Product Data Sheet – ZYGLO ZR-10C
ZYGLO® ZR-10C is a hydrophilic emulsifier used (diluted in water) as the remover/emulsifier in post-removable penetrant systems. It is designed to reduce fluorescent background from penetrants on rough surfaces, as well as reducing bleed-out of penetrant from hollow parts.
ZR-10C yields reliable and reproducible test results from post-emulsifier penetrants.
- Reduces bleed-out on hollow parts
- Reliable results
- Usable in a wide range of concentrations
- Excellent control over removability

In cold storage conditions, ZR-10C may appear cloudy. This is due to the type of surfactants used and is normal for this type of product.
Like all Magnaflux materials, ZR-10C is closely controlled to ensure batch-to-batch consistency, optimum process control and inspection reliability.

|Usage temperature||15°C to 55°C|
Instructions for Use
ZR-10C needs to be diluted with water before use, normally at a 5% – 20% concentration.
Immersion dip method:
- Pre-clean the test part.
- Apply penetrant and allow contact time.
- Spray with clean water for 15-30 seconds.
- Immerse part in the emulsifier bath for required time (normally 30 – 120 seconds).
- Drain the part, then rinse with water
- Allow to dry
- Apply developer
- Inspect part
- Post-clean with a clean water spray to remove any penetrant/emulsifier residues.
When using ZR-10C, you will need to regularly agitate the bath during use, and check the concentration to ensure that the established working strength is maintained. This can be achieved by the use of a suitable refractometer and a concentration chart. To create a ZR-10C concentration chart:
- Select three to five accurately known samples (e.g. 5-10-15-20-25% ZR-10C) that have been carefully measured and mixed.
- Take readings of the known samples using the handheld refractometer.
- Plot a chart with the refractometer readings on the vertical y-axis and the known % ZR-10C values on the horizontal x-axis.
The water content of the bath can also be determined using the procedure described in ASTM D-95.
ZR-10C can also be diluted and applied as a spray. For spraying, the usual concentration range is 0.1% to 0.5%; however, you can use a maximum concentration of 5% depending on the application.
