X550 field-cured PTFE coating for dryer cans
Can a dryer get a PTFE release coating without coming out of the machine? Yes, with AEGIS Advanced X550. We spray X550 onto the dryer while it turns slowly, then the mill turns the steam on and the dryer’s own heat cures the coating. It needs at least 250°F to harden. You get PTFE release, continuous service to 550°F, and a surface that stands up to pike poles.

Why X550
- Applied and cured on the machine, so the dryer stays in place
- Field applied in less time than installing an FEP dryer cover
- Less expensive than an FEP cover, with better heat transfer
- Withstands pike pole damage
- Continuous service at 550°F (288°C)
- An alternative to doctoring; starch and coating don’t build up
Starch spray nozzles
X550 also keeps starch from building up on spray nozzles in the press section. When buildup on a nozzle lets go, it can mark the sheet or cause a break.
X550 or a sleeve?
X550 is a coating, so it’s thinner than a sleeve and moves heat better. An FEP dryer cover from our sister company Fluoron gives the best release and is installed on the machine as well. If your dryer is doctored or sees heavy abrasion, look at XR100T instead.
Common questions
What temperature does the dryer need to reach?
At least 250°F (121°C) to harden the coating. Most dryers get there on their own steam.
How long does it take?
Less time than an FEP dryer cover install. We plan it around your shutdown.
