Research and development of polyurea pavement marking paint

Abstract

Pavement markings make an important contribution to the safety of people and vehicles on roads. Many types of pavement marking materials have been used, and most recently, polyurea materials have been used as a binder in pavement marking paint. This type of paint has high retro-reflection and durability, so it has been widely applied for use at airports and on highways around the world. This article introduces the results of our research and the making of polyurea pavement marking paint using the formula: binder/harder ratio (1.3/1 by weight), 42% of pigment and filler, 10% of reflective balls, rheological additive, and dispersive additive to create outstanding features (retro-reflection > 260 mcd/m2/lux).
