Food-grade release coatings for food processing equipment
Who can put an FDA-compliant release coating on food processing rolls and equipment? AEGIS Advanced can. We coat rolls, pans, panels, hoppers and other food-contact parts with release coatings built on a hard tungsten carbide base. Product lets go, cleans take less time, and the surface holds up to scraping and washdown. Food-grade roll coatings like these can cut regular and allergen line cleans by around 20%.
Why it pays back
- Shorter line cleans and allergen changeovers, so more run time
- Product and residue release instead of baking on
- Can be cleaned by hand, without aggressive scraping
- Hard, wear-resistant and doctorable, so it lasts and needs recoating less often
- Better resistance to permeation and corrosion than a soft coating alone
- Less damage to equipment from product buildup
Two food-grade options
| XR topcoat | X650 (PTFE topcoat) | |
|---|---|---|
| Release coat | XR extreme release | PTFE (TEFLON®) |
| Base | Tungsten carbide, about 80% of the surface | Tungsten carbide, about 80% of the surface |
| Hardness | About 600 HV | About 600 HV |
| Surface roughness | 5–7 µm Ra | 5–7 µm Ra |
| Cure | Room temperature | 350°F |
| Max operating temperature | About 400°F | About 700°F |
| Food contact | Met 21 CFR 177.2600 extractables testing (SGS Polymer Solutions, 2018) | Food-grade PTFE release coat; ask us for compliance documents for your application |
Not sure which? XR gives the best release against sticky, gummy product. X650 is the pick when the part runs hot.
What we coat
Conveyor and process rolls, forming and sheeting rolls, baking and cooling pans, hoppers and chutes, perforated panels and screens, pump housings and fittings. Any size part, coated in our Elkton, Maryland facility. Typical lead time is 2–4 weeks depending on volume. We’re ISO 9001.
Prefer a sleeve?
For rolls you’d rather cover than coat, our sister company Fluoron makes food-grade FEP heat shrink roller covers that install in the plant with a heat gun.
Common questions
Is the coating FDA approved?
The FDA doesn’t approve coatings. It sets the rules they must meet. Our XR release topcoat met the 21 CFR 177.2600 extractables limits for food-contact articles in SGS testing. Tell us your product and conditions and we’ll send the documents that apply.
Will it survive washdown and sanitizers?
Yes. The carbide base and release coat stand up to routine washdown. Tell us your chemicals and temperatures and we’ll confirm the right option.
How fast can you turn parts?
Typically 2–4 weeks depending on volume.
