Two Component Road Marking Method

Two components marking paint consists of cold plastic paint and curing agent. When marking, the two components are mixed immediately before application to form the pavement marking. The service life of two component pavement marking normally ranges between 2 and 4 years based on traffic volumes.

Two-component pavement marking is used for marking project that need to be quickly applied such as car parks, road crossing and edge lines. The paint can be curing within 5-30 minutes depending on application method.

Two components marking have excellent performance on asphalt surfaces and are very resistant to snow plowing. Two component marking system is widely used in cold weather areas such as northern Europe.

Two component pavement marking paint is considered very expensive compared to other materials. In addition, special equipment is needed for applying two component pavement markings.

Two component road marking machine is equipped with two high pressure diaphragm pumps: one for cold plastic paint and another for curing agent. Changing the angle of two pumps will adjust the intersection point of paint and curing agent. While mixed, the curing agent will accelerate the forming speed of polymer methyl methacrylate pavement markings.

Two component marking system has many advantages compare to thermoplastic and cold solvent marking:

1. Quick applying. Rapid curing for less road blocking.

2. Exceptional adhesion to a variety of road substrates such as concrete and asphalt surfaces.

3. High retro-reflective. Glass beads and paint are tightly mixed.

4. Excellent weather resistance. Keep excellent performance in all temperature and weather.

5. Great wear and stain resistance. Long service life in poor conditions.

6. Environment friendly. Without solvent, the paint has little damage to environment.

Despite so many advantages, the cost of two component road marking is considered very expensive compared to other marking methods. Curing agent and special designed machines significantly increased the cost of road marking project. The structure of two component marking equipment is very complex, which leading to high maintenance cost. These all limit the application of this advanced marking method.
