Analysis of Characteristics and Application of Waterborne Road Marking Paint

Road markings are one of the essential safety features of modern roadways. All of the horizontal road markings systems consist of a pigmented coating containing partially embedded retroreflective elements such as glass beads. In addition to durability and functionality of the road marking, ease of application and their effect on human health and environment are also primary considerations. Road markings can be divided into plural component systems that cure due to chemical reaction that occurs at the site of application, thermoplastics that require heat for application, and paints. The first two systems shall not be extensively discussed herein. Traffic paints can be separated into solventborne and waterborne materials. Over 100 years old solventborne technology includes paints based on alkyd, alkyd-acrylic, styrene acrylics, and lately also 100% acrylic resins — all of these paints afford consistent application properties, are easy to dilute to the desired application viscosity, and provide quite reasonable "no track" time under a variety of conditions such as lower temperatures and high humidity. Their environmental and human health impact is significant. Modern waterborne paints are based on a 100% acrylic technology and incorporate developed in the 1990s quick-set chemical mechanism for drying. In most cases, properly formulated and applied waterborne paints provide advantages as compared to other road marking materials — ease of application without the need to dilute or stir, unparalleled safety during manufacturing, transport, and use, and exceptional durability together with very good adhesion of glass beads. Their drawback is slow development of washout resistance, particularly during application at high humidity and low temperature. Waterborne road marking paints are extensively and successfully used in North America and in Europe in Scandinavia and also in France, Italy, Spain, and some areas in Germany. Impact of waterborne traffic paints on human health and our environment is very significantly reduced as compared to solvent-based materials. Analysis of characteristics of waterborne road marking paints and their application shall be presented in comparison with solventborne paints. Based on the comparison and results from test application on the road, intelligent decisions regarding future use and function of waterborne road marking paints shall be possible.
