Difference between one-component and two-component road marking paint
Difference between one-component and two-component road marking paint There are one-component paint and two-component paint for road marking. One-component paint is usually ready-to-use, and it can be film-dried by evaporation of solvents or by direct reaction with certain substances in the air, such as moisture. On the contrary, the two-component paint is generally used by mixing A and B in a certain proportion. It is cured by a reaction between the two materials, then a certain thickness of film is formed in the base plane. The two type paints are easily confused. For the one-component paint, put the high solid content paint (the resin is also pre-polymerized) into two barrels, then add initiator (or curing agent), and use two-component equipment for construction.The spray thickness can be reach 600-800μm, drop the reflective glass beads on the paint surface is also available. Moreover, it is very close to the smell of two-component paint. But there are some differences in their lift time and reflective properties. Therefore, when purchasing two-component road marking paint, you could ask for the product technical data sheet to avoid loss. Tory has developed a two-component road marking paint with superior adhesion and surface strength based on the characteristics of MMA resin. If you have the same demand on two-component paint development, you could view its detailed technical parameters via the link provided below: https://www.cntory.com/2-components-paint-mma-resin_p31.html
Abrasion and maintenance of Two-Component road marking lines
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: Above: Corrosion and wear on the surface of reflective glass beads RI1.5 on the left, RI1.9 in the middle, and long-life wear-resistant glass beads on the right (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.
