C5 hydrocarbon resin is widely used for thermoplastic road marking paint due to its competitive price and good performance. C5 hydrocarbonresin has better adhesion to the concrete and asphalt pavement, also has goodabrasion resistance and water resistance.Furthermore,C5 hydrocarbon resin has better affinity with inorganic materials, easy coating, good weatherresistance, fast drying and high firmness.C5 hydrocarbon resin can not only improve the physical properties, such as hardness, impact strength and bending,but also improve the UV and weather resistance and make thermoplastic roadmarking paint’s service life last 3 years.
