The pursuit of flawless surfaces in coatings, inks, and plastics often hinges on the precise control of surface tension. NINGBO INNO PHARMCHEM CO.,LTD. specializes in providing advanced silicone leveling agents, such as our Polyether Modified Silicone Leveling Agent, that are engineered to manipulate these critical surface properties. Understanding the science behind these additives is key to unlocking their full potential.

At its core, a leveling agent functions by reducing the surface tension of a liquid formulation. Surface tension is the force that makes liquid molecules adhere to each other more strongly than to the surrounding air. In coatings, if the surface tension of the liquid is higher than that of the substrate, or if there are localized differences within the coating itself, it can lead to defects like cratering, fisheyes, and poor wetting. Silicone leveling agents, due to their unique molecular structure, are highly effective at drastically lowering this surface tension.

This reduction in surface tension allows the coating to spread more evenly across the substrate, ensuring uniform coverage and preventing the formation of surface imperfections. The improved wetting that results is fundamental to achieving a smooth, high-gloss finish. Our products are designed to facilitate this process, offering a solution for formulators aiming to improve substrate wetting and enhance surface characteristics.

The prevention of specific defects, such as Bernard vortices, is another crucial aspect addressed by these agents. These vortices are caused by surface tension gradients that can arise during the drying process. By maintaining a consistent and low surface tension, our silicone additives help to stabilize the film and prevent these disruptive patterns, ensuring a superior aesthetic outcome.

NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing formulators with the tools they need to overcome these challenges. Our expertise in silicone chemistry ensures that our leveling agents not only perform effectively but also offer compatibility across various systems, including water-based and solvent-free formulations. Choosing the right additive means selecting one that can reduce surface tension coating additive properties efficiently, leading to better overall product quality.
