Application and characteristics of hot melt marking coatings

The difference between hot-melt marking paint and other road markings is that it does not contain solvent volatile components. During the construction process, the electrostatic powder is heated and melted, and then coated on the ground with professional equipment. After solidification, it becomes a bright label. Therefore, the coating principle does not depend on the evaporation of the general marking coating, but on the physical curing. Hot melt coatings have the advantages of fast drying, strong wear resistance, and night time reflection during construction, gradually expanding their scope of use. Applicable to key urban roads.

The coating of hot-melt logo coatings is much thicker than other logo coatings (generally, the usage of hot-melt logo coatings with a thickness of 1.5-2mm is about 4-5kg/m2). The price of hot-melt coatings is cheaper than other architectural coatings, but the total area of enterprise coatings is very large, usually several times higher than that of logo coatings at room temperature, which is not suitable in economically underdeveloped areas. In addition, hot melt coatings have higher requirements for real-time road conditions and are used for new road surfaces. Not suitable for asphalt roads with long-term aging and cracking.

Road marking construction includes marking coatings and hot melt coatings, both of which are rapidly developing. Road marking construction. Under modern scientific and technological theories, chemical raw materials such as epoxy resin are used in coatings. Using copolymers, modified materials, and modern generation methods to produce coating type epoxy resin raw materials, and then conducting scientific research, a new type of road marking construction and marking coating with outstanding performance, high quality, low cost, and suitable for modern road marking construction has been developed.

Improve the corrosion resistance and water resistance of coatings, ensure the basic characteristics of coatings, reduce solvent evaporation, and enhance coating adhesion. The coating is in powder form at room temperature and does not contain volatile solvents. Engineering construction heating and melting, equipment application on the ground, solidification and drying of solid coating film. Good practical application effect:

(1) It has the characteristic of rapid drying: it can be dried and opened to traffic within 1-3 minutes after painting, and can be used for construction without blocking traffic.

(2) Good usage effect: The hot melt surface coating has clear lines, sharp edges, and strong layering.

(3) Excellent wear resistance: The paint coating is durable and has been used for road markings for 2 years.

(4) Nighttime backlighting: Glass beads are added to the hot melt coating. During the construction process, the glass beads can scatter on the surface of the coating, making the actual backlighting effect faster, reducing traffic accidents, and complying with modern traffic rules.
