DOW XIAMETER ACP-1920 (EU) is a 100% active silicone-silica composite defoamer developed for industrial scenarios that call for food-grade qualification. It presents as an opaque light gray liquid (viscosity 900 mPa·s) and retains stable performance under pH 2-12 and ≤100°C, clearing micron-scale foam in 5 minutes (with foam suppression lasting over 6 hours). Holding triple certifications—FDA 21 CFR 175.300, EU 10/2011, and GB 9685-2016—it cuts mineral oil defoamer consumption by 20% in agrochemical and food processing systems.
Food-Grade Qualification: Complies with FDA 173.340 and EU 95/2 directives for direct food contact, such as in jam and canned vegetables, with residue limits capped at ≤10 mg/kg.
Severe Process Resistance: Functions normally in pH 2-12 environments and can stand up to steam sterilization procedures.
Self-Dispersing Property: Dilution with cold water enables fast dispersion, making it suitable for automated dosing systems.
Eco-Friendly Safety: Free of APEO, meets REACH and RoHS standards, and has VOC content below 2%.
Cost-Saving Efficiency: Takes effect at an initial dosage of 10 ppm, reducing costs by 15% compared to traditional defoamers.
Agrochemicals: Manages foam in powdered pesticide slurries, with a recommended dosage of 0.005%-0.05%.
Food Processing: Suppresses foam during jam production and adheres to EU 79/693/EEC regulations.
Paper Manufacturing: Lowers fiber loss in pulp deinking processes.
Wastewater Treatment: Enhances efficiency in treating industrial effluents with pH ranging from 1 to 13.
