Long-Lasting AASHTO M249 Thermoplastic Paint with Glass Beads and Pigments for Bright and Durable Markings

Product Description

Thermoplastic paint is a highly durable and reflective road marking material widely used for traffic management due to its exceptional visibility, weather resistance, and long-lasting performance. Composed of thermoplastic resins, pigments, glass beads, and fillers, it is applied in a molten state and solidifies quickly upon cooling, forming a robust adhesive layer on road surfaces.

- Composition Ingredients

- Synthetic Resin: It is the main component of thermoplastic road marking paint, such as rosin and its derivative modified resins, petroleum resins, polyester resins, etc. It has adhesive properties and quick-drying characteristics, enabling the paint to adhere to the road surface and bond through hot melting.
- Glass Beads: Usually with a diameter of 0.1-1.4 millimeters, they are colorless and transparent. They can improve the recognizability of the markings at night, enhance brightness and durability, and also protect the markings from wear.
- Pigments: Mainly white and yellow, such as titanium dioxide, zinc oxide, heat-resistant chrome yellow, organic yellow pigments, iron oxide, etc., which play a role in coloring and covering.
- Fillers: Such as calcium carbonate, sand, etc., which can ensure the mechanical strength, wear resistance, and color of the paint. The particle size of the fillers will affect the fluidity, sedimentation degree, and surface finishing of the paint.
- Additives: They can increase the plasticity of the coating, making it resistant to sedimentation, pollution, and fading.

Key Features of Thermoplastic Paint

1. Thermoplastic Property:
   The defining characteristic of thermoplastic paint is its ability to melt at high temperatures. When heated (typically between 180°C and 200°C or 356°F to 392°F), the solid paint transforms into a liquid state, making it easier to apply. Once it cools and hardens, it forms a durable, wear-resistant surface.

2. Durability:
   Thermoplastic paint is known for its long-lasting performance. It is highly resistant to wear and tear from traffic, weather conditions, and UV exposure, making it an excellent choice for high-traffic areas. The paint maintains its effectiveness even under harsh conditions like heavy rainfall, extreme temperatures, and constant vehicular traffic.

3. Reflectivity:
   One of the significant advantages of thermoplastic road markings is their reflective properties. Glass beads are often embedded in the paint during or immediately after application. These beads enhance the visibility of the road markings at night or in low-light conditions by reflecting headlights, improving safety for drivers and pedestrians.

4. Quick Drying:
   After application, thermoplastic paint cools and solidifies relatively quickly—usually within minutes. This quick drying time allows roads to be opened to traffic soon after application, minimizing disruption.

5. Eco-Friendly:
   Thermoplastic paints are often more environmentally friendly than traditional solvent-based paints. They typically contain fewer volatile organic compounds (VOCs), reducing their environmental impact. Additionally, they have a longer lifespan, meaning less frequent reapplication and reduced waste.
