Polyeuro 5502

Polyeuro^® 5502 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. It has extremely fast gel time making it suitable for applications down to -20°F (-28.89°C).

Polyeuro 5502 – Two-component, 100% solids, aromatic polyurea protective coating.

 Polyeuro 5502 is used as a fast-setting, high-performance spray-applied elastomeric coating designed for waterproofing, abrasion resistance, and chemical protection. It is suitable for a wide range of industrial, marine, and infrastructure applications.

·       Base Coating: Polyeuro 5502 is self-contained and can be applied directly to many substrates without a primer, especially mild or carbon steel.

·       Primers (when needed):

o   For deteriorated concrete: PC-260 or Polyprime 21 with sand.

o   For metals and complex surfaces (aluminum, brass, copper, stainless steel, galvanized steel): appropriate primer post-surface preparation is recommended.

·       Topcoat (if UV resistance is required): Use an aliphatic polyurethane or polyurea coating within 6 hours for a colorfast, UV-stable finish.

 Polyeuro 5502 is recommended for:

·       Cold storage and food processing facilities

·       Manholes, walkways, and balconies

·       Parking decks and warehouse floors

·       Mining, refineries, and power plants

·       Secondary containment and marine environments

·       Structural steel and paper/pulp mills

·       Mix Ratio: 1:1 by volume

·       Pot Life: 4–8 seconds at 150–160°F

·       Tack Free Time: 45–60 seconds

·       Recoat Window: 0–6 hours

·       Application Temperature: Material preconditioning to 75–80°F; substrate at least 5°F above dew point

·       Spray Equipment: Heated plural component system (min. 2000 psi, >150°F at spray tip)

·       Minimum Applied Thickness: 1 mm

·       Coverage: 1 gallon per 1600 sq.ft. at 1 mil; adjust accordingly based on thickness (e.g., 80 mils = 20 sq.ft./gal)

·       Foot Traffic Ready: 1–4 hours

·       Full Cure Time: >24 hours

·       Substrates: Suitable for concrete, steel, wood, aluminum, fiberglass, some plastics, and more with appropriate preparation

·       Environmental Limits: Application down to -20°F possible; dry service range from -40°F to 250°F

·       Humidity: Application surface must be dry; minimum 5°F above dew point

·       UV Stability: Not UV stable — tends to yellow and lose gloss under UV exposure; topcoat recommended for outdoor exposure
