Waterborne acrylic pavement marking paints have advantages over solvent-based marking paints for the health of users and the environment as well as for maintaining visibility at night for the safety of the driving public. Waterborne paints have been the markings of choice for delineating roads, parking lots and airfields in the USA, Australia, Brazil and parts of Europe and Asia since the mid to late 1990s and use is growing in other regions of the world. The widespread use of waterborne pavement marking paints became practical with the quick set chemistry technological advance in 1990. This technology enabled the commercialisation of a generation of fast dry acrylic polymer binders that provide the early tracking and washout resistance needed for pavement marking applications. Further advances in polymer architecture have enabled: (1) Cost-effective high build waterborne alternatives to hot melt and two component durable markings; (2) Markings that provide day and night visibility on both dry and wet surfaces; and (3) Markings that can be applied at temperatures down to 2 deg C to extend the painting season. Advances in waterborne pavement markings promise to continue in the future with the development of pigment absorbing polymers and water absorbing drying adjuvants.
