How to Eliminate Bubbles in Coatings? Chemi Tech Defoamer Solutions 

Bubbles trapped in coatings during production or application are a common defect. They compromise appearance, adhesion, and mechanical properties. Chemi Tech specializes in defoamer formulations to eliminate micro and macro bubbles efficiently.  

Causes of Bubbles  

1. Air Entrainment: High-speed mixing introduces air into the system.  

2. Gas Release: Chemical reactions of resins or additives generate gas.  

3. Surface Tension Imbalance: Low surface tension areas stabilize bubbles.  

Chemi Tech Defoamer Mechanism  

- Fast Bubble Breaking: Reduces surface tension to rupture bubbles instantly.  

- Long-term Suppression: Prevents new bubble formation.  

- Broad Compatibility: Works in water-based, solvent-borne, and solvent-free systems without affecting performance.  

Application Tips  

- Timing: Add during the grinding phase for uniform dispersion.  

- Dosage: Optimize at 0.1%-0.5% based on viscosity and bubble severity.  

- Testing: Conduct lab trials to finalize the formula.  

Chemi Tech defoamers are widely used in industrial coatings and wood paints, proven to reduce defects and improve productivity. For technical support, contact Chemi Tech experts for tailored solutions.
