High quality hot melt Powder Coating reflective thermoplastic road
marking paint
Product Description
Thermoplastic Road Marking Paint is a durable, heat-activated paint applied to road surfaces to
create clear, long-lasting traffic markings, such as lane lines,
pedestrian crossings, symbols, and road signs. It is composed of a
blend of resins, pigments, fillers, and glass beads, designed to
ensure excellent visibility and resistance to wear and
environmental conditions. Here's a more detailed description of its
components, properties, and application:
Components:
1. Resins: These are the base material that gives the paint its structure.
Common resins include alkyd, acrylic, and thermoplastic resins,
which are chosen for their ability to bond strongly to road
surfaces and form a hard, durable layer once cooled.
2. Pigments: These provide color to the road markings. White and yellow are
the most common pigments, though other colors can also be used
depending on the marking requirements.
3. Fillers: These are inert materials used to bulk up the paint and help with
the application. They often include limestone, calcium carbonate,
or other fine powders.
4. Glass Beads: Tiny glass beads are embedded into the surface of the
thermoplastic marking. These beads enhance the retroreflectivity of the paint, meaning they reflect light back towards the source
(e.g., headlights from vehicles) for improved visibility at night
or in low-light conditions.
Key Features:
1. Heat-Activated: Thermoplastic paint is applied in a molten form, typically heated
to a temperature between 375°F to 400°F (190°C to 204°C). It is spread onto the road surface and immediately hardens upon
cooling, forming a solid, durable coating.
2. Durability: Once applied, thermoplastic paint creates highly resistant
markings that can withstand wear from traffic, environmental
factors like rain and sunlight, and abrasion from tires. It is
particularly effective in areas with heavy traffic.
3. Fast Drying Time: Since it hardens quickly upon cooling, thermoplastic paint allows
roads to be reopened to traffic sooner compared to other types of
road marking paints. This is a key benefit for high-traffic areas
or where lane closures need to be minimized.
4. Retroreflectivity: The glass beads embedded in the paint provide a reflective
surface that improves visibility, particularly in low-light
conditions such as nighttime driving or during poor weather. This
enhances safety by making road markings more visible to drivers.
5. Weather Resistance: Thermoplastic markings are resistant to UV rays, rain, snow, and
chemicals like oil and fuel, which means they maintain their color
and visibility for longer than many other types of markings.
6. Thickness and Customization: Thermoplastic paint is often applied in varying thicknesses,
depending on the traffic volume and marking requirements. Special
formulations, such as thick-film thermoplastic paint, are available
for areas with very heavy traffic or extreme wear.
7. Environmental Resistance: It can handle high temperatures and harsh weather conditions.
Unlike other paints, thermoplastic markings do not fade or peel
easily under UV exposure.
Detailed Process of Thermoplastic 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.
