Selection guide for highway marking coatings: Which is more suitable, hot-melt road coating or two-component coating?

The selection of marking coatings in highway construction and maintenance projects directly affects road safety performance and service life. As a leading enterprise in the domestic road marking industry, Henan San Aisi Transportation Technology Co., Ltd., with 30 years of technical accumulation and rich project experience, deeply analyzes the characteristic differences between hot-melt and two-component marking coatings to help you make the best choice.

1、 Analysis of Characteristics of Hot Melt Marking Coating

Outstanding economy: Low cost per unit area, suitable for large-scale applications

Convenient construction: mature technology, high popularity of equipment, fast construction speed

Good initial reflection: stable embedding effect of glass beads, strong visibility at night

Strong weather resistance: adaptable to various climatic conditions, universal in all regions

Applicable scenarios

Main roads with high traffic volume and ordinary road sections

Large scale marking projects with limited budget

Emergency maintenance projects that require rapid construction

Highway marking paint, marking paint

2、 Analysis of Characteristics of Two Component Marking Coatings

Super durability: chemically cross-linked and cured, with a service life of 2-3 times that of hot-melt coatings

Excellent adhesion: Especially suitable for new and old asphalt pavements, with excellent anti stripping performance

Good environmental performance: low VOC emissions, in line with green construction requirements

Good reflection on rainy nights: The surface structure is conducive to reflection on rainy days, enhancing safety in adverse weather conditions

Applicable scenarios

Special road sections such as tunnels and bridges

Key areas of high-grade highways

Engineering projects with strict environmental requirements

Road sections that require long-term maintenance free service

Highway marking paint, marking paint

3、 Key elements of selection decision

Engineering budget considerations:

Hot melt type has low initial investment and is suitable for budget controlled projects

Dual component full lifecycle cost is better, suitable for long-term operation on road sections

Traffic flow analysis:

Priority should be given to two-component materials with better wear resistance in high traffic sections

Hot melt type is sufficient to meet the demand on medium flow road sections

Environmental factor assessment:

Prioritize the dual component rain night reflective performance in rainy areas

Attention should be paid to the thermal expansion and contraction characteristics of materials in areas with large temperature differences

Construction condition evaluation:

Projects with tight construction schedules are more suitable for fast and efficient hot melt construction

Selecting two-component materials for projects with environmental protection requirements

4、 Professional construction suggestions

Base treatment: Regardless of the type of coating chosen, thorough road cleaning is crucial

Environmental control: Avoid extreme weather conditions during construction to ensure that material properties are fully utilized

Process selection: Hot melt type, pay attention to temperature control, dual component ensures precise proportioning

Quality acceptance: Focus on the reflectivity coefficient and adhesion strength indicators
