Non-Toxic and High-Performance Thermoplastic Paint for Sustainable Road Markings

Product Description

Thermoplastic paint is a type of paint composed mainly of thermoplastic resins, along with pigments, fillers, and additives. The thermoplastic resins are the key component. Common thermoplastic resins used include acrylics, polyvinyl chloride (PVC), and ethylene-vinyl acetate (EVA). Pigments give the paint its color, fillers can enhance properties like hardness and opacity, and additives may be used to improve aspects such as flowability, drying speed, and adhesion.

2. Working Principle

Thermoplastic paint operates based on the principle of thermoplasticity. When heated above a certain temperature (its melting point), the paint softens and becomes fluid, allowing it to be easily applied to a surface. Once applied, as it cools down, the thermoplastic components solidify, forming a durable and adherent coating. This process is reversible, meaning that upon reheating, the paint can be remelted and reprocessed if needed.

Features:

- Durability: It offers excellent abrasion resistance. The hardened paint film can withstand the friction from foot traffic, vehicle tires (in the case of road markings), and other mechanical stresses without wearing away quickly. For example, thermoplastic road markings can last for several years even with continuous exposure to heavy traffic.
- Weather Resistance: Thermoplastic paint is highly resistant to the effects of weathering. It can endure UV radiation, rain, snow, and temperature fluctuations without significant degradation. This makes it suitable for outdoor applications where long-term exposure to the elements is expected.
- Chemical Resistance: It has good resistance to a variety of chemicals, including common solvents, oils, and mild acids and alkalis. This property helps in protecting surfaces in industrial environments or areas where chemical spills may occur.
- High Visibility: When used for marking purposes, such as road markings or safety markings in industrial facilities, thermoplastic paint can be formulated to have high reflectivity. Reflective glass beads are often added to the paint during application, which significantly enhances visibility, especially at night or in low-light conditions.
