Polyeuro^® 5502 FG (Food Grade) is a fast setting, rapid curing, 100% solids, flexible, aromatic, two component spray polyurea that can be applied to suitably prepared concrete and metal surfaces. Polyeuro 5502 FG has an extremely fast gel time which makes it suitable for most polyurea installations.

Polyeuro 5502 FG – Food Grade Two-Component Aromatic Polyurea Protective Coating

 Polyeuro 5502 FG is a 100% solids, fast-setting, aromatic polyurea coating designed for protective applications on concrete and metal substrates. It is certified for dry solid food contact up to 104°F (NSF 51) and suited for both industrial and food processing environments. This coating provides a flexible, seamless barrier with high durability and excellent chemical resistance.
