Dowsil ACP-3472 Defoamer

DOWSIL ACP-3472 is a 100% active silicone defoamer engineered for harsh industrial environments, formulated with silica-filled polydimethylsiloxane and silicone copolymer. It has a dynamic viscosity of 20,000–30,000 cP and a flash point >100°C, maintaining stable activity within pH 6–8. This defoamer enhances kraft/sulfite pulping efficiency (20%+ energy reduction) and complies with FDA 21 CFR 176.170/180/210, making it suitable for eco-sensitive applications like food-grade pulp. When blended, it reduces mineral oil defoamer usage by 30%.

Product Information of Dowsil  ACP-3472 Defoamer

  1. Ultra-Economical Dosage: Delivers equivalent effects at 1/20–1/40 the usage of traditional mineral oil defoamers, cutting costs by 40%.

  2. Harsh Condition Tolerance: Resists high temperatures (>100°C) and shear, ideal for 80–100°C kraft pulping.

  3. Rapid Emulsification: Pre-emulsified liquid form allows direct dosing, forming a stable emulsion within 5 minutes.

  4. Eco-Compliance: APEO-free, VOC<50g/L; certified under EU REACH and China GB 24408.

Areas of Application of Dowsil  ACP-3472 Defoamer

  1. Chemical Pulping: Suppresses black liquor foam, minimizing fiber loss (0.05%–0.2% dosage).

  2. Paper Bleaching: Controls foam in H₂O₂ bleaching for uniform whiteness.

  3. Food Processing Wastewater: Manages foam in fermenters/wash lines, meeting indirect food contact standards.

  4. Industrial Wastewater: Reduces foam in high-COD aeration tanks, lowering sludge carryover.
