Thermoplastic Road Marking Paint For Road Surfaces With Quick Hardening Time And Strong Adhesion
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.
