White Yellow Reflective Pavement Thermoplastic Road Marking Coating Spray Application Thermoplastic Road Paint

Product Description

Thermoplastic Road Marking Paint is a durable, heat-activated paint applied to road surfaces to create clear, long-lasting traffic markings, such as lane lines, pedestrian crossings, symbols, and road signs. It is composed of a blend of resins, pigments, fillers, and glass beads, designed to ensure excellent visibility and resistance to wear and environmental conditions. Here's a more detailed description of its components, properties, and application:

Components:

1. Resins: These are the base material that gives the paint its structure. Common resins include alkyd, acrylic, and thermoplastic resins, which are chosen for their ability to bond strongly to road surfaces and form a hard, durable layer once cooled.

2. Pigments: These provide color to the road markings. White and yellow are the most common pigments, though other colors can also be used depending on the marking requirements.

3. Fillers: These are inert materials used to bulk up the paint and help with the application. They often include limestone, calcium carbonate, or other fine powders.

4. Glass Beads: Tiny glass beads are embedded into the surface of the thermoplastic marking. These beads enhance the retroreflectivity of the paint, meaning they reflect light back towards the source (e.g., headlights from vehicles) for improved visibility at night or in low-light conditions.

Key Features:

1. Heat-Activated: Thermoplastic paint is applied in a molten form, typically heated to a temperature between 375°F to 400°F (190°C to 204°C). It is spread onto the road surface and immediately hardens upon cooling, forming a solid, durable coating.

2. Durability: Once applied, thermoplastic paint creates highly resistant markings that can withstand wear from traffic, environmental factors like rain and sunlight, and abrasion from tires. It is particularly effective in areas with heavy traffic.

3. Fast Drying Time: Since it hardens quickly upon cooling, thermoplastic paint allows roads to be reopened to traffic sooner compared to other types of road marking paints. This is a key benefit for high-traffic areas or where lane closures need to be minimized.

4. Retroreflectivity: The glass beads embedded in the paint provide a reflective surface that improves visibility, particularly in low-light conditions such as nighttime driving or during poor weather. This enhances safety by making road markings more visible to drivers.

5. Weather Resistance: Thermoplastic markings are resistant to UV rays, rain, snow, and chemicals like oil and fuel, which means they maintain their color and visibility for longer than many other types of markings.

6. Thickness and Customization: Thermoplastic paint is often applied in varying thicknesses, depending on the traffic volume and marking requirements. Special formulations, such as thick-film thermoplastic paint, are available for areas with very heavy traffic or extreme wear.

7. Environmental Resistance: It can handle high temperatures and harsh weather conditions. Unlike other paints, thermoplastic markings do not fade or peel easily under UV exposure.

Detailed Process of Thermoplastic Marking 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.

Advantages of Thermoplastic Road Paint

The advantages of hot melt marking paint are as follows:
 

Strong adhesion and durability

- It has strong adhesion to the road surface, ensuring that the marking lines remain intact, clear, and not easily peeled off under the long-term influence of vehicle rolling and various environmental factors.
- It has excellent wear resistance and a long service life, reducing the waste of manpower and material resources caused by repeated constructions and the obstruction to normal traffic.

Good visibility

- Reflective glass beads can be mixed during construction, so the marking lines have good reflective performance at night, which can greatly improve the safety and efficiency of driving at night and make it easier for drivers to see the road markings clearly under low-light conditions.
- The color of the paint itself is bright and eye-catching, providing clear guidance for drivers and pedestrians even during the day.

Rapid drying and convenient construction

- It dries quickly and can be opened to traffic shortly after construction, effectively reducing the impact on traffic and improving construction efficiency.
- The construction method is relatively simple. Usually, a special marking device is used to scrape or spray the melted paint on the road surface, which is easy to operate and can form neat and uniform marking lines.

Economy

- Although its initial purchase cost may be relatively high, due to its long service life, it has good cost-effectiveness in the long run and can reduce the maintenance and re-marking costs of road markings.

Environmental adaptability and maintainability

- It has good weather resistance and water resistance, can adapt to various harsh natural environments, maintain vividness for a long time, and is not easy to fade or be damaged due to natural aging, rain washing, and other factors.
- The later maintenance is relatively easy. If the marking lines need to be modified or removed, the paint can be softened by heating and then processed.
