Thermoplastic Paint
Thermoplastic is a durable, long-lasting marking material used particularly for road lines, car parks and traffic markings. Fast drying and with high resistance to wear, this type of material delivers excellent performance in areas with heavy traffic. Thermoplastic is applied to the surface by a hot-application method and forms a strong bond.
Providing both safety and a good appearance with their high durability and visibility, thermoplastic materials are resistant to UV, chemicals and environmental effects. They can also be tailored to different requirements with a wide range of colours.
Advantages of Thermoplastic Road Marking:
High Durability: Provides superior resistance to traffic density and environmental effects.
Fast Drying: Becomes ready for use quickly after application.
Long Life: Remains in place for many years thanks to its wear-resistant structure.
Visual Impact: Improves traffic safety by providing high visibility.
Environmental Resistance: Resistant to UV and chemicals.
Areas of Use for Thermoplastic Road Marking:
Road Lines: Ideal for lane divisions and traffic management.
Car Parks: Used for parking bays and directional markings.
Traffic Markings: Preferred for pedestrian crossings, arrows and warning symbols.
Industrial Areas: Applied as directional lines in warehouses and production facilities.
The Thermoplastic Application Process:
Surface Cleaning: The surface to be marked is cleaned and prepared.
Heating the Material: The thermoplastic material is melted at a specified temperature for hot application.
Application: The material is applied to the surface with special machines and a strong bond is achieved.
Inspection: Durability and visibility are tested after application.

The Working Principle of the Thermoplastic System
Extrusion Application
The molten material is laid onto the surface through a special shoe (die). A thick line with sharp edges is obtained; because the material thickness is high, its life is long.
Spray Application
This forms a thinner film and allows rapid progress over large areas. Material consumption is lower, but the service life is shorter than with extrusion.
Profiled (Rumble) Application
Raised ribs are formed on the line at regular intervals. When a vehicle reaches this area it generates vibration and noise to alert the driver; it also maintains visibility in wet weather by allowing water to drain away.
The Application Process
1. Heating the material: The material is heated in a stirred kettle to around 180–200 °C. Temperature control is critical; overheating breaks down the binder.
2. Surface preparation: The surface is cleaned and dried. Where necessary a primer is applied to improve adhesion.
3. Application: The molten material is applied by extrusion or spray; glass beads are broadcast at the same time.
4. Cooling: The material cools and solidifies within minutes and can be opened to traffic.
5. Inspection: The thickness, line width and bead distribution are checked; retroreflectivity is measured if required.
Technical Notes and Standards
The performance requirements are given in TS EN 1436, and the material properties in TS EN 1871 .
As the thickness increases the life is extended, but so are the cost and material consumption; the optimum thickness is chosen according to the traffic load.
Exceeding the application temperature causes the material to yellow and to lose strength.
Thermoplastic can suffer adhesion problems at low surface temperatures; the use of a primer becomes important in the winter months.
Frequently Asked Questions
How long does thermoplastic marking last?
This depends on the applied thickness and the traffic density. Lines applied thickly by extrusion last far longer than sprayed applications. In lanes with heavy vehicle traffic, wear accelerates markedly.
Why is it applied hot?
Thermoplastic material is solid at room temperature. When heated it becomes fluid, spreads over the surface and solidifies as it cools to form a thick film. This means it can be opened to traffic within minutes, without waiting for solvent to evaporate.
Can a new thermoplastic line be applied over an old one?
If the existing line is sound and bonded to the surface, a new coat can be applied over it. However, if the thickness increases excessively there is a risk of the edges breaking away. It is sounder to remove worn and loosened old layers by milling.
Can it also be used on a concrete floor?
It can, but a suitable primer is needed for adhesion on concrete surfaces. In indoor areas and on concrete floors, epoxy and polyurethane systems are generally preferred; thermoplastic is mainly for asphalt and outdoor applications.
