AQUANOX A4703 is a pH neutral cleaning solution that will remove no-clean, rosin and water-soluble flux residues from printed circuit assemblies. A4703 can be run in both batch and inline spray-in-air cleaning machines at comparably low concentrations and low temperatures equaling a lowered operating cost while maintaining its environmentally friendly nature.

As a pH neutral formulation, AQUANOX A4703 utilizes KYZEN’s revolutionary inhibition technology and is a low foaming solution. This combination delivers superior material compatibility and pristine parts. A4703 is easily controlled by the refractive index, contains no hazardous materials and is low in odor.
