Performance comparison and applicable scenarios of two-component marking coatings and hot-melt coatings

In modern road marking engineering, two-component marking coatings and hot-melt marking coatings, as the two mainstream materials, each exhibit unique performance advantages. As a professional service provider in the field of road safety, Henan San Aisi Transportation Technology Co., Ltd., with over ten years of industry experience, provides in-depth analysis of the core differences between these two materials to help you make the optimal choice based on project needs.

1、 Comparative analysis of core performance
The durability performance of the two-component marking coating is achieved by chemically crosslinking and curing to form a three-dimensional network structure. Its wear resistance life can reach 5-8 years, making it particularly suitable for high-grade highways. Hot melt coatings rely on physical cooling to form, and are usually maintained for 2-3 years on roads frequently rolled by heavy vehicles, requiring regular maintenance.
The two-component marking coating with differential reflective performance adopts the “chemical anchoring” technology, with glass beads embedded at a more uniform depth and a reflectivity coefficient of over 350mcd. Hot melt coatings rely on “mechanical wrapping” to fix glass beads, with excellent initial reflectivity but a rapid decrease in wear coefficient.
The two-component marking coating with environmental adaptability can stably cure in environments ranging from -20 ℃ to 60 ℃, overcoming the limitations of winter construction of hot melt coatings. Its resistance to oil pollution and chemicals gives it significant advantages in special scenarios such as ports and airports.
The construction efficiency comparison of hot-melt marking paint has the characteristic of rapid curing in 5 minutes, which is particularly suitable for urban roads that require rapid opening of traffic. Two component coatings require a curing time of 40-60 minutes, but a single application can achieve a longer service life.

2、 Recommended Typical Application Scenarios

In terms of specific application scenarios, two-component marking coatings, with their excellent durability and environmental adaptability, have become the preferred solution for high standard scenarios such as highway mainlines and interchanges, airport runways and taxiways, and heavy-duty truck dedicated passages, especially suitable for special areas with chemical corrosion risks or extreme weather conditions.
In comparison, hot-melt marking coatings are more suitable for conventional road projects such as urban main roads, expressways, and ordinary national and provincial road markings due to their fast construction and moderate cost. At the same time, they show significant advantages in situations where high construction efficiency is required and durability is relatively low, such as parking lots, residential roads, and temporary traffic control markings. They are particularly suitable for budget constrained small and medium-sized projects.
These two types of marking paint materials have their own strengths, and when selecting them in practice, key factors such as project budget, traffic flow, environmental characteristics, and maintenance cycle need to be comprehensively considered to ensure the best performance price ratio and usage effect.
