What are the highlights of two-component marking coatings compared to hot-melt marking coatings?

Two component marking paint is a road marking paint formulated with two sets of low viscosity active acrylic resins as film-forming agents. Before starting construction, a curing agent was added to component B and mixed evenly. The two components were mixed and applied to the road surface during the cross-linking feedback process, resulting in a durable film layer.

The two-component marking coating has special factors that protect its toughness and prevent simple cracking. Low molecular weight active aggregates have excellent permeability to the capillary pores of road surfaces before crosslinking and solidification. After fine penetration with cement concrete road surfaces, they produce anchoring efficiency, consolidate the adhesion of marking lines, and are not easily peeled off. The convergence feedback of the film-forming process generates a network of large molecular structures, which connect the various components of the coating into a dense and complete structure, with high hysteresis strength and wear resistance. After the two components converge and provide feedback, a new network of molecules is generated, which belongs to a super large molecular weight cross-linked network. The marked line has low-temperature connection cracks, high temperature does not soften, and there is almost no aging during use. Secondly, it has a good anti pollution instinct and is not easily contaminated with dust. Solvent free, environmentally friendly. Therefore, two-component marking coatings are the future trend of railway marking.
