AmberClean™ 527MF is a biodegradable, aqueous nickel disk cleaner which does not contain volatile organic compounds (VOCs). It is specifically formulated to flush and disperse nickel fines and process contaminants from substrate surfaces in disk cleaning applications. Additionally, the surfactant technology employed by AmberClean 527MF is designed to cut through and remove aluminum oxide/colloidal silica slurries and process chemicals from nickel and glass substrates without leaving films or residues. This formula should be diluted with deionized water and can be used in soak tanks, ultrasonic tanks and contact cleaning systems, in addition to high pressure spray cleaning equipment.
