There are problems such as performance and air pollution during construction. Also,
The drying time at 20 ° C. at the time of construction is 5 to 6 minutes for heating for heating to about 60 ° C. and 10 for heating at room temperature.
It takes ~ 15 minutes. Moreover, since the film thickness is small, there is a problem in durability.

Viscosity at the temperature at the time of construction is 100-1000mPa.
s is a method for applying road marking, characterized in that the coating material for road marking of s is applied so that the film thickness is in the range of 0.4 to 0.9 mm. If the viscosity at the time of construction is less than 100 mPa · s, the drying property, the compressive strength, the stain resistance, and the like deteriorate.
Further, when the viscosity at the time of application exceeds 1000 mPa · s, the finish of the coating film surface after application deteriorates. From such a viewpoint, the viscosity at the time of construction is more preferably from 300 to 1000 mPa · s, and most preferably from 500 to 800 mPa · s. The thickness of the road marking is set at 0. 0 to maintain the sliding frictional resistance of the road surface properly and to provide durability.
4 to 0.9 mm. The reason for this is that when the film thickness is small, the road surface unevenness appears on the coating film surface, so that the sliding friction resistance increases, but on the other hand, the durability decreases. 0.6-0.8 from the balance between sliding friction resistance and durability
mm is particularly preferable.
