Atotech has recently broadened its paint stripping processes with Recover, a part reclamation technology for the effective removal of organic coatings from high-value parts.

 

When paint defects occur on high-value automotive components such as aluminum wheels, aluminum roof rails, window guides or galvanized door pillars, 100% paint removal is required prior to reprocessing.

 

Mechanical stripping methods will degrade polished surfaces and could change component dimensions. While molten salt technologies are fast acting, they can change metallurgical properties due to their operating temperatures. Traditional chemical stripping is often incomplete, unpredictable and could unevenly etch substrates such as aluminum and zinc.

 

Highly volatile chemicals, such as methylene chloride, are prohibited by strict environmental regulations. Stripping with sulfuric acid solutions is not acceptable for many automotive OEM’s due to surface etching, potential metal loss and the subsequent loss of coating performance.


Today, critical safety components such as aluminum wheels are sometimes stripped in sulfuric acid despite the risks. OEM’s that permit sulfuric acid stripping must rely on their Tier 1 suppliers and their sub-contractors to strictly monitor and manage sulfuric acid’s impact.


Recover is a sustainable paint stripping process designed to provide consistent etch-free performance even with the most delicate components. According to Atotech, it effectively removes fully cured powder, wet applied paints, e-coat, and multi-layered coating systems from all metal surfaces and has been specifically designed for processing aluminum and zinc.

 

Recover is said to provide undamaged, fully stripped surfaces that are ready for rework after just one application. Since polished areas remain undamaged after stripping in Recover, expensive re-polishing or machining are unnecessary.


Recover is globally specified by Ford Motor Company and has been available in North America for more than five years. In 2010 Atotech signed a global production and sales agreement with Kolene assuming distribution responsibilities for the patented Recover technology.
