DOW XIAMETER AFE-0800 is a 30% active siloxane emulsion defoamer built for harsh industrial settings. It is a milky white liquid (950-1,350 cP dynamic viscosity), performs stably at pH 2-14 and ≤100°C (0.5% solution surface tension: 21.5 dyn/cm), and quickly breaks bubbles with over 48 hours of suppression in 6 bar high-pressure, high-shear systems.
Process Adaptability: Functions in pH 6-12 systems, including caustic pulping baths.
Shear Stability: Maintains consistency under 10,000 rpm shear with no viscosity changes.
Nanoscale Performance: 5 μm particle size boosts penetration in nano-coatings.
Eco-Compliant: Contains no APEO and meets FDA 21 CFR 175.300 standards.
Long-Lasting Foam Control: Lowers foam regeneration rate to <5% in aeration tanks.
Waterborne Coatings: Eliminates fisheye flaws in latex paints (0.05-0.15% dosage).
Metalworking Fluids: Controls foam in cutting oil systems (pH 8-10).
Paper Pulping: Improves drainage efficiency in kraft pulping (pH 12-13).
Industrial Cleaning: Suppresses foam in alkaline degreasers (pH 14).
Textile Dyeing: Reduces steam consumption in jet dyeing machines.
