DOWSIL 2200 is a high-performance silicone-based antifoam engineered for demanding industrial environments. Its unique polysiloxane-polyether composite structure maintains activity in pH 2–12 and temperatures ≤150°C, reducing dynamic surface tension to 22–25 mN/m—ideal for high-shear, high-solids systems like fermentation broths and textile dye pastes. With micron-level dispersion technology, it enables rapid bubble collapse (≤10 sec) and long-lasting foam suppression (8+ hours), while remaining compatible with anionic/nonionic surfactants to minimize defects in coatings/adhesives and boost yield by 15%–30%.
Broad-Spectrum Efficiency: Acts on micron-to-millimeter bubbles, especially effective in viscous media (e.g., printing pastes).
Extreme Condition Stability: Remains active in strong acid/alkali (pH 2–12) and high-salinity environments, suitable for wastewater treatment.
Low-Dosage Persistency: Recommended usage of 0.05%–0.3% cuts costs by reducing frequent recharging.
Eco-Compliance: APEO-free, VOC<50g/L; meets EU REACH and China GB 24408.
Easy Integration: Water-dispersible emulsion, directly addable during grinding or post-dilution.
Bio-Fermentation: Controls foam in antibiotic/enzyme production to reduce fermenter overflow.
Textile Dyeing: Eliminates foam in reactive dye printing and polyester HT dyeing for uniform fastness.
Industrial Coatings: Prevents roller-coating bubbles/craters in epoxy floor and coil coatings.
Metalworking Fluids: Suppresses foam in cutting/quenching oils to extend fluid life.
