Two Component MMA Road Marking Paints
Structure and Reaction
Two-component road marking paints are typically based on reactive methyl methacrylate (MMA) and are mixed with an initiator, benzoyl peroxide (BPO), at the time of application. This mixture triggers a rapid chemical reaction, causing the paint to harden and adhere firmly to the surface. These paints offer extremely high physical and chemical resistance.
The term drop-on refers to the application of glass beads immediately after the paint is applied while it is still wet. These beads embed into the surface as the paint cures, enhancing the retroreflective properties of the road markings.
Core Properties &
Reflective Performance
MMA-based road marking paints are engineered to withstand harsh weather conditions and heavy abrasion. Their high UV resistance ensures long-term color stability, while their mechanical and chemical durability is exceptional. They offer excellent adhesion and wear resistance.
Once the components are mixed, the reaction starts quickly, resulting in a fast drying time that allows roads to reopen to traffic shortly after application. When combined with drop-on glass beads, these paints significantly enhance night-time visibility, contributing to safer driving conditions.
Application Areas &
Available Techniques
These two-component MMA paints are ideal for high-traffic and high-durability marking areas such as pedestrian crossings, speed bumps, signalized intersections, parking areas, and warning zones. They are also suitable for critical infrastructure like main junctions and road seams.
Application methods include screed, structured (sprinkle), profiled, or spray techniques (including three-component variants), as well as manual tools. Drop-on glass beads are applied immediately after the paint is laid. A variety of professional application machines are available, including hydraulic proportioners and 98:2 ratio spray systems designed for MMA.
