DOW XIAMETER AFE-0119 is a silicone-based defoamer emulsion designed for harsh industrial settings. It appears as a milky-white liquid (viscosity 2,200-2,800 cSt) and maintains stable performance under pH 1-14 and temperatures from -20°C to 120°C, breaking down micron-level foam within 3 minutes (with over 8 hours of suppression). Certified by ISO 9001, its optimized dispersion efficiency cuts mineral oil defoamer usage by 35% in PCB manufacturing and paper pulp processing.
Extreme Process Resistance: Functions in pH 1-14 systems—including electroplating waste treatment—adapting to highly demanding industrial conditions.
Fast Defoaming Action: Nano silicone particles lower surface tension to 23.5 dyn/cm (in 0.5% solution), enabling rapid foam collapse.
Wide Compatibility: Remains stable in ketones, esters, and aromatic solvents, suitable for multiple solvent-based application scenarios.
Eco-Friendly Compliance: Free of APEO, and meets the requirements of REACH and GB 9685-2016 standards, aligning with environmental protection regulations.
PCB Manufacturing: Controls foam in acidic etching solutions, with a recommended dosage of 0.005%-0.03% to ensure precise etching and PCB quality.
Papermaking Industry: Enhances pulp deinking efficiency during black liquor treatment, improving pulp purity and reducing raw material waste.
Industrial Cleaning: Reduces foam in alkaline degreasers, applicable to pH 3-12 systems for thorough removal of industrial grease.
