Low-temperature waterborne pavement marking paints: A road assessment of this LOW-VOC option

Significant advancements made in developing new polymer binder technology technology during 1990s, led to the introduction of waterborne traffic paints. One of the key elements of the advancement in the performance of waterborne paints , was a pH-triggered quick set of the binder. These latex binders neutralized with a strong base that exhibits high volatility, such as ammonium hydroxide, supplied at a high pH OF 10. The ammonia vaporizes, reducing the paint's pH, after it is applied. This process causes the paint to set up so that the film retains its integrity. The waterborne traffic have paints lower volatile organic compounds (VOC), are less toxic, and safer. They also provide better performance in comparison with solvent-based paints.
