Filler hiding power is very low, and its main role is to increase the coating volume, improve wear resistance and durability of the coating. The fillers generally inexpensive, and help to reduce the cost of the paint. Thus in addition to choose the rutile-type titanium dioxide as a white pigment, in the test process to select a light calcium carbonate, heavy calcium carbonate, talc, wollastonite powder, precipitated barium sulfate, barite powder with a variety of filler tested.
The drying time of the coating, the solvent coatings play an important role. Solvent suitable road marking paint should have a faster rate of evaporation, low toxicity, low cost. All volatile solvents in the construction into the atmosphere, will cause some air pollution, therefore, should try to reduce their usage. The coatings are generally used mixed solvent. Mixed solvent including the solvent and diluent, in the base material has sufficient ability to dissolve under the premise, the greater the amount of diluent, the more able to reduce the price of the coating. The drying time is the most important performance requirements of traffic marking material. Thus, the choice of solvent in addition to the above conditions, the more important is the rate of evaporation of the solvent. Based on these selection criteria to select a ketone solvent (cyclohexanone, acetone), ester solvents (ethyl acetate, butyl acetate), and a hydrocarbon solvent (xylene, toluene). These solvents with the use, and to meet the requirements of the mixed solvent can be obtained by experiment.
