Road Marking Line Customized Standard Reflective Paint Hot Melt
Road Marking Paint For Road Line Marking
Product Description
Hot melt road marking paint is used for creating road markings like
lines, symbols, and safety indicators on roads, highways, and
parking lots. It’s a thermoplastic paint that becomes liquid when
heated and solidifies as it cools down. Here’s how you typically
use it:
1. Prepare the Surface:
- Clean the Road Surface: The area should be clean and dry. Remove dirt, debris, dust, oil,
and any loose material using a broom, pressure washer, or cleaning
equipment.
- Dry the Surface: Make sure the surface is free of moisture before applying the
paint.
2. Heat the Paint:
- Use a Heating System: Hot melt road marking paint needs to be heated to around
180–200°C (356–392°F). Use a dedicated melting pot or heated tank
to melt the paint.
- Maintain Proper Temperature: Keep the paint at the right temperature to ensure even
application. It should be fluid enough to spread but not too hot to
cause burns or uneven application.
3. Apply the Paint:
- Choose the Right Equipment: Use a road marking machine (manual or automatic) designed for hot
melt paint. These machines often have an applicator that controls
the flow of the paint.
- Apply Evenly: Pour or spray the melted paint onto the prepared surface in a
uniform layer. The paint will begin to solidify as it cools, so
work efficiently.
- Marking Width and Thickness: Depending on the machine, adjust the settings to achieve the
correct width and thickness for the lines or symbols you are
marking.
4. Allow Cooling and Solidification:
- Cooling Time: After application, the paint will solidify relatively quickly as
it cools down. This can take just a few minutes, depending on the
weather and temperature.
- Curing: Full curing might take a few hours. Ensure that traffic doesn’t
pass over the markings too soon to prevent smudging or damaging the
lines.
5. Clean Equipment:
- Clean the Machine: After use, clean your equipment thoroughly, especially the nozzle
and hoses, to prevent the paint from hardening inside the machine.
Composition Ingredients
- Synthetic Resin: It is the main component of thermoplastic road
marking paint, such as rosin and its derivative modified resins,
petroleum resins, polyester resins, etc. It has adhesive properties
and quick-drying characteristics, enabling the paint to adhere to
the road surface and bond through hot melting.
- Glass Beads: Usually with a diameter of 0.1-1.4 millimeters, they
are colorless and transparent. They can improve the recognizability
of the markings at night, enhance brightness and durability, and
also protect the markings from wear.
- Pigments: Mainly white and yellow, such as titanium dioxide, zinc
oxide, heat-resistant chrome yellow, organic yellow pigments, iron
oxide, etc., which play a role in coloring and covering.
- Fillers: Such as calcium carbonate, sand, etc., which can ensure
the mechanical strength, wear resistance, and color of the paint.
The particle size of the fillers will affect the fluidity,
sedimentation degree, and surface finishing of the paint.
- Additives: They can increase the plasticity of the coating,
making it resistant to sedimentation, pollution, and fading.
Features and Advantages of Hot Melt Road Marking Paint
- Good Quick-drying Property: After the marking is coated and the
glass beads are sprinkled, it can dry within a short time (less
than 5 minutes), reducing the interference with traffic.
- Excellent Visibility: During the day, the visibility is ensured
by high-quality pigments. At night, through the reflection of the
glass beads, the markings are distinct, uniform, and clear, with
sufficient visibility distance.
- Strong Adhesion: It adheres firmly to the road surface and will
not easily peel off or crack due to the rolling of vehicles,
skidding, braking, or the thermal expansion and contraction of the
road surface caused by seasonal temperature changes.
- Outstanding Durability: It has good abrasion resistance and
weather resistance, can adapt to different climatic conditions and
road surface conditions, and has a relatively long service life.
