Specially designed to reduce the cost of quality inspections, ZL-150 fluorescent water washable penetrant is ideal for finding indications in rough cast parts in high-volume dip applications. Foundries and casting houses will find this penetrant particularly useful in reducing cost while maintaining strong Level 2 fluorescent penetrant performance in sensitivity and removability.

This medium-sensitivity penetrant limits the amount of material retained on parts after dipping, also known as drag-out. Additionally, it washes off parts quickly and easily, leaving very little background fluorescence and reducing the time and amount of water necessary to deliver clear indications for reliable inspections.

ZL-150 is listed on the QPL SAE AMS 2644 Qualified Products List.
