Alcohol defoamers (fatty alcohols/modified alcohols) are silicone-free defoamers, formulated with high-grade fatty alcohols, emulsifiers, and dispersants. They are specifically designed for systems where silicone cannot be used or where silicone residue is unacceptable.

Core Parameters

Appearance: Colorless/pale yellow transparent liquid or white emulsion

Solid Content: 30%–100%

pH: 4–8

Temperature Resistance: ≤60℃ (room temperature type)

Features: Silicone-free, good compatibility, no demulsification, no residue, low price

Main Applications

Paper white water/drainage systems: No silicon residue, does not affect paper strength

Water-based coatings/inks: Avoids silicon pinholes and spots

Wastewater treatment: Aeration tanks, circulating water, landfill leachate

Metal cleaning/cutting fluids: Low foaming, easy to clean

Textile pretreatment, adhesives, building materials, desulfurization, and other silicon-sensitive systems

Product Advantages

✅ Completely Silicone-Free: No silicon spots, does not affect subsequent coatings/filter membranes

✅ Excellent Compatibility: Easily dispersed in water, not prone to demulsification and oil floating

✅ High Cost-Effectiveness: Lower price than organosilicon, good performance at room temperature

✅ Easily Biodegradable: Less environmental impact
