ISSUE NO. 5 Your Line Deserves a Little Less Drama.

Pretreatment is supposed to be simple.

Set it up. Run the line. Parts come out ready to coat.

That’s the promise, anyway.

But the more complicated the chemistry, the more attention it demands. Extra checks. Extra adjustments. Extra eyes on the process just to keep things steady. 👀

At CPI, we designed Steelcote™ to do one thing: take the complexity out of pretreatment.

Steelcote™ Zirconium is our phosphate-free pretreatment chemistry, proven to stay consistent across shifts and reliable under real production demands.

Steelcote™ keeps pretreatment simple, steady, and—best of all—drama-free. Just give us the word and we’ll walk you through what it could look like on your line. Get in Touch.

How Steelcote™ Keeps Pretreatment Drama-Free

Every washer has its limits. Add too many variables—extra checks, constant corrections, heavy sludge—and the process starts stealing time instead of saving it. What should run quietly in the background ends up demanding more attention.
That’s why the details matter. Pretreatment has to stay clean, predictable, and easy to manage if it’s going to keep pace with the rest of the line.
Here’s where Steelcote™ makes the difference:
1. Pretreatment in just 3 or 4 stages
Steelcote™ doesn’t require extra tanks or long stage counts. The process runs clean in just three or four stages, making it simpler to move away from phosphate without overbuilding the line.
4-Stage: Keeps cleaning and coating separate, making it a good fit when parts come in with heavier soils or mixed metals.
4 Stages (19)

3-Stage: Combines cleaning and coating in one step, best suited when soils are lighter or when space and operator time are limited.

2. Sludge-Free, Phosphate-Free

Phosphate systems generate heavy sludge that clogs washers, eats up operator time, and racks up hauling bills. Steelcote™ eliminates it completely by running phosphate- and heavy metal–free. No sludge. No sealer stage. No hazardous waste to manage. Just a cleaner process from start to finish.

3. Stable Across Shifts

Production rarely looks the same from one shift to the next—soil loads vary, operators rotate, and throughput changes with the season. Steelcote™ keeps pretreatment stable under those real-world conditions. Baths are managed with simple titration checks, no additives required, so performance holds steady even when production isn’t.

4. OEM-Validated Performance

Passing in a lab is one thing. Passing on the line is another. Steelcote™ has been validated in both agricultural and automotive supply chains, consistently meeting corrosion and adhesion requirements under OEM standards.

5. Longer Bath Life, Less Waste

Steelcote™ extends bath life to 6–12 months, reducing the number of cleanouts and the volume of chemistry needed. It also uses up to 60% less water than phosphate systems, lowering operating costs and cutting waste treatment. Less downtime. More uptime.

A Closer Look at the New 3-Stage Option

We touched on it above, but CPI’s newest zirconium solution deserves its own spotlight. Steelcote™ 1750 is our latest pretreatment solution, combining cleaning and coating into one stage to deliver a true phosphate-free 3-stage process.

3-Stage Setup: Steelcote™ 1750 Cleaner/Coater → Rinse → Rinse

Why it matters:

  • Simplifies the washer layout with fewer tanks and less floor space
  • Eliminates phosphate sludge and HAZMAT waste
  • Easy to manage day-to-day with simple titration checks
