Fast Delivery Strong adhesion high reflective white yellow thermoplastic Road Line Marking Paint

Description of Thermoplastic Road Line Paint

1. Material Composition
Resin Type and Quality: High-quality thermoplastic resins, such as hydrocarbon or maleic resins, provide better binding properties and durability.
Pigments: Stable and durable pigments (e.g., titanium dioxide for white lines) ensure the coating maintains its color and integrity over time.
Glass Beads: Glass beads not only improve reflectivity but also affect wear resistance. Properly embedded beads enhance durability, while poorly embedded beads can increase wear.
Fillers: The type and proportion of fillers (e.g., calcium carbonate) impact the mechanical strength and abrasion resistance.

2. Application Thickness
Thickness of the Coating Layer: A properly applied layer (typically 1.5-2.5 mm for road markings) ensures sufficient material to resist wear. Thinner layers wear out faster under traffic.

3. Road Surface Compatibility
Surface Type: Adhesion is better on smooth, well-prepared surfaces (like asphalt) than on rough or porous surfaces, which can accelerate wear.
Surface Preparation: Improperly cleaned or primed surfaces can lead to poor bonding and quicker wear.

4. Traffic Conditions
Traffic Volume and Weight: Roads with heavy traffic or high loads (e.g., trucks) subject coatings to increased abrasion, leading to faster wear.
Vehicle Speeds: Higher speeds generate more friction and heat, which can degrade the coating faster.

5. Environmental Factors
Temperature Variations: Extreme heat or cold can cause thermal expansion or contraction, leading to cracking or flaking of the coating.
Rain and Moisture: Prolonged exposure to water can weaken the bond between the coating and the road surface.
UV Radiation: Prolonged sun exposure can degrade the resin and pigments, reducing wear resistance.

6. Application Process
Heating Temperature: Proper heating (180°C-220°C) ensures the coating melts uniformly and bonds well to the surface. Overheating or underheating can compromise adhesion and durability.
Mixing Uniformity: Uneven distribution of components (resin, glass beads, fillers) during application can result in weak spots that wear out faster.
Curing Time: Allowing the coating to cure adequately ensures it reaches its optimal hardness and wear resistance.

7. Glass Bead Quality and Embedding
Bead Hardness: Harder beads provide better resistance to abrasion and longer-lasting retro-reflectivity.
Bead Coverage: Evenly distributed beads that are embedded at the right depth (~50% into the coating) balance reflectivity and durability.

8. Maintenance Practices
Cleaning: Regular cleaning of road surfaces prevents dirt and debris from accelerating wear on the coating.
Repairs: Timely patching of damaged or worn sections prevents further degradation.

9. Compliance with Standards
Testing and Certification: Coatings manufactured and applied according to recognized standards (e.g., BS 3262 or ASTM) often exhibit better wear resistance because they meet stringent quality requirements.

Detailed Process of Thermoplastic Paint Construction

1. Prepare the Surface

• Cleaning: Ensure the surface is free of dirt, grease, oil, dust, and loose debris.
• Repair: Fix cracks or uneven areas to create a smooth surface.
• Drying: The surface must be dry to ensure proper adhesion

2. Mark the Layout

• Use chalk, tapes, or temporary markers to outline the areas to be painted (lines, symbols, or shapes).
• Verify measurements against specifications or local standards.

3. Heat the Thermoplastic Paint

• Use a melting kettle or thermoplastic preheater to melt the paint.
• Heat to the recommended temperature, typically 180–220°C (356–428°F).
• Avoid overheating, as it may degrade the paint and affect quality.
• Stir continuously to ensure uniform consistency.

4. Primer Application (if required)

• Apply a primer to the surface if recommended by the manufacturer.
• This is especially needed for non-porous surfaces like concrete or asphalt.
• Allow the primer to dry before applying the paint.

5. Apply the Paint

• Screed Method: Use a screed box to create uniform thickness for road markings.
• Spray Method: Use a spray machine for even application on large or irregular areas.
• Extrusion Method: For thicker, raised markings.
• Hand Application: For small areas or repairs, manually pour and spread the molten paint.
• Preformed Thermoplastic: Lay pre-cut sheets or symbols on the surface and heat with a propane torch until adhered.

6. Check and Correct

After the coating is completed, check and correct the line shape, check the spread of glass beads, etc.

After confirming that it is correct, the construction site will be cleaned up.

After the line is dried and hardened, the relevant construction equipment can be transferred, the safety facilities can be dismantled, and the traffic can be opened.

Advantages of Thermoplastic Paint

- High Durability
It has excellent abrasion - resistance and can withstand repeated friction and pressure from vehicles and pedestrians. It can maintain a good appearance for a long time even in areas with heavy traffic. For example, on the lane markings of a highway, it's not easy to wear out even after a large number of vehicles have passed over it.
- Quick - drying
It dries fast and can be put into use shortly after application. This is very important in road construction as it can reduce the impact on traffic.

What Are The Application Of Thermoplastic Paint

Hot melt paint is mainly applied in the following fields:

Transportation Field

- Road Marking: This is the most important application of hot - melt paint. For example, in expressways, urban roads, parking lots and other places, hot - melt paint is used to draw traffic markings such as lane lines, crosswalks, stop lines and directional arrows. Because it dries quickly and the road can be open to traffic in a short time. Moreover, it is wear - resistant and pressure - resistant and can withstand the frequent passage of vehicles and various weather changes.

Industrial Field

- Equipment Marking: In factory workshops, it is used to mark various machinery and equipment. For example, in the dangerous parts of large - scale machinery, around operation buttons, and the direction of pipelines, clear markings are made with hot - melt paint to play a role of warning and guiding operation.

Architectural Field

- Floor Marking: In the public areas of buildings, such as shopping malls, supermarkets, hospitals, schools and other places, hot - melt paint is used to divide different functional areas, such as shopping aisles, safety passages, queuing areas, etc. It is not only eye - catching but also durable.
