There are mainly the following types of coatings for highway markings: solvent-based coatings, heating coatings, hot-melt coatings (also called melt-type coatings), two-component coatings, water-based coatings and other types.
Some road marking paint formulas
1. Normal temperature solvent type
Extension pigment 35-45%
