DOW XIAMETER APW-4248 is a 12% active silicone powder defoamer for extreme industrial environments. It exists as white-to-cream free-flowing granules (density 0.7 g/cm³) and maintains stable performance under pH 3-10 and ≤90°C, enabling 12+ hours of long-term foam suppression in detergent powders and cement mortars. Certified by ISO 9001 and REACH, its optimized blending efficiency cuts liquid defoamer consumption by 60% in high-humidity powder systems
Storage Stability: Retains >95% activity after 12 months in 30°C/80% RH environments.
Instant Dispersion: Free-flowing granules (550 μm D50) integrate seamlessly without premixing.
Broad Compatibility: Effective in sulfate/carbonate-based detergents and variable water hardness systems.
Eco-Compliance: APEO-free, compliant with FDA 21 CFR 173.340 and EU Regulation 1333/2008.
Cost Efficiency: Delivers 40% higher foam control efficiency than mineral oil defoamers at 0.5%-3.5% dosage.
Detergent Production: Controls foam in laundry powders (0.5-3.5% dosage).
Cement Mortar: Reduces air voids in high-solids mortar mixing (pH 8-10 systems).
Powder Coatings: Eliminates microbubbles in resin-based formulations.
Paper Manufacturing: Extends membrane lifespan in deinking wastewater treatment.
