Coatings, as essential materials for protection, decoration, and enhancing product value, rely heavily on their performance and appearance. However, various surface defects such as pinholes, orange peel, and ripples often occur during the coating application process. These issues not only affect aesthetics but also compromise the performance and longevity of the coating. Corechem's polyester leveling agents are here to help you perfectly resolve coating surface defects!
 

Unique Advantages of Polyester Leveling Agents

Compared to traditional silicone and polyacrylate leveling agents, Corechem's polyester leveling agents offer unique advantages:

• Enhanced Fullness: Polyester leveling agents significantly improve the fullness and three-dimensionality of the coating, giving it a more stacked and vibrant effect. This is because the molecular structure of polyester effectively fills the tiny pores on the coating surface, making the film denser and smoother.

• High Transparency and Gloss: Polyester leveling agents maintain high transparency and gloss of the coating, enhancing its visual appeal and making the product more attractive and upscale.

• Excellent Leveling Performance: Polyester leveling agents effectively reduce surface defects such as pinholes, orange peel, and ripples, resulting in a smoother and more even film. This improves the coating's weather resistance, corrosion resistance, and wear resistance.

• Easy Foam Elimination: Polyester leveling agents facilitate foam elimination, preventing coating defects caused by foam, thereby improving product yield and production efficiency.

• Molecular Structure Design: Corechem's polyester leveling agents feature a special molecular structure design that effectively reduces the surface tension of the coating system, enhancing the leveling properties of the film. The long-chain polyester structure helps form a uniform molecular arrangement in the coating, reducing film defects.

• Compatibility: Corechem's polyester leveling agents exhibit excellent compatibility with various resin systems, including alkyd resins, acrylic resins, and polyester resins, without causing flocculation or phase separation in the coating system.

• Temperature Resistance: Corechem's polyester leveling agents remain stable over a wide temperature range, delivering excellent leveling performance even in high-temperature baking coatings without affecting the final performance of the film.

• Anti-Cratering: The unique polyester structure helps prevent surface defects such as craters and fish eyes during the drying process, ensuring a smooth and uniform coating surface.

• Environmentally Friendly: Corechem's polyester leveling agents are produced using environmentally friendly processes, minimizing environmental impact and meeting the demand for green products in the coatings industry.

Performance Differences Between Types
To better select the appropriate leveling agent, it is essential to understand the performance differences among various types:

• Silicone Leveling Agents: Offer excellent leveling performance and substrate wettability, but are prone to foam generation and may negatively impact interlayer adhesion.

• Polyacrylate Leveling Agents: Provide good flowability and anti-cratering properties, but exhibit average substrate wettability and may affect gloss levels.

• Polyester Leveling Agents: Deliver comprehensive advantages, including enhanced fullness, excellent compatibility, high transparency and gloss, superior leveling performance, and easy foam elimination, making them a well-rounded choice for diverse applications.
