Thermoplastic Paint for Road Marking Durable and High-Performance
for Traffic Signs
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
Thermoplastic hot melt coatings have the following advantages:
1. Excellent adhesion: They can adhere well to a wide range of substrates such as metals,
plastics, and wood. This strong bonding ability ensures that the
coating stays in place and provides long - term protection.
2. Fast - drying and curing: These coatings dry and cure rapidly once applied. The quick -
setting nature allows for a shorter production or application time,
increasing productivity. For example, in road - marking
applications, traffic can be allowed back on the marked area
sooner.
3. Flexibility: They possess good flexibility. This property enables the coating
to withstand substrate movement without cracking or peeling. It can
adapt to the expansion and contraction of the underlying material
due to temperature changes or mechanical stress.
4. Chemical resistance: Thermoplastic hot - melt coatings can offer resistance to many
chemicals such as acids, alkalis, and solvents. This protects the
substrate from chemical damage in various environments like
industrial settings or outdoor conditions where chemical exposure
is possible.
5. Weather resistance: They have good resistance to weathering, including resistance to
ultraviolet (UV) radiation, rain, snow, and temperature
fluctuations. This makes them suitable for outdoor applications
where the coating needs to maintain its integrity and appearance
over time.
6. Ease of application: They can be applied using a variety of methods such as spraying,
extrusion, or hot - melt roll - coating. This versatility in
application techniques allows for efficient coating in different
situations and on different types of surfaces.
7. Recyclability: In some cases, thermoplastic hot - melt coatings can be recycled,
which is an environmentally - friendly characteristic compared to
some other coating types that are not recyclable.
