Leveling Agents for Paint and Coatings

Flatness is a characteristic of coatings that determines the aesthetic appearance of the coating surface.It refers to the ability of the coating to eliminate surface defects that occur after construction, which are usually not immediately apparent after construction.These defects are mostly caused by local surface tension differences of the involved raw materials, substrate contaminants, or surface tension differences caused by solvent evaporation, such as orange peel tissue, structured surfaces, meteorite craters, fish eyes, crawling, brush marks, pinholes, etc. The use of leveling agents can effectively improve these defects.

China AAB Group  Multifunctional leveling agent is an efficient surface modification additive widely used in coatings, inks, adhesives and other fields. By reducing surface tension and eliminating surface defects (such as orange peel, shrinkage, brush marks), it endows coatings with excellent smoothness, glossiness and adhesion.

The main function of leveling agent 

• Reduce surface tension: Leveling agents can reduce the surface tension of coatings, making them easier to flow and spread on the surface.

• Improve mobility and leveling: By reducing surface tension, leveling agents can promote better flow and leveling, resulting in smoother and more uniform coatings.

• Preventing surface defects: Leveling agents help prevent common coating defects such as shrinkage, fisheye, and orange peel by allowing the coating to flow out and fill in defects.

• Improve surface appearance: Leveling agents improve the overall smoothness and glossiness of coatings, making them more attractive and professional in appearance.

 Frequently Asked Questions (FAQ)

Q1: What are the effects of excessive addition of leveling agents?

→ It may cause coating shrinkage or decrease in interlayer adhesion, and should be added strictly according to the recommended dosage.

Q2: How to test the compatibility of leveling agents with the system?

Suggest conducting small-scale coating experiments or contacting our company to inquire about compatibility.

Q3: Can it be used in high polarity resin systems?

AAB has leveling agent products specifically designed for polar systems, which can avoid surface defects.

Q4: How to choose the appropriate type of leveling agent?

Three key factors need to be considered: ① substrate surface energy ② coating system characteristics ③ construction environmental conditions.Our engineers can provide professional selection guidance.
