How to Distinguish Water-Based vs Oil-Based Defoamers? Chemi Tech's Guide

In industrial processes, defoamers are essential for foam control, but water-based and oil-based variants differ significantly in composition and usage. How to tell them apart? Chemi Tech, a professional defoamer brand, shares practical methods.  

1. Composition Differences  

- Water-Based Defoamers: Use water as a carrier, containing silicone or polyether compounds. Ideal for aqueous systems (e.g., coatings, wastewater).  

- Oil-Based Defoamers: Use mineral oil or synthetic esters, suitable for non-aqueous systems (e.g., lubricants, oily inks).  

2. Solubility Test  

Add a small sample to water:  

- Water-based types disperse easily with low turbidity;  

- Oil-based types float or form oil layers.  

3. Application Scenarios  

- Chemi Tech’s water-based defoamers (e.g., KM-320) suit eco-sensitive industries like pharmaceuticals and fermentation;  

- Oil-based series (e.g., KM-450) excel in chemical cleaning and cutting fliud.  

4. Brand Advantages  

Chemi Tech’s micro-emulsion technology enhances efficiency, with ISO-certified products and tailored solutions.  

Conclusion: Choose based on system polarity and environmental needs. Chemi Tech offers diverse options for industrial demands.
