In electrocoating and plating processes, objects are dipped into process tanks and painted by means of electrophoretic deposition.  During the process, paint particles are suspended within a liquid medium and have a charged placed upon them. Under a high voltage DC current, the paint particles migrate to the part being painted and are deposited onto the surface, resulting in a highly corrosive resistant and durable paint film. The part is then rinsed several times, and the rinse water counter flows back to the main paint tank.

Synder Filtration is proud to be a leading supplier of technology across this entire process.  See below for our most common applications. 

OUR MOST COMMON APPLICATIONS 
Paint Tank Acid Removal
Synder manufactures two types of anolyte cells, which cater to paint tanks of all sizes and configurations.  The tubular TechCELL, and c-shaped SuperCELL both perform the crucial function in the electrocoating process of removing excess acid generated during electrolysis, which is essential to keep the paint chemistry in balance. 

Anolyte Fluid Recirculation
While anode cells remove acid from cleaner baths, the anolyte solution running through the cells must be recirculated to prevent corrosion in the anode cells and ensure the balance of paint chemistry in the bath.  Synder’s Anolyte Recirculation Systems are fully customizable to any paint bath and ensure that anode cells work at maximum efficiency. 

Paint Purification & Concentration
After a coating process, paint must be purged of all extraneous materials before another object can be painted.  Synder’s Ultrafiltration systems have become the standard across the electrocoating industry for this process.  By processing the paint solution with Synder’s V6 or A6 elements (specifically designed for the electrocoating process) and removing all unwanted materials, our Ultrafiltration systems return purified paint to bath, which is ready for the next coating process. 

Ultrapure Water for Final Rinsing
Final rinsing of coated objects is essential to ensure readiness for subsequent stages of painting.  Ultrapure water is required for this stage since any impurities in the water can leave substances on surfaces that can compromise the entire painting process.  Synder’s Reverse Osmosis systems are specifically designed to produce water with the level of purity required for final rinsing.  With an extensive history of manufacturing and integrating systems into a variety of electrocoating processes around the world, we’re ready to take on your challenge.
