DOW XIAMETER ACP-3522 Defoamer

DOW XIAMETER ACP-3522 is A 100% active silicone defoamer for harsh industrial use, it’s a colorless transparent liquid (2,000 mPa·s viscosity) working stably at pH 1-14 and ≤150°C. It quickly collapses foam (72+ hours suppression) in waterborne coatings and epoxy systems, meets ISO 9001/REACH, and cuts consumption by 60% via better dispersion in high-shear processes.


Product Information of DOW XIAMETER ACP-3522 Defoamer

  1. Wide pH Adaptability: Works in pH 1-14 systems like acidic electroplating wastewater.

  2. High-Temp Stability: Keeps activity at ≤150°C without performance drop.

  3. Nano-Grade Effectiveness: 5 μm particles boost penetration in nano-coatings.

  4. Food-Grade Safe: Complies with FDA 21 CFR 175.300 for food packaging use.

  5. Better Cost-Saving: 45% higher defoaming efficiency than polyethers at 0.01%-0.1% dosage.

Areas of Application of DOW XIAMETER ACP-3522 Defoamer

  1. Waterborne Coatings: Stops pinholing in latex paints (0.02-0.1% dosage).

  2. Epoxy Resins: Controls foam during 120°C polymerization reactions.

  3. Industrial Cleaning: Reduces foam in pH 14 alkaline degreasers.

  4. Food Packaging: Manages foam in adhesives (meets GB 9685-2016).
