Le dioxyde de titane de type rutile est g\u00e9n\u00e9ralement privil\u00e9gi\u00e9 pour les peintures de marquage routier en ext\u00e9rieur en raison de son indice de r\u00e9fraction plus \u00e9lev\u00e9 et de sa meilleure r\u00e9sistance aux intemp\u00e9ries, notamment lorsqu'il b\u00e9n\u00e9ficie d'un traitement de surface adapt\u00e9.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Key_Benefits_of_Titanium_Dioxide_in_Road_Marking_Paint\"><\/span>Principaux avantages du dioxyde de titane dans les peintures de marquage routier<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"1_Improving_Whiteness_and_Brightness\"><\/span>1.

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.
