Corechem Additives - A Technology-Driven Manufacturer

As a key material for protection, decoration, and value enhancement of products, coatings' performance and appearance are of vital importance. However, various surface defects such as pinholes, orange peel, and ripples often occur during coating application. These issues not only affect the appearance but also reduce the coating's performance and service life. Corechem's Polyester Leveling Agent helps you perfectly solve coating surface defects!

Unique Advantages of Polyester Leveling Agent

Compared with traditional silicone and polyacrylate leveling agents, Corechem's Polyester Leveling Agent has unique advantages:

• Enhanced Fullness: It significantly improves the fullness and three-dimensional sense of the film, endowing the coating with a more plump and vivid effect. This is because the polyester molecular structure can effectively fill the tiny pores on the film surface, making the film tighter and flatter.
• High Transparency and Gloss: It maintains high transparency and gloss of the film, enhancing the visual effect of the coating and making the product more attractive and high-grade.
• Excellent Leveling Performance: It effectively reduces surface defects such as pinholes, orange peel, and ripples, making the film smoother and flatter, and improving the weather resistance, corrosion resistance, and wear resistance of the coating.
• Easy Defoaming: It facilitates foam elimination, avoiding coating defects caused by foam and improving product qualification rate and production efficiency.
• Molecular Structure Design: It adopts a special molecular structure design, which can effectively reduce the surface tension of the coating system, thereby improving the leveling property of the film. The long-chain polyester structure in the molecule helps form a uniform molecular arrangement in the coating, reducing film defects.
• Compatibility: It has excellent compatibility and can be compatible with various resin systems, including alkyd resin, acrylic resin, polyester resin, etc., without causing flocculation or phase separation of the coating system.
• Heat Resistance: It remains stable in a wide temperature range. Even in high-temperature baking coatings, it can exert an excellent leveling effect without affecting the final performance of the film.
• Anti-Cratering Property: The special polyester structure helps prevent the formation of surface defects such as craters and fisheyes during film drying, ensuring a smooth and uniform film surface.
• Environmental Friendliness: It is produced with environmentally friendly processes, reducing environmental impact and meeting the demand for green and environmentally friendly products in the current coating industry.

Performance Differences Between Types

To better select the appropriate leveling agent, it is necessary to understand the performance differences between different types of leveling agents:

• Silicone Leveling Agent: Has excellent leveling performance and substrate wettability, but is prone to foam generation and may affect interlayer adhesion.
• Polyacrylate Leveling Agent: Has good fluidity and anti-cratering property, but has general substrate wettability and may affect gloss.
• Polyester Leveling Agent: Has the advantages of enhanced fullness, excellent compatibility, high transparency and gloss, excellent leveling performance, and easy defoaming, making it a leveling agent with comprehensive overall performance.
