How to Effectively Eliminate Bubbles in Chemi Tech Coatings

Bubbles in coatings are a common quality issue, especially for high-performance products like Chemi Tech. They compromise aesthetics and protective properties. This article analyzes the causes and offers practical solutions.  

Common Causes of Bubbles  

1. Improper Mixing: Over- or under-mixing introduces air.  

2. Poor Substrate Preparation: Oil, moisture, or pores on the surface affect adhesion.  

3. Unsuitable Environment: High temperature, humidity, or poor ventilation accelerates solvent evaporation.  

4. Incorrect Viscosity: Thick or improperly diluted coatings trap air.  

Chemi Tech Bubble Removal Methods  

1. Controlled Mixing: Use low-speed stirrers and let the mixture rest for 5-10 minutes.  

2. Surface Preparation: Clean and sand the substrate; apply Chemi Tech primer if needed.  

3. Environment Control: Maintain 10-30°C temperature, <85% humidity, and adequate airflow.  

4. Viscosity Adjustment: Follow manufacturer guidelines for thinner ratios.  

5. Defoamer Application: Add 0.1%-0.5% Chemi Tech defoamer to suppress bubbles.  

Post-Application Checks  

For wet bubbles, lightly sand and recoat during the tacky stage. Cured bubbles require complete removal and reapplication.  

These methods ensure optimal performance and longevity of Chemi Tech coatings.
