To ensure good visibility and long-lasting performance, manufacturers must select high-quality raw materials. Among them, titanium dioxide (TiO\u2082) is an important pigment used in white road marking paint to improve whiteness, opacity, and visual clarity. What is Titanium Dioxide? Titanium dioxide is a white inorganic pigment widely used in paints, coatings, plastics, and other industrial products. It is valued for its high refractive index, excellent hiding power, brightness, and chemical stability. In road marking paint, titanium dioxide helps produce a bright white finish and provides effective coverage over dark surfaces such as asphalt. It is available in two main forms: rutile and anatase. Rutile titanium dioxide is generally preferred for exterior road marking paint because of its higher refractive index and typically better weathering performance, especially when appropriately surface-treated.
