Foam problems solved
Overflow, poor level control, reduced pump efficiency, slow drainage, surface bubbles.
Product Specialty Additives
Defoamer (Silicone-Free)
Silicone-free defoamer option for aqueous systems where silicone contamination is a concern—helping control foam, entrained air, and surface bubbles that can slow operations or impact product appearance.
Packaging: 25 kg / 200 L drums / 1000 L IBC / bulk (as applicable)
Documentation lane: SDS / TDS; COA on request
Grade selection: knockdown vs. persistence vs. air-release balance
Designed for silicone-sensitive operations (coatings/adhesives, paper, water-based process systems)
Export coordination: labeling + shipping docs aligned to destination requirements
Support for trials: dosage recommendations and compatibility checkpoints
Commercial overview
Foam is not just a nuisance—it can reduce pump efficiency, cause level control errors, increase cycle time, and trap air that compromises film appearance or downstream QC. Silicone-free defoamers are selected when even trace silicone can create surface defects (craters/fisheyes), adhesion failures, or contamination concerns in sensitive production environments.
- Controls foam to stabilize throughput and reduce downtime
- Helps release entrained air for improved clarity, filtration, and pump performance
- Silicone-free profile supports coating/adhesive and appearance-critical products
- Procurement lane: repeat specification + packaging + documentation flow
Applications
Typical usage patterns. Tell us your process and constraints and we’ll align the right specification (fast knockdown vs. persistence, air-release, and compatibility).
- Water-based coatings, adhesives, emulsions (silicone-sensitive)
- Industrial cleaning systems where foam disrupts tanks, pumps, and spray operations
- Process water / wastewater treatment foam control
- Paper & pulp processes (foam suppression and air release)
- Fermentation/process operations where entrained air impacts flow control (system-dependent)
Performance targets
Knockdown, persistence, air-release, minimal impact on gloss/clarity (by application).
Where it’s added
Make-down tank, recirculation loop, inline dosing, or point-of-foam generation.
Performance & grade selection
Silicone-free defoamers typically trade off between immediate foam knockdown and longer-term persistence. We select based on your foam type, shear environment, and sensitivity to surface defects.
Fast knockdown
Best for sudden foam spikes and high-foam events. Often used where foam causes overflow or disrupts level sensors.
Persistence
Best where foam continuously regenerates (recirculation, aeration, strong surfactant systems). Lower dosing frequency.
Air-release
Targets entrained air and microfoam—helps improve clarity, filtration, and appearance in water-based products.
Compatibility window
Selected to avoid destabilizing emulsions, reducing gloss, or creating haze. The “best” defoamer is system-specific.
Application method
Batch add, premix, or inline dosing. Addition point is critical—same product can behave differently by dosing location.
Cost-in-use
We quote with a cost-in-use mindset: dosage range + persistence typically matter more than price per kg.
Note: Final dosage and suitability must be validated on-site. Share your current additive and pain points; we’ll propose a trial plan.
Technical details
Typical ranges below support engineering review. Exact values depend on the selected grade. Request a TDS for the specification aligned to your process.
Type
Silicone-free antifoam / defoamer (water-based or oil-based carriers depending on grade)
Primary use
Foam suppression + entrained air reduction in aqueous industrial systems
Form
Liquid; some grades may be emulsions/solutions (grade dependent)
Typical property ranges (by grade)
Indicative only. Your quotation will specify the actual grade values.
| Property | Typical range | Why it matters |
|---|---|---|
| Appearance | Liquid (clear to opaque, grade dependent) | Indicates carrier system and handling behavior |
| Active content | Grade dependent | Impacts dosage and cost-in-use |
| Density @ 20 °C | ~0.90–1.10 g/cm³ | Relevant for dosing calibration and logistics |
| Viscosity | Low to medium (grade dependent) | Affects pumpability and dispersion in cold environments |
| pH (if water-based) | Grade dependent | Compatibility with alkaline/neutral/acidic systems |
| Performance focus | Knockdown / persistence / air-release | Matched to foam type and shear conditions |
| Silicone content | Silicone-free (by specification) | Reduces risk of silicone-related defects/contamination |
Engineering note: for sensitive coatings/adhesives, we recommend trialing at multiple addition points and confirming no impact on gloss, haze, or adhesion.
Typical dosage guidance
Dosage is system-dependent. We typically propose a starting range and then tune based on foam severity, shear, and persistence requirement. Share your current dosing and observed foam behavior for faster optimization.
Addition point
Many foam issues are solved by dosing at the foam-generation zone rather than at the tank. Inline dosing can reduce total consumption in continuous systems.
Handling & storage
Store sealed, protect from extreme temperatures, and mix/shake if specified on the TDS (grade dependent). We provide storage notes with the documentation package.
Typical specifications & formats
Values depend on grade and customer requirements. Confirm details on quotation. We will align the correct defoamer type (silicone-free) to your foam profile, system chemistry, and operating conditions.

FAQ
Quick answers for engineering and procurement review.
Why silicone-free?
Silicone can cause fisheyes/craters and adhesion issues in coatings and can create contamination concerns in silicone-sensitive operations. Silicone-free options reduce that risk while still providing effective foam control.
Will it affect my emulsion stability?
Some defoamers can destabilize emulsions or change haze/clarity. Grade selection and addition point matter. We recommend a controlled trial at multiple dosing levels to confirm compatibility.
Is it for knockdown or persistence?
Both options exist. Some grades are optimized for rapid knockdown; others are designed for longer persistence and air-release in continuous systems.
How do I choose dosage?
Dosage depends on foam severity, surfactants, shear, and temperature. Share your system details and current additive; we’ll propose a starting range and optimization plan.
What documentation can you provide?
SDS and TDS are available for engineering/QA review; COA can be supplied on request for delivered batches (by lane).
What packaging is available?
Common formats include drums and IBCs, with bulk options where applicable. Packaging depends on lane, grade, and destination.
Need a fast recommendation?
Share: (1) your system type, (2) pH, (3) key surfactants/dispersants (if shareable), (4) temperature, (5) foam description, and (6) where foam forms. We’ll propose a silicone-free grade and a trial plan.
