The reason for the slow drying of the hot melt marking after construction

1. The ambient temperature specified in the standard is 23. The drying time of the hot melt marking line is 23 degrees, not more than 3 minutes. If the ambient temperature is greater than this, the drying time should be extended accordingly.

2. High pavement temperature: After the construction of the hot-melt marking, due to the high temperature of the pavement, the asphalt pavement is hot in summer, and the temperature is as high as 60 degrees. This phenomenon is generally prone to occur during the noon time period (around 11 am to 16 pm).

In particular, the double yellow line in the middle of the road surface is particularly serious. Because the sunshine hours in the middle of the road are long, the heat dissipation is slow.

3. The problem of the marking coating itself, the use of resin, wax and other raw materials with low softening point and the use of white oil will also slow down the cooling process of the hot melt marking line, and the marking line will be soft.

4. Adding excessive leveling agents and other additives and things to improve leveling to reduce the cost of the coating will also reduce the softening point of the marking coating, and will also make the hot melt marking slow to dry and the marking line soft.

To sum up, the first thing to pay attention to in the construction of hot melt marking is to choose the hot melt coating produced by regular manufacturers that meets the national standards.

There are many factors that affect the drying time of hot melt marking construction, there are reasons for the coating itself, there are also reasons for construction, the softening point of the resin is relatively low, it is easy to lead to a long drying time, too many additives are added to slow down the drying, and the ambient temperature is too high when it will also affect the drying and forming of the marking. --Land Rover Traffic Hot Melt Marking Coatings.

What causes the hot melt marking coating to not dry after application? Hello pro 1The ambient temperature of the hot melt marking specified in the standard is about 23.

This is something that many people understand. The drying temperature of the hot-melt marking coating is about 23 degrees, and it can be dried in about 1 minute. 2.

High pavement temperature: After the construction of hot-melt marking coating, due to the high pavement temperature, the asphalt pavement oil temperature rises in summer, and the temperature may be as high as 60 degrees at noon. When the temperature of the hot melt coating drops to about the same level as the road surface, the material is difficult to cool and therefore dries slowly.

It is worth mentioning that the double yellow line in the middle of the road has a higher chance of this happening. Because of the long sunshine in the middle of the road, the temperature is naturally higher than in other places where the heat is dissipated. 3.

Problems with the hot melt marking coating itself. Adding too much leveling agent and other additives to improve leveling to reduce coating costs, and a lower softening point of the paint can also affect its drying time.
