FASTRACK™ HD-21A

FASTRACK™ HD-21A Emulsion is an acrylic emulsion binder for high-durability traffic markings. Using a patented crosslinking technology, FASTRACK™ HD-21A Emulsion combines exceptional durability with the ease of handling and application typically associated with water-based technology. Designed to be a true waterborne durable traffic paint, FASTRACK™ HD-21A Emulsion is an excellent choice for situations where existing waterborne paint equipment is available, and where the additional benefits of rapid drying and excellent glass bead retention are critical. The ease of cleanup, enhanced worker safety, and reduced disposal costs are inherent features of FASTRACK™ HD-21A Emulsion that can translate into additional value and convenience for pavement marking applicators.

Applications & Uses

Coating End Applications
Product Applications

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%.

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 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.

Storage Conditions

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