Characteristics and efficacy of ink leveling agents

Characteristics

Low surface tension: ink leveling agents can significantly reduce the surface tension of ink, which is its key characteristic to promote uniform distribution and leveling of ink.

Good viscosity reduction and leveling: leveling agents can improve the fluidity and leveling of ink, making it easier for ink to spread and flow during printing, thereby obtaining a smoother and more uniform printing effect.

Wide applicability: ink leveling agents are suitable for a variety of inks and printing processes, including solvent-based coatings, water-based coatings and ink systems.

Diverse chemical structures: leveling agents can be divided into acrylic, silicone and fluorocarbon compounds according to their chemical structures. Different types of leveling agents have different characteristics and application advantages.

Efficacy

Preventing shrinkage: ink leveling agents can effectively balance the surface tension of inks, prevent shrinkage caused by surface tension differences, and thus improve the quality of printed products.

Promote ink spreading and flow: leveling agents can enhance the spreadability of inks, ensure that the ink can fully cover the surface of the substrate, and reduce surface defects such as brush marks and rolling marks.

Improve the quality of printed products: The use of ink leveling agents can significantly improve the surface quality of printed products, making the printed patterns clearer and more delicate, while reducing the scrap rate and improving production efficiency.

Improve coating performance: In some applications, leveling agents can also improve the smoothness, glossiness and other properties of the coating, and enhance the overall texture of the product.

Enhance adaptability: Ink leveling agents can adapt to different printing conditions and substrate surface conditions, ensuring that the ink can achieve good leveling effects under various conditions.
