Why Manufacturers Choose CPI
The Cost of Low-Cost is High
Trying to save a few cents usually leads to rework, cleanup, and lost time. CPI helps you avoid the fallout of short-term fixes.
Our Fast Track Innovation
Here at Circle-Prosco we prototype in weeks, not quarters -so you can launch faster, pivot quickly, and meet tight production deadlines.
From Chemistry to Manufacturing
We tailor every formula to your actual process – not just a spec sheet. Our team works hands-on to get it right on your line.
Green Chemistry Without Headaches
Meet VOC and sustainability mandates without switching to underperforming alternatives. We help you reduce emissions.
When A Cure Issue Threatened Delivery
A powder coat cure delay put a major appliance launch at a Tier 1 manufacturer at risk. Circle-Prosco diagnosed the problem, fixed it fast, and got production back on track.

How is Circle-Prosco different from other chemical suppliers?
We’re not just selling formulas. We partner directly with your team to tailor solutions that work with your specific line—not just your industry. Our chemistry is built to perform in the real world, not just on a spec sheet.
Is your chemistry compatible with existing paint lines?
Yes. Most clients can integrate Circle-Prosco chemistries—like Steelcote™—with minimal downtime. Many remove rinse stages or replace inefficient tanks without overhauling their full system.
What industries do you serve?
We work across wide range of industries, including HVAC, automotive heat exchangers, agricultural equipment, and appliance manufacturing—tailoring chemistry for each line’s specific needs.
What is the Solution Squad?
Our on-call team of experts who know your process, not just the product. They’re available to troubleshoot issues fast, optimize performance, and make sure things run right—on your schedule, not ours.
Do you offer training for our team?
Yes. Paint Line University gives your operators and engineers practical tools to spot issues early and solve them fast—so troubleshooting doesn’t turn into downtime.
