50 Common Questions on Hot Melt Road Marking Construction, Question 2: “Drying Time”
In the scorching summer, the drying time of the markings is particularly important. Slow drying not only affects the construction progress, but also makes the markings less resistant to dirt, causing them to turn black and, in severe cases, sticking to the tire. Why do the markings dry slowly? The reason is that when the […]
