DOW DOWSIL FS 80 is a 100% solids, water-dilutable silicone defoamer made for high-pressure dyeing (e.g., jet-drying machines). It uses self-emulsifying tech (3,000 mPa·s viscosity) to stay active under high temp (>100°C) and pressure, has 20.0 dyn/cm surface tension (0.5% solution), quickly eliminates micron foam (6+ hours suppression), cuts textile dyeing oil spots by 30%, and works with anionic/nonionic surfactants.
High-Pressure Suitability: Tuned for 300-500 kPa gear (like jet dryers) with no performance drop.
Auto-Emulsifying: Disperses automatically in water at 1:10 dilution—no extra equipment needed.
Heat Resistance: Endures 100°C continuously and 150°C short-term, fit for thermosol dyeing.
Fabric-Friendly: Lowers oil spots and back-staining, boosting fabric yield by 15%.
Eco & Efficient: Zero VOC, 100% active content lets dosage drop to 0.1%-0.5%.
Textile Jet Dyeing: Manages foam in dyeing machines to reduce waste (0.2%-0.8% dosage).
Industrial Drying: Curbs foam in spray dryers and prevents clogging.
Pulp Processing: Defoams high-temperature pulp to cut fiber loss.
Chemical Reactors: Controls foam in high-pressure vessels for smooth, efficient reactions.
