Do all powder coating companies utilize the same pretreatment process?
No. ACL differentiates itself from the competition due to its superior pretreatment process. ACL pretreatment for aluminum is world class. ACL utilizes a state of the art six stage pretreatment process, which exceeds AMMA 2604-02 standards. ACL is unique in that its production lines are specialized into separate steel and aluminum lines utilizing specialized chemicals. Most of our competition utilizes a three stage wash on a combined steel and aluminum line which does not provide the quality separate lines afford. In addition ACL utilizes a six stage iron phosphate wash with reverse osmosis rinse which provides superior cleaning, better conversion coating weights deposited to the substrate and a clean rinse with ultra clean. This provides our customers the best possible adhesion and corrosion resistance.
