Widely Used Leveling Agent

Basic principles and characteristics of leveling agents

The principle of action of leveling agents is mainly based on their surface activity characteristics. During the coating process of paint or ink, leveling agents automatically form a thin film on the surface of the coating, and by reducing surface tension and accelerating molecular movement, the coating spreads uniformly on the surface, thereby achieving leveling effect. A good leveling agent can improve the uniformity and adhesion of the coating surface, reduce bubbles in the coating, and avoid the generation of brush marks or drag marks.

Improve coating adhesion

By enhancing the adhesion between the substrate and the coating, leveling agents can improve the adhesion and durability of the coating, preventing coating detachment or peeling.

Reduce bubbles and foam

Leveling agent can effectively eliminate bubbles and foam in the coating, prevent bubbles from forming during the drying process of the coating, and ensure the compactness and uniformity of the coating.

Improve the surface smoothness of the coating

Leveling agents can effectively improve the flowability of coatings, avoid the formation of irregular patterns, bubbles, brush marks and other defects on the coating surface, and ensure a smooth and even coating surface.

Enhance the glossiness of the coating

Leveling agents help improve the glossiness of coatings, presenting a more uniform gloss on the surface of the coating and enhancing the overall quality of product appearance.

Coatings and inks

In architectural coatings, automotive coatings, industrial coatings, and inks, leveling agents can improve the glossiness and leveling of coatings, avoid defects during the coating process, and enhance the visual effect and performance of coatings.

Plastic processing

During plastic coating, film and injection molding processes, leveling agents help improve surface smoothness, prevent surface roughness or bubbles, and enhance the appearance quality of products.

Adhesives and sealants

In the production process of adhesives and sealants, leveling agents help to improve the fluidity and uniformity of the product, ensure the smoothness of the bonding area, and enhance the bonding strength.

Leather and Textile

Leveling agents are also widely used in leather processing and textile coatings to improve the surface smoothness of products, enhance the adhesion and gloss of coatings.

Choose the appropriate leveling agent

The demand for leveling agents varies among different types of coatings or substrates. When choosing a leveling agent, the appropriate product should be selected based on factors such as the type of coating, substrate characteristics, and application environment to ensure optimal results.

Add in moderation

The amount of leveling agent added needs to be controlled according to the actual situation. Excessive use may cause the coating surface to be too smooth, and even lead to problems such as coating foaming and peeling. Generally speaking, the recommended dosage should be added according to the formula of the coating.

Compatibility with other additives

Leveling agents need to be compatible with other additives in the coating (such as dispersants, defoamers, etc.) during use to avoid a decrease in leveling effect or other adverse reactions caused by interactions.

Leveling agents should be stored in a cool and dry environment, avoiding direct sunlight and high temperatures to ensure product stability. After opening the packaging, it should be used up as quickly as possible.

Before formal application, it is recommended to conduct small-scale experiments to confirm the effectiveness of leveling agents in specific formulations, and optimize the formulation and usage methods based on the test results.

summary

Leveling agents, as important additives in coatings and other surface treatment agents, can significantly improve the surface smoothness, glossiness, and adhesion of coatings. Its wide application in industries such as coatings, inks, plastics, adhesives, etc. not only improves the appearance quality of products, but also enhances their performance. When using leveling agents, the appropriate type should be selected according to actual needs, and the usage amount should be strictly controlled to ensure the best effect and product performance.
