Professional Thermoplastic Paint for Clear and Long-Lasting Road
Markings
Product Description
Thermoplastic paint is a kind of paint specifically designed for
marking roads, parking lots, and other traffic - related areas.
It is a thermoplastic material. At normal temperature, it's in a
solid state. When heated to a certain temperature (usually around
180 - 220 degrees Celsius), it turns into a viscous liquid that can
be easily applied to the road surface.
This type of paint contains resins such as petroleum resins and
rosin resins. These resins provide good adhesion to the road
surface and help the paint to solidify and form a durable marking
after cooling. It also includes fillers like calcium carbonate and
titanium dioxide. Fillers can improve the hardness and visibility
of the markings. Pigments are added to give the paint different
colors, such as white, yellow, or other colors required for traffic
signs and lane markings.
Once applied and cooled, thermoplastic road - marking paint forms a
thick, wear - resistant layer. It can withstand the abrasion of
vehicle tires, exposure to sunlight, rain, and other weather
conditions, and maintain clear markings for a long time to ensure
traffic safety and order.
Application
Here's how to use thermoplastic road marking paint:
Preparation
- Surface cleaning: Thoroughly clean the surface where the coating
will be applied. Remove dirt, grease, rust, and other contaminants.
You can use detergents, solvents, or mechanical methods such as
sandblasting for better adhesion.
- Priming (if necessary): In some cases, a primer may be needed to
enhance the bond between the substrate and the hot - melt coating.
Make sure the primer is compatible with the coating and the
substrate and follow the primer's application instructions.
Heating and Application
- Heating the coating: The thermoplastic hot - melt coating
material needs to be heated to its melting point. This is usually
done in a specialized heating equipment such as a hot - melt kettle
or a melter. The temperature should be carefully controlled
according to the manufacturer's recommendations to ensure the
coating is in the proper liquid state for application.
- Application methods:
- Spraying: The molten coating can be sprayed onto the surface
using a hot - spray gun. This method is suitable for large - area
applications and can provide a relatively even coating thickness.
However, it requires proper spraying techniques to avoid over -
spraying or an uneven finish.
- Extrusion: For applications like road - marking, the hot - melt
coating can be extruded through a nozzle directly onto the road
surface. The extrusion rate and the movement speed of the equipment
need to be coordinated to achieve the desired width and thickness
of the coating.
- Roll - coating: A hot - melt roll - coating device can be used to
apply the coating. The molten coating is transferred from a
reservoir to a roll and then onto the surface. This method is good
for flat surfaces and can provide a smooth coating.
Post - Application
- Smoothing and leveling: Immediately after application, if needed,
use tools such as a squeegee or a trowel to smooth and level the
coating to get the desired surface finish. This step should be done
quickly before the coating starts to cool and solidify.
- Cooling and curing: Let the coating cool down naturally to
solidify. The cooling time depends on factors such as the ambient
temperature, the thickness of the coating, and the type of
thermoplastic material. Avoid disturbing the coating during the
cooling process to ensure it cures properly and forms a durable
film.

Advantages of Thermoplastic Road Marking Paint
Advantages of thermoplastic paint are as follows:
1. Good adhesion: It can firmly adhere to various substrates such
as asphalt and concrete, ensuring the integrity and clarity of the
markings for a long time. This is crucial for the durability and
legibility of road markings.
2. Long service life: The material is highly resistant to abrasion,
impact, and weathering. It can maintain its performance and
appearance for an extended period, reducing the need for frequent
reapplication and saving maintenance costs. For example, in
high-traffic areas, thermoplastic paint can withstand the
continuous wear and tear of vehicles.
3. Quick drying: After application, it solidifies rapidly, usually
within a few minutes. This allows for quick completion of the
painting work and minimizes the disruption to traffic or other
activities. It is especially important for road construction and
maintenance projects where minimizing traffic congestion is a
priority.
4. Bright color and good visibility: The paint can provide vivid
colors, making the markings highly visible during the day.
Additionally, when glass beads are added, it has excellent
reflective properties at night, enhancing the safety of driving by
enabling drivers to clearly see the markings even in low-light
conditions.
5. Wide application range: It is suitable for a variety of surfaces
and locations, including roads, parking lots, airports, and other
transportation facilities. It can be used to mark different types
of lines
, such as lane dividers, stop lines, pedestrian crossings, and
parking spaces.
6. Cost-effective: Although the initial investment in equipment and
materials may be relatively high, considering its long service life
and low maintenance requirements, it is cost-effective in the long
run. Moreover, the availability of raw materials and the maturity
of production technology contribute to its relatively stable price.
7. Environmental adaptability: It can perform well in different
environmental conditions, such as high and low temperatures,
humidity, and rain. It is not easily affected by extreme weather,
ensuring the stability and reliability of the markings.
