What impact does primer have on line paint?
【Summary Description】 Whether on new concrete pavements or old asphalt pavements, professional traffic line construction coatings must be used under old line coverage conditions. Throughout the entire process of hot-melt traffic line construction, the primer is an important reason for whether the traffic lines will fall off.
Whether on new concrete surfaces or old asphalt surfaces, a professional traffic line construction coating agent must be used under old line coverage conditions. Throughout the hot melt traffic line construction process, the primer is an important reason for whether the traffic line falls off. The primer plays a crucial role in paint markings.
New asphalt surfaces contain a large amount of asphalt organic matter, which has the characteristics of random mixing and melting with the adhesive material petroleum resin in industrial coatings. Additionally, the construction temperature is 180-220°C. This is above the melting point of the leachate, and on the construction site, the petroleum resin mixes with the leachate (which has melted) into a whole, without a clear webpage in the middle of the road and traffic lines, thus enhancing the effect of mutual force.
And the water absorption capacity of the concrete surface itself, corporate image, the concrete surface is water-soluble, and the combination with small petroleum resins results in minimal bending stiffness and deformation of the concrete surface. Thermosetting plastics and industrial coatings themselves, when cold, also have stiffness, and the strength of the coating agent under general asphalt surfaces is a non-structural adhesive. The combination of the two requires good plasticity. Furthermore, the traffic line uses different directional influences, which in turn requires that the elastic paint for concrete should be of high quality, and for asphalt surfaces, the extraction situation of the entire industrial coating differs from that of the concrete surface. Therefore, a coating agent should be used for the concrete surface. Due to the lower asphalt content on old asphalt surfaces, gravel has already appeared on the surface, so the characteristics of the concrete surface are close to that of the concrete surface. Generally, concrete surface coating agents or service facility coating agents are also used.
It is evident that regardless of the type of surface, an appropriate primer must be applied. I hope the detailed instructions from the line paint manufacturer are helpful to you.
