The thermosetting property of the anti-corrosion coating is used for the hot-melt coating to make the hot-melt architectural coating fast and dry. The hot-melt property of the anti-corrosion coating is used to make the road markings firmly bonded to the ground. Hot melt coatings are generally composed of thermoplastics, pigments and fillers, reflective materials and other modifiers. The hot melt coating is powder at room temperature. Active solvent and coating evaporation component in the composition. It is melted by heating in engineering construction, and then coated on the road with professional machinery and equipment, and the film is solidified by condensation with the help of physics. For hot melt pavement architectural coatings, its fluidity is a very key performance index in the whole process of engineering construction.

1、 Strong adhesion:

There should be strong adhesion between road marking paint and pavement, so as to fully ensure the detail and clarity of road marking. As everyone knows, the less the drying time of general architectural coatings, the worse the adhesion. Therefore, this constitutes a pair of differences. One of the core technologies in the road marking coating industry is how to deal with this problem.

2、 Reflective performance at night:

Contemporary traffic travel not only stipulates the utility of day time, but also attaches importance to the actual effect at night. Returning light road markings at night can further improve the coefficient of driving at night, and at the same time, it can also improve the driving rate at night.

3、 Quick drying during construction:

The natural environment in which the road marking paint is applied has an uninterrupted traffic volume (even at night). Therefore, it is required that the road marking paint should dry as quickly as possible. According to different types of architectural coatings, it is generally required that the whole line be opened to traffic in a down-to-earth manner within 3 ~ 15min. For general road marking coatings, such regulations are almost too strict, but it is a prerequisite for considering whether a certain commodity can become a good road marking coating.

4、 Good water solubility:

It is stipulated that architectural coatings can always maintain freshness, of course, the embrittlement level is slow.

5、 Paint Rationality:

That is to say, it stipulates that architectural coatings have low cost and cost-effective market price.

6、 Green and low carbon:

In the whole process of scientific research, production, manufacturing and application of practical coatings, we can only try to meet the above provisions, but it is unlikely to meet the above provisions at the same time, so we can only focus on some aspects.
