FASTRACK™ 3427

FASTRACK™ 3427 Polymer Emulsion is a second generation all-acrylic emulsion for fast-dry waterborne traffic marking paints with improved durability. Traffic marking paints based on FASTRACK™ 3427 Polymer Emulsion feature fast dry over a broad range of application conditions and excellent durability in terms of retention of glass beads for night visibility and wear properties over asphalt, concrete and old markings.

Applications & Uses

Coating End Applications
Product Applications
  • FASTRACK™ 3427 Polymer Emulsion can be applied with airless or conventional air-spray equipment to asphalt, concrete, or existing roadmarkings that are adhering well to the pavement surface.
  • Air and surface temperature should be above 50°F and at least 5°F above the dew point during application.
  • Paints will require longer drying times when the relative humidity exceeds 80% with minimal air flow.

Technical Details & Test Data

Technical Data
  • Performance Advantages:
    • Conventional waterborne films that exhibit enough surface dry to prevent the paint from being “picked-up” and tracked onto the road by traffic, may not be dry under the surface film.
    • Waterborne traffic paints need to reach a surface dry and "dry-through" stage before they begin to withstand an early rain shower.
  • Drying Performance:
    •  FASTRACK™ 3427 Polymer Emulsion and its predecessor FASTRACK™ 2706, will dry faster to "no pick-up" and "drythrough" than conventional waterborne polymers.
    • The faster dry is particularly evident when the drying conditions are poor (high humidities, and low air flow and temperatures).
    • Furthermore, fast "dry-through" characteristics of waterborne traffic markings based on FASTRACK™ 3427 Polymer Emulsion will make them much more resistant to damage from an early rain shower than those based on conventional waterborne polymers.
  • Dry-to-no Pick-up Time:
    •  A white paint based on FASTRACK™ 3427 Polymer Emulsion was compared to a commercial solventborne traffic paint on the road for Auto-No-Track Time as specified in ASTM Method D-713.
    • The paints were applied to a 15 mil wet thickness and glass beads were dropped onto the paint at a rate of 6 lbs. per gallon for a 4-in. wide line (275 grams/sq.m. of paint).
    • The humidity was high (84% relative humidity) and there was only a slight breeze (2 - 4 mph).
    • After only 35 seconds, a car passing over the waterborne marking based on FASTRACK™ 3427 Polymer Emulsion did not track paint on the road. Tracking was evident after 45 seconds with the fast-dry solventborne paint.

  • Durability:
    • The service life of traffic markings also depends on the marking having good wear properties.
    • In road tests using transverse test lines to accelerate wear, waterborne markings based on FASTRACK™ 3427 Polymer Emulsion have shown excellent durability over both asphalt and concrete road surfaces in a variety of climates. FASTRACK™ 3427 Polymer Emulsion has improved wear characteristics compared to FASTRACK™ 2706. 
  • Glass Bead Retention:
    • The visibility of traffic markings at night requires retention of the glass beads applied to that marking.
    • Night visibility can be monitored with a retroreflectometer that measures the low angle reflectance of light off the beaded marking.
    • The following data compare the loss of retroreflectivity of white waterborne traffic markings based on FASTRACK™ 3427 Polymer Emulsion with commercial solventborne markings based on alkyd resins (with and without chlorinated resin modification).
    • Note that the waterborne fast-dry markings based on FASTRACK™ 3427 Polymer Emulsion retain their retroreflectance (hold onto reflective glass beads) considerably longer than the commercial solventborne traffic markings. 
    • FASTRACK™ 3427 Polymer Emulsion also shows improved bead retention over its predecessor, FASTRACK™ 2706.

Storage & Handling

Handling Information
  • Clean-up is accomplished with clean or soapy water to remove wet paint from equipment.
  • Stainless steel equipment should be used, and typical paint solvents can assist if removal of dried paint from tools and equipment is necessary.
  • All solvents and solventborne paint should be removed from tanks and spray equipment prior to handling waterborne paints to avoid contamination, and equipment should be cleaned after each use.
  • An ammonia solution can be floated on the surface of stored paint to prevent skinning.
