What are the chemical-action leveling agents?

What are the chemical-action leveling agents?

A leveling agent, also known as a surfactant, is a chemical substance that can reduce the surface tension of liquids and improve their surface properties. Typically composed of a hydrophobic group and a hydrophilic group, these agents adsorb onto the liquid surface to form a molecular layer, thereby lowering the surface tension of the liquid. Leveling agents are widely used additives in fields such as coatings, inks, and adhesives. They enable these substances to form a uniform film on surfaces and impart excellent gloss and smoothness.

What are the physical-action leveling agents?

What are the physical-action leveling agents?

In the coatings industry, leveling property is one of the key indicators for assessing the quality of a coating. It directly affects the smoothness and glossiness of the coated surface, thereby influencing the aesthetic appeal and durability of the final product. To enhance the leveling property of coatings, the industry has developed a series of leveling agents. Among these, physically acting leveling agents have attracted considerable attention due to their unique physical mechanisms and broad range of applications. These leveling agents achieve improved leveling by adjusting the viscosity, leveling time, or surface properties of the coating—without undergoing any chemical reactions with the coating system itself.

Resins with Various Curing Methods (Part 2)

Resin materials have attracted considerable attention due to their unique properties and wide range of applications. As a crucial step in the application of resin materials, resin curing technology plays an important role in enhancing material performance and expanding its application fields. In the previous issue, we discussed two major types of resin curing technologies: UV-curable resins and visible-light-curable resins. In addition to these, this article will introduce three other distinct types of resin curing technologies—IR-curable resins, thermally cured resins, and water-curable resins. Each of these curing technologies has its own distinctive features and is suited to different application scenarios, offering greater flexibility and more possibilities for the use of resin materials.
