Description
HOTLINE® Fast Dry Waterborne Traffic Marking Paint is a fast drying waterborne traffic paints made with some of the most advanced resin technology on the market today. These products conform to the current VOC regulations.
Material Use:
Hotline® Waterborne Traffic Paints TM2320 and TM2321 are high-performance, fast-drying, low-VOC coatings designed for traffic marking applications. These paints are primarily used for long-line striping on streets and highways, as well as for parking lot striping. They are also suitable for auxiliary markings such as stop bars, crosswalks, and airfield striping.
System Components:
This system consists of a single-component waterborne acrylic traffic paint available in two color variants: TM2320 (Bright White) and TM2321 (Lead-Free Yellow). The system is designed to be used with glass beads (6 lbs. per gallon) for enhanced reflectivity and visibility. No primer or base coat is required for standard applications, and the paint is applied directly to the prepared surface.
Applications:
Hotline® Waterborne Traffic Paints are intended for use with long-line striping trucks and walk-behind striping equipment. They are suitable for application on asphalt and concrete surfaces, provided the substrate is clean, dry, and free of contaminants. These paints are not recommended for pedestrian walkways, ramps, floors, or stairs due to the potential for slipperiness when wet.
Application Details:
- Application Equipment: Long-line striping trucks (with stainless steel components) or walk-behind stripers. Airless spray equipment is preferred; air-atomized equipment may also be used. Hand application with brush or roller is not recommended.
- Film Thickness: Recommended wet film thickness is 13–15 mils.
- Coverage Rate: Approximately 110–125 square feet per gallon at the recommended thickness.
- Glass Beads: Apply 6 lbs. of glass beads per gallon of paint for optimal reflectivity.
- Dry Time: No-track condition achieved in approximately 60 seconds at 15 ±1 mils wet film thickness with proper bead distribution. For parking lot applications without beads, dry time is typically 10–20 minutes.
- Pot Life: Not applicable – single-component, ready-to-use product.
- Curing Time: Full cure requires several hours at temperatures above 50°F.
- Application Temperature Range: Do not apply if air or surface temperature is below 50°F or if temperature is below the dew point.
- Humidity Limitations: High humidity (>75% RH) may extend dry time; relative humidity above 85% will significantly slow drying.
- Surface Preparation: Surface must be clean, dry, and free of loose or peeling paint. Moisture in the substrate or presence of sealers/efflorescence on new concrete may interfere with adhesion.
- Recoatability: Most previously painted lines can be repainted without additional preparation if the existing paint is well-adhered. Multiple layers may eventually require removal due to inter-coat adhesion issues.
- Thinning: Not typically required. If necessary, thin with clean water only, not exceeding 4 oz. per gallon. Thinning may extend dry time and promote settling.
- Cleanup: Clean wet paint with water. Dried paint requires solvent-based cleaners such as xylene. Avoid solvent contamination of unused paint.
Special Notes:
- Hotline® Waterborne Traffic Paints are not UV-stable coatings but are designed for outdoor use with good durability under normal traffic and weather conditions.
- These paints are not intended for use on pedestrian surfaces or large horizontal areas where slip resistance is critical.
- Store in a temperature-controlled environment (do not freeze or exceed 115°F). Do not invert or roll drums to preserve the anti-skinning design.
- These products are not regulated by the U.S. Department of Transportation (DOT).
- VOC content is less than 100 g/L, making them compliant with most environmental regulations.
This system is ideal for municipalities, contractors, and airfield maintenance teams seeking a fast-drying, durable, and environmentally friendly traffic marking solution.
