Food Processing & Cold Storage
A food plant floor gets washed down, walked on, driven on and thermally cycled, and whatever is on it has to be acceptable in a facility that makes food. Cold storage adds a second problem: coatings have to stay flexible and keep bonding at temperatures where many chemistries go brittle.
Polycoat Products manufactures spray polyurea linings and polyaspartic topcoats used in food-processing plants, cold-storage facilities and dry food storage, including grades that meet USDA criteria and a Food Grade polyurea.
System Selection
| Product | Type | Select it for |
|---|---|---|
| Polyeuro® 5502 FG | Aromatic spray polyurea | The Food Grade formulation. Dry food storage, dry food dispensers, silos and warehouse floors. Zero VOC, meets USDA criteria, odorless. |
| Polyeuro® 5502 | Aromatic spray polyurea | General food-processing and cold-storage lining. Zero VOC at 100% solids, meets USDA criteria, odorless, good chemical resistance. |
| Polyeuro® 5502-F | Aromatic spray polyurea | Seamless, odorless, zero VOC, with excellent thermal stability. |
| Polyeuro® 5602 | Aromatic spray polyurea | Low-permeance grade. Coats carbon or mild steel without primer on properly prepared surfaces. |
| Polyeuro® 7851 / 7901 | Aliphatic spray polyurea | Color stable. Where the finished surface is exposed to light and appearance matters. |
| Polycoat-Staingard™ 7000 | Aliphatic polyaspartic polyurea topcoat | USDA Approved for Incidental Food Contact. Applied at 8–12 mils (200–300 microns) in a single pass on horizontal surfaces. Abrasion resistant, with gloss and UV stability. |
| Polycoat-Staingard™ 9072SC | Aliphatic polyaspartic topcoat | Highly chemical resistant topcoat with superior chemical resistance, for cold storage and food processing areas. |
| Polyliner 700 | Phenol novolac resin lining | Extremely chemical resistant with a high heat deflection temperature. Heavy-duty chemical resistant protective lining for tanks and containment. |
| TuffShield® 801 | Spray elastomer | Superior abrasion and impact resistance where traffic is the governing load. Meets USDA criteria. |

Why Polyurea in a Wash-Down Plant
- Seamless — no joints for product or bacteria to sit in.
- Odorless and zero VOC grades, so areas can be returned to service quickly.
- Low temperature flexibility and excellent thermal stability for cold storage and thermal cycling.
- Meets USDA criteria across most of the Polyeuro® range, with Staingard™ 7000 USDA approved for incidental food contact.
Confirming Suitability
“Meets USDA criteria” and “USDA approved for incidental food contact” are different scopes. Confirm the applicable scope for your process, contact type and wash-down regime against the current technical data sheet, and speak to our technical service team before specifying.
