Highly effective in suppressing foam formation and promoting rapid defoaming in oil-based systems.
Excellent compatibility with mineral oils, synthetic lubricants, and hydrocarbon-based formulations.
Thermally stable across a broad operating temperature range, maintaining performance under elevated process conditions.
Low dosage efficiency — delivers robust defoaming action at low treat rates (typically 0.01–0.1 wt%).
Non-silicone chemistry avoids residue, staining, or interfacial incompatibility issues common with silicone-based defoamers.
Industrial metalworking fluids, including cutting oils and grinding fluids.
Hydraulic and turbine oils requiring long-term foam control.
Transformer oils and dielectric fluids where electrical insulation integrity is critical.
Engine oils and gear lubricants for automotive and heavy-duty applications.
Oil-based coatings, inks, and adhesives where surface defect prevention is essential.
