5500 EX is a 90% solid, two component, Aliphatic multifunctional polyurea aspartic amine blend specifically designed as a pure polyurea slow system roll-down. The EX is the designation for the 5500 Extended Cure providing additional working time compared to the 5500 Fast Set product. The polymer structure is very clear and may be pigmented, is non-yellowing, very tough, excellent color retention, good chemical resistance with excellent adhesive properties. 5500 EX is a reactive two component system highly resistant to staining and marking.
The 5500 EX "roll-down" polyurea is used as a clear finish coat with good elongation and flexibility. The 5500 EX aliphatic product conforms to the requirements of the USDA for incidental food contact and is formulated to be non-color changing, abrasive resistant, non-brittle, flexible, quick set with impact resistance.

Concrete must have a minimum 28 day cure prior to application. Remove any curing agent, form release materials, oils, wax, moisture or any material that may affect bonding. Clean and wash to remove contaminants and maintain pH 8.0-11.0. **Provide rough profile minimum 2 mils. Use ASTM D4259 Abrading Concrete and ASTM F1869 Measuring Moisture Vapor Emission. Seal/repair all bug-holes, cracks and spalls, see ASTC data sheets on 830, 4034.
Note: High Tensile, hard concrete with small aggregate is difficult to grind. It is important to observe the result (appearance) of grinding this type of concrete. It may be necessary to grind this type of concrete with a rougher dry diamond blade to assure a good 2 to 3 mil profile. When coating this type of concrete with the 5500 and added pigment, add additional Xylene to the mixed 5500/pigment. It is suggested that about 3 to 4 ounces of Xylene be added to the mix for a gallon (only for high tensile concrete). Check the penetration of the 5500/pigment to assure that the product is getting a “bite’ to the hardened or high tensile type of concrete.
5500 is self-priming.
Moisture Vapor Reduction:
Use ASTC’s CMW to reduce moisture vapor drive. Efflorescence or white powder-like material visible on the concrete slab indicates moisture vapor drive. See CMW data for efflorescence treatment.
Use a jiffy mixer and 650 rpm drill motor to mix product. Mix at slow speed adding part B into part A *while mixing. Do not change the proportions. Mix completely for approximately one to two minutes. Avoid mixing air into the blend. Mix at 1:1 ratio in a separate clean pail, pour out on surface, squeegee and back- roll. Fast set product:
Do not let the mixed product remain in the mixing container. Stick/hand mixing not recommended.
Use 12 ounces to 14 ounces for the pigment provided by ASTC. Example; ½ gallon A and ½ gallon B = one mixed gallon – add 12-14 ounces per mixed gallon of product. If using White add approximately 16 ounces per mixed gallon.
Do not use other pigments as they are not formulated with the proper base materials that are compatible with the 5500.
Do not overload the 5500 with pigment, use the minimum amount of pigment for the desired effect.
Important: When adding pigment to the mix of 5500 as a base coat is it helpful to add about 3-4 ounces of Xylene per mixed gallon of product and pigment mix. The addition of the solvent helps with dispersion of the pigment and with penetration into the substrate. No other solvent is needed.
Tan, Wheat/Straw, Fog Gray, Pearl Gray, Medium Gray, and Black. White is also available for adding to the above colors as desired.
Application range; 45°F to 90°F. Apply the product using a notched squeegee or similar squeegee to move the product over the application area. *Hot surfaces may accelerate gel time of the product. *High Humidity will accelerate the gel time of the product. Product should be back-rolled using a short nap roller, about ¼” to 3/8”.
Apply in thin films from 5, 8 or 10 mils per coat. Do not apply thicker than 12-15 mils at one time.
Recoat Window; Apply a second coat as soon as the first coat can be walked on, 45 minutes to 1.5 hours.
If the recoat window is exceeded, abrade using 60 to 80 grit sand paper or equal. If the recoat window has been exceeded by more than 3 hours, abrade using a #36 grit heavy paper.
If recoat window is exceeded, sand lightly to produce a profile, wipe with acetone and re-coat. *Environmental conditions as high humidity may require a light mist spray during final rolling, contact ASTC for details.
Approximately 45/50 minutes to 1/1.5 hours for low foot traffic volume, 1.5 to 2.5 hours for increased foot traffic volume and 4 to 8 hours for mechanical wheeled traffic. Test surface cure to be sure surface is ready for vehicles before allowing access. Cure is affected by high humidity. Humidity effects cure, for high humidity conditions use 5500 HH, long working time (HH is High Humidity and High Heat).
When environmental conditions are cool or cold and the ambient temperature is about 50 degrees F, the 5500 EX cure will slow down. Although the polyurea product does slow, it will continue to cure but will take longer to develop it’s hardness. For applications in reduced temperatures starting at around 50F use the 5500 Fast Set. The 5500 Fast Set cure will not slow down as much as the 5500 EX product and the Fast Set will develop physical properties, hardness, etc. sooner than the EX will in cold conditions.
Note: The product is resistant to most tires, however, there are some tires that may stain the coating. Not all tires and their characteristics can be tested for staining. If moisture vapor drive is evident or efflorescence is visible use a vapor barrier CMW. Use compatible surface repair products with 5500. Pot life is effected by environmental temperatures and humidity.
Do not use on wet surfaces or expose part A to moisture. Keep out of direct sunlight and store the product kits on wood pallets at room temperature. Use a Nitrogen blanket over unused product for proper storage and protection from humidity.
