Glycolic acid is a great choice for metal cleaning because of its dual functionality to act as an acid and/or an alcohol. It's useful in a wide variety of metal cleaning applications including equipment, stainless steel boilers, heat exchangers, and many other industrial metal surfaces.
GLYCOLIC ACID IN METAL CLEANING APPLICATIONS:
Aluminum and copper cleaner and finishing
Electroless platin premix
Anodizing and sealer formulations
Pickling and mill scale
Acid cleaning and degreasing
Buffing compound cleaner
Relatively strong organic acid
4% solution of Glycolic Acid in water is below 2.0 pH.
Little corrosive fumes evolve on heating; low acid yield loss is experienced, even when solutions are used, non-VOC due to low vapor pressure.
Very mild odor
Does not fume as some mineral acids do.
Provides good rinsing properties
Dissolves carbonate, oxide, and most casein scales readily resulting in water-soluble salts.
Supplied in complete solution
Easy to handle as a liquid; no "incomplete dissolving" problems; 70% concentrate can be quickly diluted to any desired strength within water.
Relatively low corrosion
Low rates of corrosion can be further reduced by addition of a corrosion inhibitor.
Contains essentially no chlorides
Can be used for cleaning stainless steels without the possible chloride cracking or embrittlement sometimes experience in acid chloride systems.
Compatible with many cleaning additives
These can include surfactants, biocidal agents, corrosion inhibitors, scents, colors, other acids, and, of course, water.
Contains complexing properties
This characteristic may preclude the need to add a special chelating or complexing agent and enhances the rinsibility property of the cleaner.
Relatively safe to store and handle
Always be sure to follow the safety data sheet guidelines.
Does not support growth of bacteria in use.
Why Chemours Glycolic Acid?
No chloroacetic acid - chloride free
Low corrosivity and VOC free
Safe & easy to handle
Very mild odor versus other acids' strong odor
Dual activity with rust and scale removal
Safe to use on aluminium, copper, steel and many other metal types and alloys
16.8% less corrosive to carbon steel
Glycolic acid from Chemours is over 14 times less corrosive to copper and almost 30 times less corrosive to stainless steel.
Glycolic acid from Chemours is over 300 times less corrosive to aluminum surfaces compared to other competetive glycolic acids.
