Precautions for leveling agents

Precautions for leveling agents:

I believe everyone has a certain understanding of leveling agents. Now, let me briefly explain to you the precautions for using these leveling agents before and during their selection process.

1. Choose leveling agent based on the problem. Silicon leveling agent is a "universal type" that can solve any problem. If the choice is incorrect, it will have a negative impact.

2. Interlayer adhesion. Although the compatibility and adhesion of silicone leveling agents have been improved after modification, there are still some issues. For leveling agents with poor fluidity, problems are prone to occur when applying the second layer after the coating is completely dry.

3. Thermal stability. When used for heating curing coatings, attention should be paid to the heat resistance range of the leveling agent, and the baking temperature should be within the heat resistance range of the leveling agent.

4. Usage issue. The dosage depends on the need. The total recommended dosage is 0.01% -1.0% of the paint quantity. The appropriate dosage depends on the formula composition, solvent solubility, resin compatibility, interactions between additives, and other factors.
