Road line paint Yellow white color traffic coating powder Thermoplastic Hot Melt road marking paint

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:

1. 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.

2. 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.

3. 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.

4. 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 of Thermoplastic Paint

1. Road and Highway Markings:

Lane Markings: Solid lines, dashed lines, and lane dividers to direct traffic flow and indicate lanes.

Edge Lines: To define the boundaries of the road.

Center Lines: To separate lanes of traffic moving in opposite directions.

Chevron and Diagonal Markings: To guide drivers through curves, intersections, and dangerous areas.

Pedestrian Crossings: High-visibility markings for pedestrian areas on roads, ensuring safety for pedestrians.

Bus Lanes & Special Traffic Lanes: Dedicated lanes for public transportation or special vehicles, clearly marked for easy identification.

2. Urban Roads and Streets:

Stop Lines & Give Way Lines: Markings to define stopping positions at intersections.

Parking Lot Markings: Used in commercial, residential, and public parking areas to delineate parking spaces.

Bicycle Lanes: Clearly defined lanes for cyclists to ensure their safety on the roads.

Pedestrian Crosswalks: Highly reflective lines to ensure pedestrian safety and visibility.

Traffic Symbols: Arrow markings, road signs, and special symbols for directional guidance.

3. Airport Runways and Taxiways:

Runway Markings: For both day and night visibility to guide aircraft safely during landing and takeoff.

Taxiway Markings: Indicate the safe paths for aircraft movement on the ground.

Threshold and Centerline Markings: Provide guidance for pilots during approach and takeoff.

4. Safety and Hazard Markings:

Warning Markings: Used to highlight areas of potential danger, such as sharp turns, construction zones, or pedestrian crossings.

Hazard Markings: For locations such as narrow roads, sharp curves, or hazardous construction zones.

Road Reflectors: Often applied with hot melt paint to improve night-time visibility and reflectivity.

5. Signage and Symbols:

Directional Arrows: To direct traffic in a specific direction.

Symbols: Used for specific traffic instructions, such as "no parking," pedestrian symbols, or vehicle restrictions.

Road Signs: Temporary or permanent markings indicating regulations like speed limits, lane closures, etc.

6. Sports Fields and Recreational Areas:

Track & Field Markings: Hot melt paint can be used for marking lanes on tracks or fields used for sports like soccer, football, or basketball.

Playground Markings: To designate play areas, boundaries, or game-specific lines.

7. Special Applications:

Industrial Markings: Used in factory environments for floor markings, aisle markings, and safety demarcation.

Railway Tracks and Stations: Applied for demarcating safe zones, pathways, and directional indicators for trains and pedestrians.

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:

Involves using an extrusion machine to lay down a layer of melted thermoplastic directly on the road surface, creating a thick, durable marking.

This method ensures uniformity in thickness and ensures proper adhesion to the surface.
