High-Performance Thermoplastic Paint for Road Markings with
Quick-Drying and Durable Performance
Product Description
Thermoplastic road marking paint is a kind of coating widely used
for road markings. Here is the relevant information:
Composition
- Synthetic Resin: It's the main component, such as thermoplastic
acrylic resin and petroleum resin. It has adhesiveness and quick -
drying properties, enabling the paint to adhere to the road surface
and thermally fuse.
- Pigments: Common ones include titanium dioxide and zinc oxide for
white, and heat - resistant chrome yellow and organic yellow
pigments for yellow. They are for coloring and covering.
- Fillers: Such as calcium carbonate, talcum powder and silica
powder. They can enhance the mechanical strength, wear resistance
and color of the coating film.
- Reflective Materials: Mainly glass beads, which can improve the
visibility, brightness and durability of the markings at night.
- Additives: Including plasticizers, stabilizers and dispersants.
They can improve the performance of the paint, like increasing the
flexibility of the coating film, improving cold resistance and
preventing pigment precipitation.
Performance Characteristics
- Quick - drying: Regardless of the climate, it can dry in a short
time after the glass beads are spread. It hardens quickly in cold
seasons and slowly in warm seasons.
- Adhesion: It adheres well to the road surface and is not easy to
peel or break. When used on a cement road surface, a primer needs
to be applied in advance to enhance the adhesion.
- Visibility: The visibility during the day depends on the quality
of the pigments. The visibility at night, that is, the
reflectivity, depends on the quality of the glass bead spreading
and the control of the construction temperature.
- Durability: It has good wear resistance and weather resistance,
can adapt to different climate conditions and road conditions, and
has a long service life.
Application Range
It is suitable for a variety of road sites, such as the center
lines, lane dividing lines and edge lines of expressways and urban
roads. It's also applicable to parking lots, crosswalks and
intersections. It can also be used in airport runways, taxiways and
industrial areas where traffic management and safety signs are
needed.
Advantages and Disadvantages
- Advantages: It has good wear resistance, reflectivity and
durability, and can maintain the clarity and visibility of the
markings for a long time. It dries quickly and the traffic can be
opened shortly after construction, with little impact on traffic.
It can be mixed into various colors according to needs to meet
different marking requirements. The construction is relatively
simple and doesn't require complicated equipment and techniques.
- Disadvantages: Construction requires heating equipment and has
high requirements for the construction environment and conditions.
The paint price is relatively high and the initial investment cost
is large. Construction in a low - temperature or humid environment
may affect the quality and performance of the markings.
Detailed Process of Thermoplastic Paint Construction
1. Prepare the Surface
- Cleaning: Ensure the surface is free of dirt, grease, oil, dust, and loose
debris.
- Repair: Fix cracks or uneven areas to create a smooth surface.
- Drying: The surface must be dry to ensure proper adhesion
2. Mark the Layout
- Use chalk, tapes, or temporary markers to outline the areas to be
painted (lines, symbols, or shapes).
- Verify measurements against specifications or local standards.
3. Heat the Thermoplastic Paint
- Use a melting kettle or thermoplastic preheater to melt the paint.
- Heat to the recommended temperature, typically 180–220°C (356–428°F).
- Avoid overheating, as it may degrade the paint and affect quality.
- Stir continuously to ensure uniform consistency.
4. Primer Application (if required)
- Apply a primer to the surface if recommended by the manufacturer.
- This is especially needed for non-porous surfaces like concrete or
asphalt.
- Allow the primer to dry before applying the paint.
5. Apply the Paint
- Screed Method: Use a screed box to create uniform thickness for road markings.
- Spray Method: Use a spray machine for even application on large or irregular
areas.
- Extrusion Method: For thicker, raised markings.
- Hand Application: For small areas or repairs, manually pour and spread the molten
paint.
- Preformed Thermoplastic: Lay pre-cut sheets or symbols on the surface and heat with a
propane torch until adhered.
6. 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.

Tips for Safe and Effective Application
- Protective Gear: Wear gloves, heat-resistant clothing, and safety goggles.
- Temperature Control: Monitor paint temperature to avoid overheating.
- Traffic Management: Use barricades or warning signs to manage traffic during
application.
- Weather Conditions: Avoid application during rain or extreme temperatures.
By following these steps, thermoplastic paint can be effectively
applied to create durable, high-quality road or surface markings.
How to Select Suitable Thermoplastic Paint
Choosing the right thermoplastic paint for road marking depends on
several factors to ensure durability, visibility, and compliance
with standards. Here are the key considerations:
1. Application Environment
- Climate Conditions: Consider weather conditions such as temperature, humidity, and
rainfall. Some paints are specifically formulated for extreme
temperatures or high-moisture areas.
- Traffic Volume: High-traffic areas require more durable paints with better wear
resistance.
- Surface Type: Ensure compatibility with the road surface material (e.g.,
asphalt or concrete).
2. Performance Requirements
- Durability: Select a paint with high resistance to wear and tear, especially
for heavy-traffic roads.
- Reflectivity: Opt for paints that allow for the embedding of glass beads to
enhance nighttime visibility.
- Skid Resistance: For safety, especially in wet conditions, choose paints with
anti-skid properties.
3. Compliance with Standards
- Check if the paint complies with local regulations and standards
for road markings, such as color, thickness, and reflectivity.
4. Application Method
- Some paints are designed for specific application methods, such as
spray, screed, or extrusion. Choose paint compatible with your
equipment.
5. Color and Visibility
- Select colors with high contrast to the road surface (e.g., white,
yellow) and UV-stable pigments to prevent fading.
6. Drying Time
- In high-traffic areas, choose a fast-drying formula to minimize
disruption.
7. Cost Efficiency
- Balance initial cost with long-term performance. High-quality
thermoplastic paint might have a higher upfront cost but longer
durability, reducing maintenance expenses.
8. Supplier Reliability
- Purchase from reputable manufacturers or suppliers who provide
quality assurance, technical support, and consistent product
performance.
By considering these factors, you can choose thermoplastic paint
that meets your project’s specific needs and ensures long-lasting,
high-quality road markings.
