DOWSIL SH 5507 (M) Defoamer

DOW DOWSIL SH 5507 (M) is a siloxane emulsion-based defoamer built for high-shear industrial uses. It comes as a milky liquid (800-1,500 mPa·s viscosity), stays actively stable at pH 2-12 and ≤80°C, has dynamic surface tension down to 25 dyn/cm, quickly collapses micron foam (8+ hours suppression), and holds ISO 9001 certification. It performs well in coatings and inks, cutting mineral oil defoamer use by 20% while boosting production uniformity.

Product Information of DOWSIL SH 5507 (M) Defoamer

  1. Nano-Scale Defoaming: Siloxane-silica particles break foam in 3 minutes, perfect for high-speed dispersion processes.

  2. Extreme Condition Resistance: Withstands pH 2-12, high salinity, and 80°C heat without performance degradation.

  3. Wide Compatibility: Works well with acrylic and polyurethane resins, reducing coating defects effectively.

  4. Eco-Friendly Safety: APEO-free, VOC <50g/L, and compliant with EU REACH and China GB/T 35602-2017 standards.

Areas of Application of DOWSIL SH 5507 (M) Defoamer

  1. Coatings: Manages foam in water and solvent coatings, increasing gloss by 15% when dosed at 0.1%-0.3%.

  2. Pulp Processing: Lessens fiber loss during deinking and bleaching procedures in pulp production.

  3. Synthetic Fiber: Curbs foam in spin finishes, helping to reduce yarn breakages in fiber manufacturing.
