Improve Visibility and Safety with Reflective Thermoplastic Paint for Road Markings
Product Description
What is Hot Melt Road Marking Paint?
Hot melt road marking paint, also known as thermoplastic road marking paint, is a durable, heat-applied coating used to create road markings such as lines, symbols, and signs on pavements. It is a solid, powder-based or block material that is melted at high temperatures (typically 180–200°C) and applied to road surfaces, where it cools and hardens to form a tough, reflective marking.
Composition:
-
Binders: Thermoplastic resins (e.g., hydrocarbon or alkyd-based) that provide adhesion and flexibility.
-
Pigments: For color (usually white or yellow) and visibility.
-
Glass Beads: Added for retroreflectivity, enhancing visibility at night.
-
Fillers: Such as calcium carbonate or silica for durability and cost-efficiency.
-
Additives: Improve flow, weather resistance, and curing.
Application Methods:
-
Screed: Extruded in precise shapes for structured markings.
-
Spray: Applied for faster, thinner lines.
-
Preformed: Pre-cut shapes melted onto the surface.
Key Features:
-
Durability: Resists wear, weathering, and traffic for 1–5 years, depending on conditions.
-
Reflectivity: Glass beads ensure high visibility in low-light conditions.
-
Quick Setting: Cools and sets within minutes, minimizing road closure time.
-
Thickness: Typically 1–3 mm, thicker than conventional paints.
Advantages:
-
Longer lifespan than solvent-based paints.
-
Environmentally friendly (low VOCs, no solvents).
-
High skid resistance for safety.
Limitations:
-
Requires specialized equipment for melting and application.
-
Higher initial cost than traditional paints.
-
Sensitive to improper surface preparation (e.g., moisture or dirt).
Uses:
-
Highways, urban roads, parking lots, airports, and pedestrian crossings.
-
Common in regions with heavy traffic or harsh weather due to its durability.
Hot melt road marking paint is widely used globally for its longevity, safety features, and cost-effectiveness over time.

Steps to Use Thermoplastic Road Marking Paint
-
Prepare the Road Surface
-
Ensure the road is clean, dry, and free of debris, loose material, or oil. A well-prepared surface is crucial for proper adhesion.
-
Heat the Paint
-
Start with thermoplastic paint in solid form (pellets or blocks).
-
Melt it in a specialized melter or pre-heater to approximately 200°C (392°F). The temperature must be controlled to keep the paint fluid without degrading it.
-
Apply the Paint
-
Add Glass Beads
-
Allow Cooling
