Modified Alkyd vs. Thermoplastic Acrylic: Understanding the Difference in Solvent-Based Roadline Paint

Choosing the right solvent-based roadline paint in Malaysia is key to ensuring clear, long-lasting road markings that withstand the country’s hot, humid, and high-traffic conditions. One of the most important factors is the resin type, which determines how well the paint performs over time. The two most common options are modified alkyd resin and thermoplastic acrylic resin.

Modified Alkyd Resin

Modified alkyd resins provide smooth flow, good leveling, and strong adhesion to asphalt and concrete. With the addition of a catalyst, these resins can achieve faster drying, reducing road closure times compared to traditional alkyd paints. Once cured, they form a tough and flexible film suitable for low- to medium-traffic areas. However, under intense sunlight, alkyd-based coatings may experience faster color fading and lower UV resistance over time.

Thermoplastic Acrylic Resin (TPA)

Thermoplastic acrylic resins cure by solvent evaporation, allowing rapid drying and forming a hard, weather-resistant film. They offer excellent color stability, UV resistance, and chemical durability, making them ideal for highways, airports, and busy city roads. These resins help maintain bright, visible markings that resist wear and fading, even under heavy use and tropical weather.
