These differences allow manufacturers to evaluate resin options according to their production process, application environment, and formulation design.
Acid Value and Resin FunctioRoad marking materials must maintain reliable performance under changing outdoor conditions, including temperature variations, vehicle traffic, and long-term exposure. In thermoplastic road marking formulations, resin selection plays an important role in controlling adhesion, drying behavior, flow characteristics, and durability. KOMO will showcase its rosin-based resin solutions at CHINACOAT 2026, Booth 5.2 C47, providing opportunities to discuss material selection with industry professionals.
As a pine chemical resin supplier, KOMO develops rosin-based materials for industrial applications, including road marking formulations. Its product range includes Road marking resin designed for hot melt road marking paint systems, helping manufacturers evaluate suitable resin components based on formulation requirements.
Understanding the Role of Thermoplastic Road Marking Resin
Thermoplastic road marking materials are widely used for traffic lines, symbols, and other road guidance applications. These systems generally require resin components that can provide suitable bonding, processing characteristics, and resistance to outdoor conditions.
Rosin is a natural and renewable resource that has been widely used as an industrial raw material. Through chemical modification of active groups such as carboxyl groups and conjugated double bonds, rosin can be converted into various deep-processed resin materials with adjusted properties for different applications.
Modified rosin materials have applications across multiple industries, including adhesives, coatings, inks, and electronic materials. In road marking systems, these resin materials can be selected as functional binders that influence the interaction between pigments, fillers, and other formulation components.
How Road Marking Resin Influences Thermoplastic Paint Performance
A road marking resin acts as an important binder component in thermoplastic road marking formulations. It helps determine how the coating melts, flows, adheres, and forms a solid marking layer after application.
Different resin characteristics can influence practical application performance. For example, resin selection may affect:
1.adhesion to asphalt or concrete surfaces;
2.melting and flow behavior during application;
3.drying and solidification speed;
4.resistance to heat, weather, and mechanical impact.
KOMO’s rosin resin series for hot melt road marking paints is designed for evaluation in thermoplastic road marking systems. These materials are described as supporting properties such as fast drying, good leveling, impact resistance, heat resistance, weather durability, yellowing resistance, and adhesion to road surfaces.
Adhesion and Surface Interaction
Road surfaces can vary depending on material composition, environmental exposure, and maintenance conditions. Therefore, resin selection is an important consideration when developing marking formulations with suitable surface adhesion.
A resin binder needs to work together with other components, including pigments, fillers, and additives. The balance between resin chemistry and the complete formulation determines how the finished marking material performs under practical application conditions.
Flow Behavior and Application Efficiency
Thermoplastic road marking materials are heated before application. During this process, resin properties influence melting behavior, viscosity, and leveling characteristics.
A suitable resin can help formulators adjust processing conditions according to equipment requirements and application methods. Factors such as melt viscosity and softening point are commonly evaluated when selecting resin materials for thermoplastic systems.
Key Factors When Selecting Road Marking Resin
Softening Point and Processing Requirements
Softening point is an important technical parameter for thermoplastic road marking resin because it relates to melting characteristics and application behavior.
KOMO provides different rosin resin options with varying softening points and viscosity characteristics. According to the product specification chart, typical products in this series show softening points ranging from approximately 97°C to 112°C, depending on the resin grade.
nality
Acid value is another parameter considered during resin selection. It provides information about resin functionality and can influence interactions with other formulation ingredients.
For KOMO’s road marking resin series, typical acid values vary by product type. The specification chart lists values ranging from ≤13 mg/g to 45 mg/g among different grades, allowing formulators to compare materials according to application requirements.
Color Stability and Outdoor Performance
Road markings are exposed to sunlight, weather changes, and environmental contaminants. Resin characteristics such as color stability and resistance to aging are therefore important considerations.
Light-colored resin materials can help manufacturers evaluate appearance requirements in thermoplastic marking systems. KOMO’s road marking resin products are described as light-colored and low-odor materials with resistance characteristics suitable for road marking applications.
