Hot Melt Manufacturers AASHTO Reflective Highway Thermoplastic Road Mark Paint 30%Pre-Mixed Glass Beads Road Marking Paints
Product Description
Hot melt paint is a type of road marking material that becomes soft and moldable when heated and solidifies upon cooling. It is widely used for creating durable, reflective road markings, such as lines, symbols, and signs on highways and streets.
Key Characteristics:
-
Composition:
- Binders: Typically resins that provide adhesion.
- Pigments: For color, commonly white (titanium dioxide) or yellow (lead-free alternatives).
- Glass Beads: Added for retroreflectivity, enhancing night-time visibility.
- Fillers: Such as calcium carbonate, for bulk and stability.
-
Application:
- The paint is heated to 180-200°C (356-392°F) during application to achieve a liquid state.
- It is applied using specialized equipment in layers that cool quickly, forming a solid, durable marking.
-
Advantages:
- Highly durable, with a lifespan of 3-5 years depending on traffic and environmental conditions.
- Reflective properties due to embedded glass beads.
- Resistant to wear, UV light, and adverse weather conditions.
-
Common Uses:
- Road lines (centerlines, edge lines).
- Pedestrian crossings and parking lot markings.
- Symbols and arrows on road surfaces.
Thermoplastic paint is valued for its long-term performance and visibility, making it a preferred choice for high-traffic areas.
Detailed Process of Hot Melt Paint Construction
1. Road Cleaning
Before operation, the nearby area must be cleaned to ensure that there are no impurities such as oil, water, fallen leaves, weeds, ect., so as not to affect the adhesion effect, flatness and reflection effect of the line.
2. Set the Point and Mark Line
In the process of sampling, the calculation and measurement must be carried out in strict accordance with the construction drawings. Measure the several lanes that need to be drawn on the road, set the point, and then mark it with a stone pen. Use titanium dioxide powder to glue the rope for the elastic line. After the rope is removed, it will be corrected and improved to ensure that the line shape is clear and accurate.
3. Apply the Primer
The lower coating is a common binder in hot melt marking construction. It is applied to the highway road surface, which can make the hot melt coating better adhere to the road surface.
4. Spray the Paint
Before construction, first check the relevant coating equipment. Then heat the paint.
When the trolley moves forward, the paint will form a coating film on the road, and a layer of glass beads should be sprinkled on the coating film during the coating process.
When the trolley moves forward, take the reference line as the ruler, control the thickness and width of the line, and ensure the coordination, clarity and smoothness of the line connection between the straight line and the curve.
Note: During the coating process, in order to avoid the sedimentation and separation of the paint, it is necessary to stir the paint frequently.
5. Check and Correct
After the coating is completed, check and correct the line shape, check the spread of glass beads, etc.
After confirming that it is correct, the construction site will be cleaned up.
After the line is dried and hardened, the relevant construction equipment can be transferred, the safety facilities can be dismantled, and the traffic can be opened.

Application Methods
-
Hot Application (Extrusion or Screeding):
- The paint is melted and applied directly to the surface using a screeding machine.
- The liquid paint is applied in a controlled layer, creating even thickness.
- This method is commonly used for highway and large-scale projects, as it offers quick application and excellent bonding.
-
Spray Application:
- The paint is melted and sprayed using specialized equipment, providing a smooth and even finish.
- Ideal for more detailed applications, such as symbols, logos, or intricate markings.
-
Preformed Thermoplastic Sheets:
- Pre-cut thermoplastic sheets can be applied to road surfaces, especially for high-traffic areas or to make highly visible markings (like pedestrian crossings).
- These sheets are heated and bonded to the surface, providing durable markings.
-
Machine Extrusion:
Application of Thermoplastic Paint
- Fast Drying Time: Reduces traffic disruption and increases operational efficiency.
- Durability: Creates strong, long-lasting markings resistant to wear and tear.
- Visibility: High retroreflectivity, improving nighttime safety.
- Cost-Effective: Lower long-term maintenance costs due to the extended lifespan of the markings.
