Thermoplastic Road Marking Paint for Road Surfaces with Quick Hardening Time and Strong Adhesion


Product Description


Thermoplastic road marking paint, also known as hot melt marking paint, is a type of powder paint used for road surface markings. When heated to approximately 200°C (392°F), it melts and is applied to road surfaces, where it quickly hardens upon cooling to form a durable, wear-resistant, and reflective layer.


Composition:

The paint typically consists of:

  • Synthetic Resins: Provide thermoplasticity, enabling the paint to dry quickly and adhere strongly to the road surface.

  • Glass Beads: Enhance reflectivity, improving nighttime visibility.

  • Pigments: Offer color and opacity; common colors include white (using titanium dioxide) and yellow (using organic pigments).

  • Fillers: Such as calcium carbonate and sand, which contribute to the paint's mechanical strength and wear resistance.

Steps to Use Thermoplastic Road Marking Paint

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.
