DOW XIAMETER APW-4412 is a 12.5% active silicone powder defoamer for complex industrial use. It comes as off-white free-flowing granules (500 g/L bulk density), works stably at pH 3-10 and ≤90°C, and suppresses foam for over 12 hours in detergent powders and powder coatings. ISO 9001 and REACH certified, it cuts liquid defoamer use by 55% via better blending.
Excellent Thermal Resistance: Operates reliably in extreme temperature ranges from -20°C to 150°C, adapting to high-heat industrial workflows.
Self-Emulsifying Property: Compatible with aliphatic and aromatic solvents, enabling seamless integration into diverse non-aqueous systems.
Low Surface Tension: 21.5 mN/m (in 0.1% solution) accelerates foam collapse, enhancing defoaming speed and efficiency.
Eco & Safety Compliance: APEO-free and FDA-compliant, meeting strict environmental and food-contact safety standards.
Oil & Gas Processing: Controls foam in Fluid Catalytic Cracking (FCC) units (10-100 ppm dosage), ensuring smooth refining operations.
Industrial Cleaning: Suppresses foam in high-alkaline degreasers (pH 12-14), improving the penetration of cleaning agents and degreasing efficiency.
Chemical Reactors: Eliminates microbubbles in polymerization reactions, preventing defects in final polymer products.
Lubricant Production: Reduces air voids in high-viscosity oils, enhancing lubricant performance and service life.
