Coating for road markings
Overview
Hot-melt marking paint is a type of coating applied to roads to
mark road markings. Road markings are safety signs, and in road
traffic, they are also a kind of silent "language".
Usage Overview
Hot-melt reflective pavement marking paint is mainly used on
highways and expressways of grade 2 and above. The coating
thickness of the markings made by this paint is (1.0 - 2.5) mm. The
paint contains reflective glass beads and during the marking
construction, reflective glass beads are scattered on the surface.
This type of marking has good night-time reflective performance and
a long service life. The demand for various road marking paints
depends on the traffic volume of the highway construction and the
quality of the paint itself. Generally, it can last for (2 - 3)
years. The construction of hot-melt paint requires special heating
equipment. When re-coating old markings, the thicker old coating
must be removed before applying the new coating.
Product Description
Composition:
It is mainly composed of resins, pigments, fillers, and additives.
The resins provide excellent adhesion and durability. Pigments give
it various colors for different application scenarios. Fillers
enhance the physical properties of the coating, and additives
improve its processing performance.
Features:
- High temperature resistance. It can maintain its integrity and
performance under relatively high - temperature conditions,
suitable for applications where heat exposure is a factor.
- Strong adhesion. It firmly adheres to a wide range of substrates
such as asphalt, concrete, and metal surfaces, ensuring long - term
stability.
- Good durability. Resistant to wear, weathering, and chemical
corrosion, making it ideal for both indoor and outdoor use.
Product Advantage:
Thermoplastic coatings have the following advantages:
Firstly, they have excellent flexibility. They can deform along with the
expansion and contraction of the substrate without cracking easily.
For example, on the surface of some metals that often have tiny
deformations, thermoplastic coatings can adhere well and remain
intact, just like putting an elastic "coat" on the surface.
Secondly, they have strong processability. They can be applied in a variety
of ways such as spraying, dipping, and brushing, which makes them
convenient to be used on the surfaces of objects with different
shapes and sizes.
Thirdly, they have good chemical resistance. They can resist the erosion
of many chemical substances. For example, common acid - base
solutions have less impact on them. In an industrial environment
with chemical substances, thermoplastic coatings can effectively
protect the coated objects.
Finally, they can dry and solidify quickly. This can reduce the
construction time and waiting time and improve work efficiency.
Applications:
- Road marking. Widely used for creating clear and durable markings
on roads, highways, and parking lots to guide traffic.
- Industrial floor coating. Provides a protective and anti - slip
layer on industrial floors, improving safety and durability.
