CHALLENGE 800 series products are water-based, ultrasonic/megasonic detergents formulated to increase the cavitational energy released upon substrate surfaces for more effective cleaning. Used at economical dilution ratios, CHALLENGE 800 series products will remove light organics and sub-micron particles. They are typically used to remove post-process residues after grinding, slicing, lapping, etching, and polishing. CHALLENGE 800 series products can be used in heated or unheated ultrasonic tanks, and are also recommended for brush and dip tank applications.
