Why Two-Component Marking Paints Are More Suitable for Heavy Traffic Sections?

 

 

There are roughly three types of road marking paint on the market, namely: waterborne marking paint, hot melt marking paint, and two-component marking paint. So, what are the differences between these types of markings, and which type is more suitable for heavy traffic sections?

 

1.      The waterborne marking paint has poor wear resistance and can only be used for about three months to half a year. Moreover, because the paint itself does not adhere firmly to the glass beads, the marking does not have reflective performance; despite the construction and maintenance efficiency of the marking project higher, but it’s not that appreciate to be used in heavy traffic sections. Usually，waterborne markings are more suitable for first- and second-level highways in cities and sections with less traffic.

 

2.      The wear resistance of hot melt marking paint is better than the waterborne markings. It can be used for more than one year in heavy traffic areas. Usually，hot melt paints are mixed with drop-on glass beads to make road markings reflect light. However, since the main raw material of hot-melt marking paint is C5 petroleum resin, which is greatly affected by temperature changes, markings will become sticky under high temperatures in summer and easily adhere to dirt, especially in cities with serious environmental pollution, the markings will not be stain resistant.

 

3.      The two-component marking paint has the strongest wear resistance among the three and can be used for more than 2 years even on roads with heavy traffic. The main raw material of the two-component marking paint is methyl methacrylate, which prevents the two-component marking from being affected by temperature changes and wear-resistant and crack-resistant fibers after the marking is damaged. It also has a good effect on glass beads. The excellent adhesiveness prevents the glass beads on the marking surface from falling off easily. When carrying out marking maintenance, there is no need to remove the old markings. You only need to polish the surface of the old markings and then spray paint a layer of two-component high-brightness markings, thus further improving the efficiency of marking maintenance.

 

It's important to note that different manufacturers may have proprietary formulations or variations in resin types for road marking paints. Additionally, regional regulations and standards may influence the choice of resin for road marking applications.

 

The ultimate purpose of installing and maintaining road markings is to improve road safety; for this, high-quality raw traffic safety materials are essential.

How to Solve Bubbles in Road Markings？

 

 

 

All roads should be clean and dry during the marking construction. Moisture is the most harmful factor in the adhesion of paint and pavement. The amount of moisture in the ground is enough to affect proper coating adhesion. Early morning dew and fog usually result in wet roads. If there is too much moisture on the road surface, it usually leads to blistering of the hot melt markings. Blisters will form as surface bubbles and may not burst. If this happens, the marking construction should be stopped until the road surface is dry. The only way to determine the presence of moisture is to perform a test. There are many ways to test for moisture：

1. Place a 30cm square thin plexiglass plate (aluminum foil, etc.) on the road with tape, and seal the surrounding edges with tape. After 15 minutes, check the bottom of the board and the road surface. If the moisture is too much, do not hot melt marking construction.

2. Place a 45cm square tar paper on the road surface and coat it with hot melt paint heated to 215 degrees Celsius. Wait two minutes and pick up the tar paper. Check the underside. If there is moisture, do not hot melt construction.

The ultimate purpose of installing and maintaining road markings is to improve road safety; for this, high-quality raw traffic safety materials are essential.

Detailed Process of Hot Melt Marking Construction

 

 

 

1.    Road Cleaning

Before construction, the nearby area must be cleaned to ensure that there are no impurities such as oil, water, fallen leaves, weeds, etc., so as not to affect the adhesion, smoothness, and reflective effect of the markings.

 

2.    Full Scale Plotting

During the setting out process, calculations and measurements must be made strictly in accordance with the construction drawings. Measure the number of lanes that need to be marked on the road, fix the points, and then mark them with a slate pen. Use titanium dioxide or double flying powder to stick a hemp rope to stretch the line. After the rope is removed, make corrections and improve it to ensure that the line shape is clear and accurate.

 

3. Lower Coating Agent Application

The primer is a common adhesive used in hot-melt marking construction. Applying it on the highway pavement can make the hot-melt paint better adhere to the road surface.

 

4. Hot melt coating application construction

Before construction, first check the relevant coating equipment.

As the trolley moves forward, the paint will form a film on the road surface, and a layer of glass beads will be spread on the film during the coating process. When the trolley moves forward, use the reference waterline as the ruler to control the thickness and width of the markings to ensure the coordination, clarity, and smoothness of the markings at the connection between straight lines and curves.

Note: During the coating process, in order to avoid settling and separation of the paint, the paint needs to be stirred frequently.

 

5. Line modification and opening to traffic

After the paint application is completed, check and correct the marked line shape, check the spread of glass beads, etc. After confirmation, clean up the construction site.

After the markings are dry and hardened, the relevant construction equipment can be moved, safety facilities removed, and traffic opened.
