Inorganic Powder Overload Causes Coating Foaming? Chemi Tech Defoamer Solutions

In coating production, inorganic powders (e.g., calcium carbonate, talc) improve hardness and wear resistance. However, excessive usage often increases viscosity, causes poor dispersion, and generates persistent foam. Foam negatively impacts leveling, appearance, and application efficiency. 

Chemi Tech addresses foam issues caused by inorganic powder overload with advanced defoamers. Their molecular structure rapidly penetrates foam surfaces, breaks liquid film elasticity, and delivers instant defoaming with long-term suppression. Key advantages in high-powder systems include:  

1. Fast Action: Eliminates micron-sized bubbles at low dosage (0.1%-0.3%);  

2. High Stability: Resists high temperature/shear and maintains compatibility;  

3. Zero Side Effects: Prevents craters or gloss loss while preserving adhesion.  

Tests show foam volume reduces by 90%+ in coatings with >35% inorganic powder, with no foam recurrence after 30-day storage.
