Thermoplastic paint is a road marking material based on
thermoplastic petroleum resin, with high-quality pigments and
additives as auxiliary materials. The marking line used as the raw
material has the advantages of quick-drying, easy construction,
good light reflection, and long service life. According to
different product production standards, Huaqun brand hot melt
marking paint is divided into national standard (including standard
national standard, derivative national standard), American
standard, British standard, and custom label.
Overview Thermoplastic Paint for Road Marking
Composed of petroleum resin, EVA, PE wax, color filler, and other
materials. It is in powder form at a normal temperature. It is
heated to 180-200°C with hot kettle. It has the characteristics of
a linear shape, good abrasion resistance, etc., and the reflective
microbeads are scattered on the construction surface, which has a
good reflective effect at night. It is widely used in highways and
urban roads.

How to Use Thermoplastic Paint for Road Marking
The hot-melt marking paint is solid powder at normal temperature.
During the construction, the paint is put into the melting kettle.
The temperature in the kettle is controlled between 180 °C and 210
°C, and stirred while melting. After melting and flowing, Place in
the insulated melt hopper of the scribbling car. The molten coating
is then introduced back into the scoring hopper and held warm to
maintain the material in a molten state. Before the scribbling,
there is a pre-marking machine marking position, and the primer is
applied by a lower coating machine at the coating position
indicated by the design icon. After the primer is completely dried,
the marking paint can be applied. When starting the scribbling, the
scribbling bucket should be placed on the road surface. Because
there is a certain gap between the scribbling bucket and the
ground, when the scribbling car is moving forward, a neat marking
line is scraped by an automatic rogue. The glass bead spreader
automatically and evenly spreads a layer of reflective glass beads
on the marking line.
