High-Index Reflective Thermoplastic Road Marking Paint Powder Coating with Glass Beads Mainly Resin Product
Product Description
Thermoplastic paint is a type of durable, heat-applied coating commonly used for road markings, traffic signs, and other outdoor applications. It’s made from a mixture of synthetic resins, pigments, glass beads (for reflectivity), and fillers that solidify when cooled after being heated to a molten state. Unlike regular paint, which dries through solvent evaporation, thermoplastic paint is applied in a hot, liquid form (typically at temperatures between 180°C and 220°C or 356°F to 428°F) and hardens as it cools, forming a thick, tough layer that bonds well to surfaces like asphalt or concrete.
It’s popular for its longevity, weather resistance, and ability to withstand heavy traffic. The glass beads embedded in it enhance visibility at night by reflecting light from vehicle headlights. You’ll see it in things like lane lines, crosswalks, or parking lot markings. There are two main types: hydrocarbon-based (derived from petroleum) and alkyd-based (made from natural oils), with the former being more common due to cost and performance.

Steps to Use Thermoplastic Paint:
-
Surface Preparation:
-
Clean the surface thoroughly to remove dirt, dust, oil, or loose debris. Use a broom, wire brush, or pressure washer as needed.
-
Ensure the surface is dry, as moisture can prevent proper adhesion.
-
For porous surfaces like concrete, you may need to apply a primer to enhance bonding. Check the manufacturer’s instructions.
-
Heat the Thermoplastic:
-
Load the thermoplastic material into a preheater or melting kettle.
-
Heat it to the recommended temperature, typically between 180°C and 220°C (356°F to 428°F), depending on the specific product. Stir occasionally to ensure even melting and to avoid scorching.
-
Monitor the temperature carefully—overheating can degrade the material.
-
Test the Consistency:
-
The molten thermoplastic should have a smooth, liquid consistency, free of lumps. If it’s too thick, it won’t apply evenly; if too thin, it may not set properly.
-
Apply the Paint:
-
For Road Markings: Use a striping machine or screed box to pour the molten thermoplastic onto the surface in the desired pattern. Work quickly, as it begins to cool and harden once applied.
-
For Smaller Areas: Use a hand-held applicator or trowel to spread the material evenly.
-
Maintain a consistent thickness (usually 1.5–3 mm, depending on the project requirements).
-
Add Glass Beads (Optional):
-
For reflective markings (e.g., road lines), sprinkle glass beads over the wet thermoplastic immediately after application. The beads will embed as it cools, improving visibility.
