Hot melt paint, also known as thermoplastic road marking paint, is a type of coating used primarily for road markings, applied in a molten state after being heated. It falls under standards like BS3262 for hot-applied thermoplastic materials and is designed for durability, reflectivity, and quick setting. Unlike cold-applied paints, it requires heating to become fluid, then solidifies rapidly upon cooling.

Key Features:

Composition (per BS3262):
- Binder (18–25%): Resins (e.g., C5 petroleum or rosin-based) for adhesion and flexibility.
- Glass Beads (≥20%): For retro-reflectivity, enhancing night visibility.
- Pigments (5–12%): Titanium dioxide (white) or organic pigments (yellow) for color.
- Fillers (40–50%): Calcium carbonate or silica for bulk and skid resistance.
- Additives (1–5%): Plasticizers and stabilizers for flow and durability.
Application:
- Heated to 180–220°C in a pre-heater or applicator.
- Applied via screeding (2.5–3 mm), spraying (1.5–2 mm), extrusion (3–6 mm), or manual methods.
- Drop-on glass beads added (250–400 g/m²) for reflectivity.
Setting: Solidifies in 2–5 minutes, allowing quick road reopening.
Properties:
- Durable against traffic, UV, and weather.
- Skid-resistant (SRV ≥45).
- Reflective (≥100 mcd/m²/lx for white per BS3262-2).

Uses:

Road markings: Lane lines, pedestrian crossings, arrows, bike lanes.
Airports: Runway and taxiway markings.
Parking lots and industrial floors: Safety and directional markings.

Advantages:

Long-lasting compared to solvent-based paints.
Rapid curing minimizes traffic disruption.
High visibility and safety compliance.
