High-Performance BS 3262 Hot Melt Road Marking Paint Durable and Eco-Friendly for Long-Lasting Markings

                                  Product Description                                      

BS 3262 Hot Melt Road Marking Paint is a British Standard specification for thermoplastic road marking materials designed to provide durable, highly visible, and long-lasting road markings. This standard ensures that the hot melt road marking paint meets specific requirements for performance, safety, and environmental considerations.

Key Features of BS 3262 Hot Melt Road Marking Paint:

1. Composition:

   • Thermoplastic Resins: The paint is made from a blend of thermoplastic resins, which allow it to be melted and applied in a molten state. When it cools, it solidifies into a durable, hard surface.
   • Pigments: Typically includes titanium dioxide for white markings and lead-free yellow pigments, ensuring bright, high-visibility colors.
   • Glass Beads: Retro-reflective glass beads are embedded in the paint to enhance visibility, especially at night or under low light conditions.
   • Fillers: Materials like calcium carbonate or silica are used to adjust the paint's texture and improve its wear resistance.

2. Durability:

   • Designed to withstand heavy traffic, environmental wear, and extreme weather conditions, including UV rays, rain, and temperature fluctuations.
   • Excellent abrasion resistance, making it suitable for high-traffic areas where road markings need to endure wear and tear over time.

3. Fast Drying:

   • The paint sets quickly after application, reducing downtime and allowing traffic to resume soon after application. This is especially important for minimizing disruption on busy roads and highways.

4. High Reflectivity:

   • The embedded glass beads ensure high retro-reflectivity, improving the visibility of road markings during night driving or in poor weather conditions.
   • The retro-reflective properties are enhanced by the glass beads, which help to bounce headlights back to drivers, improving safety.

5. Skid Resistance:

   • The paint provides a skid-resistant surface, which is particularly important for preventing accidents in areas with high traffic volume or high-speed zones.

6. Application Temperature:

   • The paint is applied at a temperature range of 180°C to 220°C (356°F to 428°F), making it essential to use specialized equipment designed for hot melt thermoplastic materials.

7. Environmental and Safety Compliance:

   • BS 3262 emphasizes environmentally safe practices. Modern formulations are designed to be free of harmful substances like lead, and they aim to minimize volatile organic compound (VOC) emissions.
   • The paint should be non-toxic and safe for workers applying it.

Advantages:

• Longevity: Offers a long-lasting solution for road markings.
• High Visibility: Provides clear, reflective markings that improve safety for drivers.
• Cost-Effective: Despite the initial investment in materials and equipment, the durability and low maintenance needs of BS 3262 hot melt paint make it cost-effective in the long term.

Detailed Process of Hot Melt Road 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.
