Durable Thermoplastic Powder Coating for Heavy Traffic and Harsh Weather Resistance
Product Description
Thermoplastic hot melt paint, also known as hot melt marking paint, is a type of powder coating primarily used for road surface markings. It’s composed of synthetic or non-polymeric resins, glass beads, pigments, and fillers like calcium carbonate or sand. The paint is heated to around 200°C (392°F) in a hot melt kettle, turning it into a liquid that can be sprayed or applied onto roads. Upon cooling, it forms a thick, durable polymer layer that’s wear-resistant, bright, and reflective.
Key characteristics:
-
Durability: Resists heavy traffic and harsh weather, lasting longer than traditional paints.
-
Reflectivity: Often includes glass beads to enhance visibility at night by reflecting vehicle headlights.
-
Application: Requires specialized equipment to heat and apply, typically drying quickly to minimize traffic disruption.
-
Anti-skid: Can incorporate coarse fillers to improve traction, though some formulations may need additives to prevent slipperiness in wet conditions.
It’s widely used for road lines, pedestrian walkways, and anti-skid areas due to its longevity and visibility, though it may be costlier upfront compared to solvent-based paints.
Uses:
-
Road markings: Lane lines, pedestrian crossings, arrows, bike lanes.
-
Airports: Runway and taxiway markings.
-
Parking lots and industrial floors: Safety and directional markings.
How to Apply Thermoplastic Paint:
-
Prepare Surface: Clean road to remove dirt and debris; ensure it’s dry. New asphalt needs 14-30 days to cure; concrete may need primer.
-
Heat Paint: Melt thermoplastic powder in a kettle at 180-200°C, stirring until liquid.
-
Mark Layout: Outline lines with chalk or templates per regulations.
-
Apply:
-
Screed: Use a screed box for 1-3 mm thick lines.
-
Spray: Use a spray machine for 0.5-1.5 mm layers on large areas.
-
Sprinkle glass beads immediately for reflectivity.
-
Cool & Inspect: Let cool 5-15 minutes; check thickness, adhesion, and reflectivity.
-
Clean Up: Remove excess material; clean equipment.
Tips: Work above 5°C, avoid wet conditions. Wear protective gear and follow manufacturer guidelines.
