Unique Characteristics

• Extended Working Time: Suitable for environments where faster-set versions are impractical.
• Durability: High build provides added protection for flooring systems.
• Non-Skid Options: Incorporates ASTC’s “SSR” aggregate for safety and usability in various environments.
• Low Odor Versions: Available for use in sensitive applications.

Advantages

• UV stable and resistant to yellowing.
• High stain resistance to tire plasticizer migration.
• Excellent adhesion to concrete and topcoats.
• Waterproof and elastomeric properties for durable protection.
• Quick turnaround for floor applications.

Applications

The 5500 HH is suitable for:

• Decorative concrete floor finishes.
• Industrial, commercial, and residential floor coatings.
• Clear topcoats for color chips and quartz.
• Kitchen floors, slabs, stairs, and pedestrian walkways.
• Exterior applications requiring UV stability.

Preparation

1. Concrete Curing: Ensure a minimum 28-day cure.
2. Surface Cleaning: Remove contaminants, such as oils, wax, and curing agents.
3. Profile Creation: Abrade the surface to create a rough profile (2-3 mils, ASTM D4259).
4. Moisture Testing: Ensure moisture vapor transmission (MVT) does not exceed 3 lbs per 1,000 sq ft per 24 hours.

Priming

• Self-Priming: Can be applied directly to concrete.
• Optional Primers: Use ASTC’s 6000 Series Epoxy Primer, 70001 Pen Prime, or 8000 CMW for enhanced performance.

Application Guidelines

1. Mixing:
   • Combine components A and B at a 1:1 ratio using a jiffy mixer.
   • Mix for 1-2 minutes without incorporating air.
   • Add pigments if required, ensuring uniform dispersion.
2. Coating:
   • Apply with a notched squeegee and back-roll with a 1/4”-3/8” nap roller.
   • Maintain thin coats (5-10 mils) for optimal results.
3. Recoat Timing:
   • Recoat within 4-6 hours or after light sanding if exceeded.

General Physical Characteristics

Special Considerations

• Cold Conditions: For applications below 50°F, use 5500 F or EX for faster curing.
• Hot Conditions: Use HH or HHH versions for high-temperature, high-humidity environments.
• Chemical Resistance: Resists a wide range of chemicals, including acids, ethanol, and motor oil.

Limitations

• Avoid application on wet surfaces or in environments with high moisture vapor drive.
• Store kits in a cool, dry environment away from sunlight.
• For professional applicators only. Refer to the MSDS before use.
