Thermoplastic Road Paint Wear Resistant High Reflective Road Marking Use
Factory Price Thermoplastic Road Paint Wear Resistant High Reflective Road Marking Use
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 of Hot Melt Marking Paint:
-
Synthetic Resins: These serve as binders, providing thermoplasticity and ensuring strong adhesion to the road surface. Common resins used include:
- Aliphatic Hydrocarbon Resins: Derived from petroleum, these resins offer excellent color stability and resistance to UV degradation.
- C5 Petroleum Resins: These are widely used due to their good compatibility with other ingredients and their ability to enhance the paint's adhesive properties.
-
Pigments: Provide color and opacity to the markings.
- Titanium Dioxide (TiO₂): Used for white markings, it offers high brightness and opacity.
- Organic Pigments: Such as Pigment Yellow 65, 74, or 83, are used for yellow markings.
-
Glass Beads: Incorporated to enhance reflectivity, improving nighttime visibility. These beads are typically colorless and transparent, reflecting light from vehicle headlights back toward the driver.
-
Fillers: Materials like calcium carbonate and silica sand are added to improve mechanical strength, wear resistance, and to adjust the paint's viscosity.
-
Additives: Substances such as plasticizers, anti-settling agents, and stabilizers are included to enhance flexibility, prevent sedimentation, and improve overall durability of the paint.

Advantages:
-
Durability: Thermoplastic markings are engineered to withstand heavy traffic, extreme weather, and UV radiation, ensuring long-lasting visibility and reducing maintenance needs.
-
Reflectivity: The inclusion of glass beads provides high reflectivity, enhancing road safety by improving visibility during nighttime or low-light conditions.
-
Quick Drying: The paint cools and hardens rapidly after application, minimizing traffic disruptions
How To Apply The Thermoplastic Road Marking Paint
-
Surface Preparation:
- Ensure the road surface is clean, dry, and free from debris, oil, or existing markings. Proper adhesion requires a well-prepared surface.
-
Measuring and Marking:
- Use chalk or temporary paint to outline the areas where the thermoplastic paint will be applied. Double-check measurements to ensure compliance with local regulations.

-
Safety Precautions:
- Set up warning signs, cones, and barriers to divert traffic and ensure worker safety during the application process.

-
Heating the Thermoplastic Material:
- Heat the thermoplastic paint to approximately 200°C (392°F) using specialized equipment, such as a thermoplastic preheater, to achieve a molten state suitable for application.

-
Application Methods:
- Screed Box Application: A screed box applies the molten thermoplastic material onto the road surface, creating uniform lines.
- Extrusion: The material is extruded through a die to form markings with specific dimensions.
- Spraying: High-pressure airless spraying equipment distributes the molten material evenly across the surface.
- Screed Box Application: A screed box applies the molten thermoplastic material onto the road surface, creating uniform lines.
-
Glass Bead Dispersion:
- Immediately after application, while the thermoplastic is still hot, glass beads are dispersed onto the surface to enhance nighttime visibility by reflecting headlights back toward drivers.

-
Cooling and Hardening:
- The applied material cools and hardens rapidly, typically within a few minutes, allowing for minimal traffic disruption.
