ZR-10B is a biodegradable, pinkish, slightly viscous liquid. ZR-10B is a 100% active concentrate, which is diluted in water when used as an emulsifier for Zyglo® PE penetrants. ZR-10B is very low in sulfur, chlorine, and sodium content.

Utilization of ZR-10B Hydrophilic Emulsifier affords such advantages as: minimization of fluorescent background on rough surfaces, minimization of bleed-out from hollow parts, reduced consumption of expendable materials, ease of use in closed loop systems and reduced effluent pollutants. ZR-10B Hydrophilic Emulsifier yields the most reliable and reproducible test results due to its controlled Zyglo® PE penetrant removal.
