Whether in the new concrete road surface or in the old asphalt road surface, the old line cover the condition must be used to professional traffic marking construction under the coating agent. In the whole process of the construction of hot melt traffic marking, the undercoating is an important reason for whether the traffic marking falls down. The undercoating agent plays an important role in marking paint.

New asphalt road surface, with a lot of asphalt organic matter, it and industrial coatings in the adhesive material petroleum resin has random mixing and melting, in addition to building construction temperature 180-220°C. It is higher than the melting point of leaching, in the construction site, between petroleum resin and leaching (has been melted) mixed into a whole, the road and traffic lines in the middle of the no clear web page, thereby improving the role of the force between each other.

And concrete pavement itself as the water absorbing capacity of compound, corporate image, concrete road surface is water soluble, and small bonding between petroleum resin, and concrete for the bending rigidity pavement deformation is small, and industrial paint itself for thermosetting plastics, when the day is cold, also for the stiffness, strength and general asphalt pavement under the coating agent for non structural adhesive. To combine the two, it will require it to have a very good plasticity, in addition, traffic line markings in use will be the impact of the various directions, and this in turn requires concrete resilience of paint should be high quality, and the asphalt pavement and caused a whole industrial coatings, with the concrete pavement and industrial coatings for extracting the situation is different, Therefore, the concrete road surface should have a coating agent. Because the old asphalt road surface is less asphalt, the sand and stone have been shown in the road surface, so the characteristics of the concrete road surface is close to the concrete road surface. Generally, the concrete road surface coating agent or the service facility coating agent is also used.

As can be seen, no matter which kind of road surface, must be applied to the appropriate undercoating. Hope the line paint manufacturer's detailed explanation is helpful to you.
