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.

One Stop Shopping

CPI can recommend pumps, meters, and other control equipment. If desired, we can provide these items directly to ensure your service experience is friction-free.

Peace of Mind

If you have a problem anytime, day or night, you can get in touch with a technical service representative. Just call our general office number at (812) 339-3653. After normal business hours, a paging system will guide you.
