Hot Melt Road Marking Paint with Synthetic Resins for Strong Adhesion and Wear Resistance

                                  Product Description                                       

Hot melt paint is a type of thermoplastic coating that is applied in a molten or liquid state, usually at elevated temperatures, and solidifies as it cools. This type of paint is primarily used for applications such as road markings, traffic lines, and industrial coatings. Hot melt paint is formulated to be durable, weather-resistant, and provide long-lasting performance in high-traffic and outdoor environments.

1. Composition

• Resins: The primary binder that holds the paint together and adheres to the road surface. Typically, synthetic resins are used to provide good adhesion and resistance to wear.

• Pigments: Commonly titanium dioxide (for white markings) and lead-free pigments for yellow road markings. These pigments provide the bright colors needed for visibility and road safety.

• Glass Beads: Retro-reflective beads are embedded in the paint to enhance visibility, especially at night or in low-light conditions. These beads reflect headlights back to the driver, improving road safety.

• Fillers: Materials like calcium carbonate, silica, or other minerals are added to improve the physical properties of the paint, such as its texture, durability, and wear resistance.

• Additives: These may include anti-UV agents, plasticizers, and stabilizers to improve the longevity and performance of the material.

Key Characteristics of Thermoplastic Paint:

1. Thermoplastic Nature:

   • The term "thermoplastic" refers to materials that become soft when heated and harden when cooled. Thermoplastic paint remains solid at room temperature but becomes liquid when heated to 180–220°C for application.

2. Fast Drying and Quick Reopening:

   • Thermoplastic paint solidifies quickly as it cools after being applied. This fast drying time means roads or other surfaces can be reopened to traffic almost immediately after the application, minimizing downtime.

3. Durability:

   • Once hardened, thermoplastic paint is extremely durable, making it resistant to abrasion, weathering, and chemical damage. It is designed to withstand high traffic volumes, UV exposure, and harsh environmental conditions, including heavy rain or snow.

4. Reflectivity:

   • Thermoplastic paint contains glass beads embedded in or scattered onto its surface. These beads help reflect light from vehicle headlights, making the markings highly visible at night or in low-light conditions, which is especially important for road markings.

5. High Adhesion:

   • It adheres well to various surfaces such as asphalt, concrete, and steel, which is why it is commonly used for road markings, airports, sports courts, and industrial floor markings.

Advantages of Hot Melt Paint:

• Cost-effective: While the initial cost may be higher, its longevity and durability make it a cost-effective solution in the long term.

• Fast Application: Due to its quick-setting properties, roads and areas can be reopened to traffic almost immediately after application.

• High Durability: Withstands extreme weather conditions, vehicle wear, and other external factors.

Applications of Hot Melt Road Marking Paint:

1. Road Markings:

   • Lane lines, pedestrian crossings, traffic symbols, and other road markings are often made with thermoplastic paint. The durability and visibility of these markings ensure safety and guidance on busy roads and highways.

2. Parking Lots:

   • It is frequently used for parking space lines, handicap symbols, directional arrows, and other markings in parking lots, both indoors and outdoors.

3. Airport Runways and Taxiways:

   • Thermoplastic paint is used in airports for runway markings, taxiway lines, hold position markings, and other crucial signage because of its high durability and resistance to wear from aircraft traffic.

4. Industrial and Commercial Areas:

   • It is used to mark aisles, safety zones, storage areas, and restricted zones in warehouses, factories, and distribution centers.

5. Sports Courts:

   • It is commonly applied to mark lines on basketball courts, tennis courts, volleyball courts, and other outdoor recreational surfaces.

6. Bicycle Lanes and Pedestrian Pathways:

   • Used to create visible bike lanes, pedestrian paths, and safety zones in urban infrastructure.

             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.
