How to increase the spray thickness of 2-component MMA paint?
The two-component sprayed reflective road marking line is generally only used for the renewed of city roads, and the thickness is normally like 0.6-0.8mm (actually about 0.5mm). No matter how high is the strength of the paint, the thickness is not enough for roads with large traffic.
How to maximize the performance of the two-component sprayed reflective road marking line, to meet the project requirements, but also ensure the construction thickness and reduce the construction cost?
1. The amount of spray coating per square meter is 1.0~1.5 kg, and it is equipped with a double glass bead dispenser (or spray spreader).
2. The amount of glass beads drop on the surface is not less than 0.45 kg, and the amount of premix glass beads is not less than 0.5 kg (or 30% by weight of the paint)
3. Basic ratio: 1 square meter with 1 kg glass beads (there is some loss, the actual application is 0.85KG)
4. The particle size distribution of glass beads: about 0.4~1.0mm for drop on, and about 0.85-1.4mm for the intermix.
5. Thickness the road marking paint: ≥1.2mm
6. The retroreflectivity data is basically above 400mcd.
