Product Description
Thermoplastic paint is a type of thermoplastic coating material widely used for road and pavement markings. It is characterized by its ability to melt and flow when heated and then solidify quickly as it cools. This paint is formulated with synthetic resins, pigments, fillers, and additives to provide durability, weather resistance, and reflective properties.
Hot melt paint is preferred for applications requiring high performance and longevity, especially in areas subject to heavy wear and tear.
Detailed Process of Thermoplastic Paint Construction
1. Surface Preparation
Cleaning: Ensure the surface is clean and free of dust, grease,
oil, and other contaminants. This improves adhesion.
Drying: The surface must be completely dry. Moisture can reduce the
bond strength of the paint.
Repair: Any cracks or holes in the surface should be repaired to
create a smooth base.
2. Marking Layout
Preliminary Marking: Use chalk or temporary markers to outline
where the hot melt paint will be applied.
Measurement: Ensure that lines, symbols, or patterns meet design
specifications and local standards.
3. Equipment Preparation
Melting Kettle: Heat the hot melt paint in a specialized melting
kettle. Temperatures typically range between 180–220°C (356–428°F).
Mixing: Stir continuously to ensure uniform melting and prevent
scorching.
Application Machine: Load the molten paint into a road marking
machine equipped with an applicator for precise dispensing.
4. Application
Primer Application (if required): Some surfaces require a primer to
improve adhesion.
Dispensing: Apply the molten paint using a road marking machine.
The machine ensures even thickness and width according to
standards.Thickness: Commonly 1.5–2.5 mm for road lines.
Width: Adjusted as per specifications (e.g., 10 cm for standard
road lines).
Glass Beads (Optional): While the paint is still hot, apply
reflective glass beads for nighttime visibility. These can be
dispensed automatically or manually.
5. Drying and Curing
Rapid Cooling: Hot melt paint sets quickly, usually within a few
minutes, as it cools.
Inspection: Check the line for uniformity, proper adhesion, and
adherence to specifications.
6. Clean-up and Maintenance
Equipment Cleaning: Clean the kettle, applicator, and other tools
immediately to prevent hardened paint from clogging them.
Touch-ups: Repair any gaps or imperfections in the marking.
Safety Tips
Use protective gear, including gloves and heat-resistant clothing,
as the paint is applied at very high temperatures.
Ensure proper ventilation to avoid inhalation of fumes.
Adhere to traffic control measures if working on active roads.
