MMA high-light road marking paint
Product Introduction
MMA high-light road marking paint forms a polymer coating film through cross-linking reaction. Changda Company first proposed the concept of high-brightness marking line in China, and promoted the use of such marking lines on high-grade highways nationwide. The effect is constantly adjusted to achieve a strong adhesion of the coating to the glass beads, achieving "anchoring" of the glass beads, so that the marking has a continuous high reflective performance.
Specification
◆ High reflection: Improve the adhesion of paint and glass beads by optimizing the formula to achieve continuous high reflection
◆ High wear resistance: high polymer polymer marking film 0.6mm thickness and hot melt marking 2mm thickness wear resistance
◆ Rapid construction efficiency: Through the adjustment of paint formulation and improvement of the process, vehicle construction can be adopted. No need to get off the vehicle during the whole operation process, no workers on the road surface, ensure the safety of construction workers; fast, safe, high-light, daily line Amount of 15000m2, minimizing the closing time and improving road capacity

◆ Application recommendation:
New pavement: a section that requires a high anti-cursor line;
Quickly restore the reflective pavement: “One spray is bright” for rapid maintenance. The old hot melt marking line can not meet the standard requirements and can be directly on it.
Spray a layer of high-bright marking paint to restore the reflective performance;
High-altitude areas: Tibet, Qinghai, Xinjiang, Sichuan and other places with an altitude of ≥4000m.
