Abrasion of two-component thick paint marking lines

When the road surface is relatively rough and has a deep structure, it is suitable to use the two-component sprayed reflective road marking line.

The two-component marking line is commonly called acrylic after the pure resin curing reaction is complete because it is a reaction curing film.Acrylic is an important plastic polymer material that was developed earlier. Due to its special chemical structure, the marking coating film formed has high hardness and high wear resistance of the marking line. It is difficult to grind the pre-mixed glass beads out. Even if the inner mixed beads are ground out, the reflective performance will be basically lost. Please see the picture below:

(Note: high refractive index ≠ wear resistance, corrosion resistance, but high refractive index, wear resistance is relatively high)

As a result, after a few years of use of the two-component thick coating marking line, the reflective performance will be reduced. At this time, marking maintenance is required - removing the line and re-drawing or spraying to cover other reflective marking lines.

It is recommended that the thickness of the marking line is not less than 1.2mm, and the amount of paint per square meter is about 2 kg. The thickness of the coating formed in this way can effectively cover the road surface and sprinkle glass beads on the cladding surface, prolonging the service life of the marking line.
