Pre-Treatments Overview
DuPont™ 13204S™ Aluminum Alloy and Metal Cleaner
DuPont™ 13204S™ provides deep cleaning and conditioning of metal surfaces in preparation for a subsequent conversion coating. This step is commonly referred to as acid etch treatment DuPont™ 13204S™ is recommended for high copper aluminum alloys where DuPont™ 13205S™ is not recommended. View PDF Technical Manual

DuPont™ 13205S™ Aluminum Cleaner
DuPont ™ 13205S™ provides deep cleaning ,brightening, and conditioning of aluminum surfaces in preparation for a subsequent conversion coating. This step is commonly referred to as acid etch treatment. DuPont™ 13205S™ should not be used on high copper bearing aluminum alloys (e.g. 2024) or aluminum castings. View PDF Technical Manual

DuPont™ 13206S™ Aluminum Conversion Coating
DuPont™ 13206S™ provides a chromate conversion coat on aluminum and aluminum alloys. The coating formed by DuPont™ 13206S™ is gold to tan in color and provides for adhesion of subsequent primer as well as corrosion protection. DuPont™ 13206S™ Aluminum Conversion Coating is recommended as part of an aluminum pretreatment system with either DuPont™ 13204S™ Aluminum Alloy and Metal Cleaner or DuPont™ 13205S™ Aluminum Cleaner.
