Solution Squad

Circle-Prosco’s Solution Squad has been solving the gnarliest manufacturing problems for more than 50 years.


Our Solution Squad will work with you to determine the best chemistry for your unique processing needs. If you have unique or demanding requirements, we’ll even custom formulate a solution for you.


After formulating new solutions or selecting existing solutions, we will coat test parts and panels as part of our standard Solution Squad service. We can then perform numerous types of testing at our facility to quickly evaluate performance.


During a trial, the Solution Squad goes to your facility to make sure the process runs well. We run the trials according to your schedule, and we will even help you prepare your line.

Continued Support

After start-up, our Solution Squad isn’t done. We’ll evaluate your process on a regular basis, ensuring that it continues to run well. We also provide training for operators and engineers.

Mike Clements, Operation Manager

Kingfisher Boats Inc

“The team at Circle-Prosco are who they say they are and live up to their promises. When we described the challenges we were experiencing with our cleaning operation, CPI recommended a cleaner and developed custom application instructions specifically for our process. This solution resolved all our challenges and produced a better finish on our boats. With CPI’s chemistry we use much less cleaner than before, saving us money, while using a better product. We continually look for more Circle-Prosco products we can use.”

Plant Manager

Global Agricultural Equipment Manufacturer

“I have trusted Circle-Prosco for close to 15 years in my pretreatment process on several powder coat lines. We have a great working relationship as CPI has been valuable to improve our processes with great service as well. I look at CPI as a very reputable company that delivers and services our needs. To me CPI stands for Continuous Process Improvement!”


Leading Global Welding Manufacturer

“Our transition from iron phosphate to Steelcote™ was flawless. We resolved a longstanding problem of inconsistent corrosion test results by switching to this new technology. Circle-Prosco brought in a team of experts and followed the transition to the very end. The service has been exceptional, and their team is always ready to service our needs.”
