section 7.8.2.3 for guidance on managing water content of A(w) penetrants. Due to the nature of water-based penetrant formulations, water loss may occur over time depending on environmental conditions. We recommend taking an initial refractometer reading to set a baseline, and then sample and measure the water content of your penetrant tank over time as needed based on specifications using the same refractometer process. If your penetrant tank sample is out of the recommended water content range, we recommend adding additional fresh penetrant to the tank to bring the water content back within the range. If the water content is below the recommended range, deionized water can also be added to increase water content; however be sure to mix the tank contents sufficiently after water addition to ensure full incorporation.

We recommend using a refractometer or similar measurement tool to measure the water content. Other common methods can also be used, such as Karl Fischer analysis. Note that the provided Brix and refractive index measurements for each product were measured using a refractometer under Magnaflux lab conditions, and customer readings may vary due to differences in refractometers and environmental conditions impacts on measurements.
