High Reflectivity Thermoplastic Paint for Roadway Marking Coating for Improved Road Visibility

1. Surface Preparation

• Ensure the road surface is clean, dry, and free of dust, dirt, grease, or moisture for proper adhesion.
• For old roads, remove any loose paint or debris.
• If necessary, apply a primer to improve adhesion, especially on concrete surfaces.

2. Heating the Thermoplastic Paint

• Use a preheater or thermoplastic melting kettle to heat the paint to around 180-200°C (356-392°F).
• Stir continuously to maintain an even consistency and prevent burning.

3. Application of the Paint

• Hand or Machine Application:
  • Screed, Extrusion, or Spray Machine – For large road markings, use a specialized road marking machine.
  • Hand-Pushed Applicator – Suitable for smaller projects or touch-ups.
• Apply the molten thermoplastic evenly on the road surface at a thickness of 1.5 to 3 mm.

4. Adding Glass Beads

• While the paint is still hot, sprinkle glass beads on top to enhance reflectivity.
• Some thermoplastic paints contain pre-mixed glass beads, but additional beads may still be applied manually or automatically.

5. Cooling and Curing

• The marking cools and hardens within 2-5 minutes, forming a durable and traffic-resistant layer.
• Allow sufficient time for full curing before opening to traffic.

6. Quality Check

• Inspect for proper thickness, adhesion, and reflectivity.
• Remove excess material and touch up any defects.
