Compared with high-quality MMA two-component reticles, hot melt reticles have a series of problems in their applications:
About the construction methodDuring hot melt construction, it is necessary to use liquefied gas to heat the material temperature to more than 180 °C, and there are fire and explosion hazards in open flame operation, and burns and scalding accidents often occur. In addition, the burning personnel feed up to 120-200 bags (25kg/bag) per day, mostly using walk-behind construction, which may lead to occupational diseases such as lumbar spine problems and alopecia areata all year round. Hot melt construction requires primer oil, which increases the process and is cumbersome to construct.In contrast, MMA two-component marking is constructed at room temperature, with a daily material of about 20 barrels (25kg/barrel), and spraying is self-sufficient, which is safe, easy, clean and convenient to construct, without primer, saving the process, improving efficiency and reducing costs.Hot melt coatings have poor weather resistance, are brittle at low temperatures, have poor flexibility, and crack and age quickly when the temperature difference between day and night is large. This not only affects the aesthetics of the paint, but also leads to its easy water seepage, dirt seepage, and even flake peeling, affecting the life of the marking.In contrast, high-quality MMA two-component markings have good weather resistance, do not absorb ultraviolet rays, are not affected by external temperature differences and thermal expansion and contraction, and do not have aging and cracking.
▲ Hot melt cracking
The hot melt marking has extremely poor adhesion on the cement pavement.
High-quality MMA two-component coatings have better adhesion and are more competitive than hot melt pavements on asphalt pavement and cement pavement with qualified grades.Hot melt markings will have uneven reflection during construction or after a period of time. This is due to the insufficient strength of the hot-melt main material, making it difficult to bond the glass beads firmly. When the wheel is crushed frequently, the glass beads can easily fall off. or when the road surface temperature and air temperature are high, the reticle will soften and press the glass beads into the reticle paint film, which will directly affect the reflective effect and reflective life. In addition, if there is a difference in material temperature during the construction process, the degree of settling of glass beads will also be inconsistent, which will affect the uniformity of reflection.In contrast, high-quality MMA two-component coatings form a dense paint film surface through a chemical cross-linking reaction that makes the glass beads bond strongly, resulting in longer-lasting reflections of the markings and a higher retroreflective brightness coefficient during (rainy) nights and wet roads. In the same case, after a period of traffic wear and tear, the reflection of high-quality MMA two-component is generally uniform, and there will be no shadow of a large number of glass beads falling off like hot melt, which will affect the aesthetic effect of night vision.

About repainting the markings
The strength of the hot melt main resin is poor, in order to prolong the life of the marking, only the thickness of the stroke or the number of recoats can be increased, and the thickness of each stroke is generally 1.5-2mm. If the thickness exceeds the standard, it will bring driving safety hazards. If it is controlled within the standard thickness, the marking line will be very thin when recoated, and the paint will solidify quickly after cold, so that the glass beads cannot be bonded firmly, resulting in the marking line not reflective.In contrast, high-quality MMA two-component spraying has a thickness of about 0.7mm each application, and after 2-3 years of construction, the two-component can be directly recoated, or the old line can be directly re-fused, and high-quality MMA two-component spraying is the most ideal choice for maintenance construction.After hot melt aging, it is necessary to remove the line before drawing. The hazards of water removal/mechanical line removal are: increased construction costs, waste of water resources, damage to the road surface and irreversible, high cost of line removal garbage recycling, road congestion, and increased management costs on the owner's side.In contrast, if the MMA two-component spraying marking needs to be rerouted, it can be directly sprayed and covered with MMA two-component coating paint, which has high efficiency and long life, and does not damage the pavement.
▲ Water removal lines cause great damage to the pavement and waste water resources
▲ For the part that needs to be rerouted, two-component covering and spraying can be used, which is highly efficient and does not damage the pavement
About low-carbon environmental protection
The VOC of hot melt bottom oil exceeds the standard, the combustion of liquefied gas releases carbon dioxide to pollute the environment, and the dust of coatings and line removal also pollutes the environment, which is not conducive to energy conservation and emission reduction. Frequent marking and removal of hot melt markings need to close the road, which can easily cause traffic jams, fuel consumption, and air pollution caused by automobile exhaust.In contrast, high-quality MMA two-component does not contain any harmful substances, and the coating has a high solid content of nearly 100%, which is basically non-volatile, green and environmentally friendly, and is in line with the national "dual carbon goal" policy.The long-lasting reflective properties of high-quality MMA two-component coatings are particularly excellent in environments where street lights are lacking or poorly lit, and can significantly improve road edge definition. Therefore, the number of street lights can be appropriately reduced and the brightness of the street lights can be adjusted, and the street lights can be turned off after midnight, which can save a lot of electricity. At the same time, it can also reduce the installation of road studs, contour markers, curb light strips and a large number of electroluminescent facilities, so as to reduce the burden on the country and the government and save money.Hot melt markings come off when shoveling snow.In contrast, premium MMA two-component reticles have strong adhesion and are not affected by snow shoveling and snow melting agents. Hot melt markings are easily soft and brittle under the influence of temperature, and are not wear-resistant. Especially on multi-vehicle vehicles, ramps, and roads with high traffic flow, wear out quickly and shorten the lifespan.In contrast, high-quality MMA two-component markings are harder than cement, and the anti-wear life can even be as long as 5-10 years under conventional road conditions and when the amount of paint meets the standard.Hot melt markings contain plasticizers, which will migrate, making the surface of the markings sticky and easy to stain dust. Especially in the south, the temperature is high, and the stain resistance of the marking line is poor.In contrast, high-quality MMA two-component coatings cure to form a dense paint film, which can effectively prevent the penetration of pollutants, and the coating is not affected by air temperature, and the surface will not become sticky, and will not adhere to sediment and dust. And, after rain and snow, rinsing with a sprinkler truck or high-pressure water gun, the markings will be as smooth as new.
The non-slip particles of the hot melt reticle are not firmly bonded and easy to fall off, and the anti-slip effect is poor.In contrast, high-quality MMA two-component anti-slip markings can firmly adhere to anti-slip particles, and the anti-slip value can still be greater than 55BPN after half a year, with a long anti-slip life, especially the good anti-slip effect of zebra crossings, which can better reduce accidents.On March 15, 2018, the reticle line fell off and the reticle was not reflective
▍ Reticle reflection and anti-slip are national mandatory standards

Sanwin two-component overall solution has strong international competitiveness
Looking at the world, two-component labeling systems are widely used in cold climate regions such as Northern Europe, Canada, and the United States. However, MMA two-component pavement marking coatings and equipment are generally considered very expensive compared to other materials. In addition, this advanced marking method requires engineers with more than ten years of experience to carry out construction. In terms of equipment, the price of Denmark's Borum and Germany's Hofmann equipment is more than 100-2 million. These specially designed equipment for curing agents significantly increase the equipment cost of road marking works. Because the structure of the equipment is very complex, the maintenance cost is high in the later stage. Before and after sales, long-term technical communication needs to be maintained, all of which limit the popularization and application of this advanced marking method.
