FASTRACK™ HD-21A

• High durability and toughness.
• Excellent adhesion over various road surfaces.
• Rapid drying.
• Excellent retention of glass beads.
• Offers low annualized cost versus epoxy and thermoplastic systems.

A wet film thickness of ~ 750 μm (~ 500 μm dry) is suggested for best durability, while thinner lines, e.g., ~500 μm wet, will offer accelerated drying. For thicker films, large particle size glass beads are suggested for optimum retroreflectance and wet night visibility. A bead drop rate of approximately 0.8 kg/lt of paint (0.6 kg/m²) for a 10cm line and ~ 750 μm film thickness is a suitable initial range which can be fine-tuned for performance. The dry-to-no- pickup time is approximately 2–5 minutes for a single line application, depending on conditions. Traffic paints based on FASTRACK™ HD-21A Emulsion offer application with airless or conventional spray equipment to asphalt, concrete, or existing road markings that are adhering well to the pavement surface. Air and surface temperature should be above 10°C, and at least 3°C above the dew point during application. Paints will require longer drying times when the relative humidity exceeds 90%.

Dispose in accordance with all, local or national regulations. Empty containers may contain hazardous residues. This material and its container must be disposed in a safe and legal manner.

Store products in tightly closed original containers at temperatures recommended on the product label.

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 solvent- borne 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.
