DOW XIAMETER ACP-7300 is a 100% active silicone defoamer concentrate designed for tough industrial settings. It appears as a gray-white translucent liquid (viscosity 2,800-3,500 cP) and keeps stable performance under temperatures up to 150°C and pH 1-14, breaking down micron-level foam in 30 seconds (with over 8 hours of suppression). Certified by FDA 21 CFR 175.300, it lowers mineral oil defoamer usage by 35% in textile dyeing and emulsion polymerization processes.
Fast Defoaming Speed: Nano silicone particles lower surface tension to 23 dyn/cm (in 0.5% solution), enabling rapid foam collapse.
Wide Compatibility Range: Remains stable in ketones, esters, and aromatic hydrocarbons, suitable for multiple solvent-based scenarios.
Textile Dyeing: Controls foam in jet dyeing machines, with a recommended dosage of 0.01%-0.05% to ensure smooth dyeing processes.
Chemical Polymerization: Improves monomer conversion in emulsion systems, enhancing the efficiency and quality of polymerization.
Food Processing: Suppresses foam in fermentation broths, with a residue limit of ≤15 mg/kg to meet food safety standards.
