5500 F Fast Set PolyUrea/Polyaspartic
5500 F Fast Set is a two-component, aliphatic polyurea/aspartic amine blend designed for:
- Clear or pigmented elastomeric finishes.
- High gloss, high build coatings with excellent elongation and impact resistance.
- Use as a durable topcoat in ASTC flooring systems.
- USDA compliance for incidental food contact.
- Available in different solid content ranges from 65%-100% solids upon customer request

Unique Characteristics
Ease of Use: Extended working time for efficient application.
Durability: High build with excellent stain, abrasion, and chemical resistance.
Customization: Tintable with ASTC pigment packs and available in low-odor versions.
Non-Skid Options: Incorporates ASTC’s “SSR” aggregate for added safety.
Advantages
UV stable and non-yellowing.
Resistant to plasticizer migration from tires.
Excellent adhesion to concrete and existing coatings.
Waterproof and elastomeric properties.
Quick turnaround for high-traffic areas.
Applications
5500 F Fast Set 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
Concrete Curing: Ensure a minimum 28-day cure.
Surface Cleaning: Remove all contaminants, such as oils, wax, and curing agents.
Profile Creation: Abrade the surface to create a rough profile (2-3 mils).
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
Mixing:
Combine parts A and B at a 1:1 ratio using a jiffy mixer.
Mix for 1-2 minutes without incorporating air.
Coating:
Apply using a notched squeegee and back-roll with a 1/4”-3/8” nap roller.
Maintain thin coats of 5-10 mils for optimal results.
Recoat Timing:
Recoat within 1-2 hours or after light sanding if exceeded.
