Hot-Applied Thermoplastic Paint Fast and Easy Application for
Durable Road Markings
Product
Description
Thermoplastic road marking paint, also known as hot melt marking paint, is a widely used material for creating durable, high-visibility road markings. Below is a concise overview based on available information: Composition Synthetic Resin: Provides thermoplasticity, enabling fast drying and strong
adhesion to road surfaces. Non-polymeric resins, like colophony,
are also used. Glass Beads: Added for retro-reflectivity, improving visibility at night by
reflecting vehicle headlights. Bead sizes typically range from
0.1-1.4 mm. Pigments: Common colors are white (using titanium dioxide for UV
resistance) and yellow (organic pigments like Pigment Yellow 65,
74, or 83). Other colors are available for specific applications. Fillers: Fine fillers (e.g., calcium carbonate) and coarse fillers (e.g.,
sand) enhance mechanical strength, wear resistance, and surface
texture. Additives: Improve plasticity, resistance to subsidence, pollution, and
color fading. Anti-skid aggregates can be added for better
traction.
Application Methods Hot-Applied: Powdered thermoplastic is heated to ~200°C (392°F) in a kettle
and applied via spray, screed, or extrusion for road markings. Preformed Thermoplastic: Pre-cut shapes (e.g., arrows, letters) are heated with a torch or
heat gun and bonded to surfaces, ideal for symbols or small areas. Liquid Thermoplastic: Cold-applied, waterborne versions are sprayed for easier
application, though less common. Surface Prep: Surfaces must be clean, dry, and sometimes primed (e.g., for
concrete or old asphalt) to ensure adhesion.
Key Advantages for Applications Durability: Lasts 4-10 times longer than traditional paints, reducing
maintenance costs. Reflectivity: Glass beads enhance night and wet-weather visibility. Anti-Skid: Additives improve traction, critical for pedestrian and vehicle
safety. Fast-Drying: Sets in minutes, ideal for high-traffic areas. Eco-Friendly Options: Low-VOC or recyclable formulations available.
