Polyeuro 6881

Polyeuro^® 6881 is a relatively slow setting, 100% solids, flexible, two component spray polyurea that can be applied to suitably prepared concrete and metal surfaces.

Polyeuro 6881 – Polyurea Protective Coating for Broadcast Aggregate Applications

 Polyeuro 6881 is a two-component, flexible, 100% solids spray-applied polyurea designed primarily for use on horizontal surfaces requiring waterproofing and aggregate broadcast. It is ideal for environments that demand a seamless, chemically resistant, and elastomeric barrier, particularly on concrete and metal substrates.

 Polyeuro 6881 is typically applied as part of a system including:

·       Repair Material (if needed): PC-260 or Polyprime 21 mixed with sand for patching cracks, spalls, or voids.

·       Primer (when required): Specific primers depend on substrate—Polyprime 21 for concrete; contact Polycoat for stainless steel or aluminum primers.

·       Topcoat (optional for UV resistance): Aliphatic polyurethane or polyurea topcoat within 12 hours of application for color stability and UV protection.

 Suitable for a wide range of industrial and commercial settings, including:

·       Parking garage decks

·       Walkways and balconies

·       Warehouse floors

·       Mining operations

·       Food processing facilities

·       Landfill containment

·       Water and wastewater treatment systems

·       Mix Ratio: 1A:1B by volume

·       Application Temperature: 40°F to 120°F (4.4°C to 48.8°C)

·       Humidity Limit: <85% RH, and at least 5°F (3°C) above dew point during application

·       Tack Free Time: 8–15 minutes @ 75 mils

·       Recoat Window: 0–12 hours

·       Gel Time: 2–4 minutes @ 150°F (65.5°C), 50% RH

·       Spray Equipment: Heated, high-pressure plural-component systems (e.g., Graco “Hydra-Cat” 45:1)

·       Film Thickness: 20–100 mils per coat (wet)

·       Coverage: 1 gallon per 1600 ft² per mil thickness (i.e., at 100 mils = 16 ft²/gallon)

·       Not UV stable – must be topcoated with an aliphatic finish for UV resistance.

·       Highly elongatable (375%), with excellent tear strength (300 pli) and tensile strength (1900 psi).

·       Service temperature range is wide: -40°F to 250°F (-40°C to 121°C).

·       Zero VOC and odorless, meets USDA criteria, suitable for sensitive environments.

·       Not recommended for prolonged exposure to concentrated acids.

·       Shelf life: 1 year in unopened containers stored at 60–95°F (15–35°C).

·       Do not dilute. Homogeneous mixing of Side-B is critical.

·       Adhesion testing is advised on metal, plastic, and non-standard substrates before application.
