Madison Chemical introduces ALUMA-BRIGHT FOAM, an acidic cleaner containing a balanced blend of surfactants and acids for cleaning and brightening aluminum alloys through a moderate etching process, including welds. This unique blend of surfactants and acids provide the ability to “wet out” the surface, as the surfactants help the acid penetrate the soils and tramp oxides and allows the liquid to flow across the topography surface well. This also helps to penetrate the various grain boundaries, inclusions, voids, and other imperfections in the surface well. Primarily intended for soak or foam applications, this unique product has a mild, pleasant odor. Ideal for subsurface cleaning and removal of subsurface staining. In addition to cleaning welds, it removes soil and scale buildup, rust blush, rust back, flash rust, and other forms of oxidation, lime, and other scale deposits from drain vestibules during the descaling of the bath stages or recirculating spray washers. It is also helpful in targeting laser scale, heat treat scale, weld marks, red oxides, aluminum smut, plasma smoke residues, and more.
ALUMA-BRIGHT FOAM can be used at 65°F to 180°F at concentrations of 1% to 10% by volume with water. Foam, immerse, wipe, scrub, or spray on metal then rinse thoroughly with water. Contact time will vary with soil loading and application. For optimum results when working with large surfaces, clean from the bottom-to-top to minimize streaking effects, then water rinse from the top of the part and work towards the bottom. Using a dedicated slow flood rinse motion with ambient to cool clean water, an operator can determine that soils and any acidic residual chemical residue are neutralized and rinsed away when a smooth water break free surface film is observed during rinsing.
Water temperatures below 90°F typically prevent dry down before all soils have been removed.
Madison Chemical Technical Sales Representatives are available to assist in determining dilutions, dwell time, standard operating procedures and more, to achieve optimal results.
It is recommended that pumps, tubing, fittings, and any other components which will be in regular contact with ALUMA-BRIGHT FOAM be constructed of or coated with Teflon®, Viton®, Kynar® (PVDF), polypropylene to 72°F, and polyethylene to 72°F.
