Paper Mill Roll Recoat Service
Paper mill roll recoat service from AEGIS Advanced. PTFE, PFA, and FEP fluoropolymer recoats for press rolls, dryer cans, calender rolls, breast rolls, and size press rolls. Workshop coating in Elkton, Maryland, or field deployable so your mill stays in line.
When a roll needs recoating
- Visible release failure (sheet picking, web breaks, edge curl)
- Coefficient of friction has drifted out of spec
- Surface pinholes letting moisture into the substrate
- Corrosion underneath the original coat
- Original coating has worn through to base metal
- You are switching grades and the existing release no longer fits
Before and after on a dryer can recoat
What we recoat
| Roll type | Typical coating system | Why we use it |
|---|---|---|
| Press rolls (rubber and composite) | PTFE primer plus PFA topcoat | Release plus chemical resistance |
| Dryer cans (cast iron) | PFA at 4 to 6 mil | Sheet release at 180 plus degree surface temperature |
| Calender rolls (steel) | FEP at 2 to 3 mil | Gloss control plus release |
| Breast rolls and size press rolls | PTFE with conductive filler when needed | Release plus static dissipation |
| Spreader rolls and idlers | PTFE at 1 to 2 mil | Wear and release |
How the recoat process works
- Inspection and quote. Send us drawings, photos of the wear, and the existing coating spec if you have it. We quote within 48 hours. Every recoat is individually quoted because rolls are custom. We do not publish pricing.
- Strip. Existing fluoropolymer is removed mechanically and thermally. We do not use halogenated strippers near mill equipment.
- Surface preparation. Grit blast to white metal at the right anchor profile for the system being applied. Profile is measured, not guessed.
- Prime. PTFE primer applied wet, flashed, then partially cured.
- Topcoat. PFA, FEP, or PTFE topcoat applied in controlled passes to hit the target film build.
- Cure. Programmed cure schedule based on the topcoat resin. Verified with surface thermocouples.
- Inspection. Film thickness measured at minimum 12 points. Continuity tested. Surface release checked against the original spec.
- Ship or reinstall. Workshop jobs ship FOB Elkton. Field jobs are reinstalled by our crew and signed off with the mill maintenance lead.
Field deployable recoating
When pulling a roll out of the machine is not practical, we bring the recoat to you. Our field crew has done recoats in operating tissue, kraft, and specialty paper mills across the eastern United States. We work around your shutdown window. Learn more about our field deployable coating service.

Frequently asked questions
How long does a paper mill roll recoat take?
Workshop turnaround for a single roll is typically 5 to 10 business days from arrival. Field jobs are quoted to your shutdown window.
Can you recoat a roll that has been chrome plated underneath?
Yes, with the right primer. Send us the original spec or a sample area and we will confirm before the strip.
Do you offer emergency turnaround?
Yes for field service. Workshop emergency adds expediting fees that we quote case by case.
What coating systems work best on dryer cans?
PFA at 4 to 6 mil for most grades. We step to PTFE with conductive filler if static is an issue.
