Defoamer (SILICONE DEFOAMER 204)

Description

1. Product Overview

SILICONE DEFOAMER 204 is a high-performance, non-ionic aqueous emulsion designed for rapid foam knockdown and long-term foam suppression across demanding industrial processes. It is primarily utilized in water-based systems including chemical manufacturing, wastewater treatment, and agrochemical production where uncontrolled foam reduces efficiency and product quality. With exceptional dispersion stability and defoaming efficacy at low concentrations, this product delivers measurable reductions in process downtime and operational costs, making it a strategic enabler for continuous, high-throughput operations.

2. Key Specifications & Technical Characteristics

• Chemical Composition: Polydimethylsiloxane (PDMS)-based emulsion with proprietary hydrophobic silica particles

• Purity / Active Solids: 20–25% non-volatile matter (active silicone content)

• Physical Form: White to off-white, free-flowing liquid emulsion

• Viscosity: 1,000–3,000 cP (Brookfield, spindle 2 at 25°C)

• Density: Approximately 1.00 g/cm³ at 25°C

• pH (as supplied): 6.5 – 8.0

• Particle Size: < 5 microns (ensuring rapid spreading and foam penetration)

• Packaging Options: 25 kg HDPE drum, 200 kg HDPE drum, 1,000 kg IBC tote

• Shelf Life: 12 months when stored in original, unopened containers at 5–40°C, protected from freezing and direct sunlight

3. Core Industrial Applications

• Chemical Manufacturing: Controls foam in polymerization, distillation, and solvent recovery units – reduces carryover and improves yield.

• Wastewater Treatment: Prevents foam overflow in aeration tanks and sludge thickening processes – lowers defoamer consumption by 30–40% compared to non-silicone alternatives.

• Agrochemical Formulation: Stabilizes high-shear mixing of herbicides, fungicides, and suspension concentrates – eliminates microbubbles that compromise homogeneity.

• Textile Processing: Suppresses foam in jet dyeing and finishing baths – enables higher fabric throughput without foam-related stoppages.

• Paints & Coatings: Provides long-term foam control during grinding and letdown stages – avoids surface defects in finished films.

Why it outperforms: Unlike oil-based or powdered defoamers, SILICONE DEFOAMER 204 maintains efficacy under wide pH ranges (2–12) and moderate temperatures (up to 80°C), with no fish-eye formation or surface contamination.

4. Competitive Advantages

• Quality Consistency: Manufactured under ISO 9001:2015-certified process; each batch validated for viscosity, active content, and defoaming speed via standardized ASTM E2407 foam collapse test.

• Supply Reliability: Dual-sourced raw materials and safety stock buffers ≥30 days of global demand; no documented supply disruption in 6+ years.

• Logistics Capability: Hub-and-spoke warehousing in North America, Europe, and Southeast Asia enabling 5-day average lead time to industrial zones.

• Price Competitiveness: Direct manufacturer-to-market model with volume tiering that reduces cost-per-liter by 15–25% vs. specialty chemical distributors.

• Sustainability & Safety: Non-hazardous classification (no VOC label, no SARA 313 reportable components); 100% recyclable packaging options available.

• Technical Support: Full documentation suite including SDS, TDS, batch COA, and on-call application engineering for dosage optimization (typical use: 10–300 ppm).

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): BULK 20 MT (flexible for first-time buyers with credit approval)

• Loading Capacity: 20 MT per standard 20-foot container (80 x 25 kg drums or 1 x 20’ FCL with IBCs)
