How to Add Defoamer to Chemi Tech Acrylic Anti-Corrosion Paint

Acrylic anti-corrosion paints are widely used in industrial equipment, bridges, and steel structures due to their excellent weather resistance and protective properties. However, foam formation during application can compromise film appearance and performance. Chemi Tech’s defoamers (e.g., KM-300 series) offer an effective solution. Here’s a professional guide:  

1. Defoamer Selection 

Chemi Tech defoamers are designed for water/solvent-based acrylic systems, featuring rapid bubble-breaking and long-term foam suppression.  

2. Recommended Dosage 

Recommended dosage is 0.1%-0.5% of total paint weight, adjustable based on environmental conditions (temperature, humidity) and paint viscosity. Overuse may cause craters or adhesion issues.  

3. Mixing Procedure 

- Pre-mixing: Blend Chemi Tech's defoamer with a small amount of base material before adding to the main paint.  

- Low-speed stirring: Use a mechanical mixer (300-500 rpm) for 10-15 minutes to avoid new foam generation.  

4. Key Notes  

- Pre-test: Conduct small-scale trials to check compatibility.  

- Storage: Keep defoamers sealed in cool conditions to prevent separation.  

By following these steps, Chemi Tech defoamers can optimize paint leveling and film density, ensuring durable anti-corrosion coatings.
