Wholesale Yellow Hot Melt Thermoplastic Road Marking Paint for Highway Construction 

                                       Product Description                               

Hot melt marking paint, also known as thermoplastic road marking paint, is a type of powder paint used for road surface markings. When heated to approximately 200°C (392°F), it melts and is applied to road surfaces, where it quickly hardens upon cooling to form a durable, wear-resistant, and reflective layer.

Composition of Hot Melt Marking Paint:

• Synthetic Resins: These serve as binders, providing thermoplasticity and ensuring strong adhesion to the road surface. Common resins used include:

  • Aliphatic Hydrocarbon Resins: Derived from petroleum, these resins offer excellent color stability and resistance to UV degradation.
  • C5 Petroleum Resins: These are widely used due to their good compatibility with other ingredients and their ability to enhance the paint's adhesive properties.

• Pigments: Provide color and opacity to the markings.

  • Titanium Dioxide (TiO₂): Used for white markings, it offers high brightness and opacity.
  • Organic Pigments: Such as Pigment Yellow 65, 74, or 83, are used for yellow markings.

• Glass Beads: Incorporated to enhance reflectivity, improving nighttime visibility. These beads are typically colorless and transparent, reflecting light from vehicle headlights back toward the driver.

• Fillers: Materials like calcium carbonate and silica sand are added to improve mechanical strength, wear resistance, and to adjust the paint's viscosity.

• Additives: Substances such as plasticizers, anti-settling agents, and stabilizers are included to enhance flexibility, prevent sedimentation, and improve overall durability of the paint.
