The base material is mixed with the curing agent in proportion when used, and the paint film is dried by chemical cross-linking reaction to form a hard paint film, which has good adhesion to the ground and glass beads. It has the advantage of fast drying, wear resistance, water resistance, acid and alkali resistance, good weather resistance, and is suitable for various climatic conditions. It is widely used for cement pavement and asphalt pavement as long-term marking.
