Key Factors for Selecting Defoamers in Water-Based Coatings & Chemi Tech Solutions

In water-based coating production, foam issues directly affect film quality and application efficiency. How to scientifically select defoamers? Chemi Tech summarizes key considerations based on industry expertise:  

1. Compatibility & Stability  

Defoamers must integrate with the coating system to prevent craters or oil floating. Chemi Tech’s molecular-level design ensures stability during storage and application.  

2. Dynamic Defoaming Efficiency  

Foam generation intensifies under high-speed dispersion or spraying. Chemi Tech defoamers rapidly collapse bubbles, especially under high-temperature or high-shear conditions.  

3. Long-Term Foam Suppression  

Some defoamers offer only temporary effects. Chemi Tech’s modified components inhibit foam recurrence, extending coating workability.  

4. Gloss Preservation  

Certain defoamers cause haze. Chemi Tech controls particle size precisely to maintain film gloss while eliminating foam.  

Chemi Tech provides a range of defoamers tailored for water-based coatings, addressing needs from production to application. Backed by lab data and field results, their products balance defoaming efficiency and system compatibility across diverse resin systems.
