Classification and characteristics of leveling agents

  After the coating is applied, there will be a process of flow and drying to form a film, gradually forming a flat and uniform coating. However, during the coating leveling and film formation process, characteristic defects such as shrinkage and pinholes often occur. At this time, leveling agents need to be added to give the coating appropriate surface tension and reduce the surface tension gradient.

There are many types of leveling agents, generally including the following:

   1. Defoamer leveling agent:Mainly used to eliminate the stirring bubbles generated during the use of medium to high viscosity coatings and the air bubbles generated during coating application such as spraying, brushing, and spraying.

2. Special anti foaming leveling agent:This leveling agent not only suppresses the bubbles generated during the production and spraying of coatings, but also makes the coating smooth, and there will be no defects such as adhesion between coatings when reapplying.

3. Smooth leveling agent:It can improve the clarity, transparency, glossiness, and smooth touch of the coating.

4. Rapid defoamer:In addition to helping the paint quickly break bubbles during spraying and immersion, it can also increase the brightness and dryness of the coating appropriately, suppress color separation and floating, and prevent shrinkage holes.

  5. Defoamer for solvent based coatings:It can eliminate bubbles and depressions, produce a flat coating, and enhance the coating and scratch resistance.

The above introduction is about the classification and characteristics of leveling agents, hoping to be helpful to everyone
