Commercial fit
For producers who need stable foam control, consistent batches, and documentation aligned to procurement.
Product Construction Chemicals
Silicone Defoamer Emulsion
High-efficiency silicone antifoam emulsion for foam control in construction chemical production and on-site application. Designed for fast foam knockdown and long-lasting suppression under shear.
Packaging: drums / IBC / bulk (as applicable)
Documentation: SDS / COA / TDS on request
Lane options: spot supply • repeat procurement • contract lots
Performance intent
Fast knockdown + persistent defoaming to improve throughput, surface quality, and pack stability.
Grade selection
Matched by system (cementitious / polymer), shear profile, temperature, and air-content targets.
Note: silicone defoamer selection is formulation-dependent. We align the right emulsion system based on your binder, surfactant package, and process conditions.
Why foam control matters in construction chemistry
Foam is not just a visual problem — it reduces effective filling speed, disrupts dosing accuracy, can increase entrained air, and may leave pinholes, craters, or reduced strength in cementitious and polymer-modified systems.
Production efficiency
Less tank foam and faster filling reduce downtime, losses, and rework.
Quality consistency
Controls entrained air and surface defects for stable product appearance and performance.
Application finish
Improves wet film leveling and reduces micro-foam during mixing and spreading.
How silicone emulsions work
Silicone defoamers typically act by destabilizing foam lamellae and accelerating bubble coalescence and collapse. Emulsion design (silicone phase, emulsifier system, particle size distribution) influences knockdown speed, persistence, and compatibility with surfactant-rich formulations.
Applications
Typical usage patterns. Tell us your process and constraints and we’ll align the right specification.
Where it is commonly used
- Foam control in concrete admixture production (mixing, transfer, filling)
- Defoaming in polymer-modified mortars (tile adhesives, renders, grouts)
- Self-leveling underlayments (micro-foam reduction for smooth finish)
- Waterproofing / coating systems (pinholes & crater mitigation)
- Process foam reduction in high-shear dispersion steps
Typical performance goals
Knockdown
Rapid collapse of surface foam during mixing and filling.
Persistence
Continued suppression under agitation, pumping, and recirculation.
Surface quality
Lower micro-foam → fewer pinholes, craters, and surface defects.
Typical specifications & formats
Values depend on grade and customer requirements. Confirm details on quotation. If you share the system and performance targets, we will align a suitable emulsion design.

Notes
Dose depends on foam severity, shear, and surfactant load
Practical guidance (typical)
Use this as a starting point for plant or lab trials.
Dosage starting point
Often 0.05–0.30% on total formulation (or 0.1–1.0% on binder), depending on system.
Addition points
Dispersion step, let-down, or in-line dosing. Aim for early control without overdosing.
Trial evaluation
Track foam height/decay, entrained air, surface pinholes, and final mechanical properties.
Important: overdosing any defoamer may cause surface defects (e.g., fisheyes) or reduced film clarity in some coating systems. Screen compatibility and appearance before scale-up.
Compatibility & selection guide
Defoamer performance is strongly influenced by your formulation’s surfactant package, polymer type, salts, fillers, and mixing energy. We typically shortlist grades by where foam forms and what failure mode you are trying to prevent.
Common systems we align for
- PCE-based concrete admixtures (slump retention / air content sensitivity)
- Acrylic / SBR / VAE latex-modified mortars (foam during mixing and application)
- Cellulose ether thickened systems (higher foam stability)
- Waterproofing dispersions and cement-polymer hybrids (pinholes/craters)
What we optimize for
Air management
Balance foam reduction without destabilizing required air entrainment (when applicable).
Process stability
Stable performance across temperature, shear, storage, and packaging conditions.
Appearance
Minimize surface defects and maintain uniform dispersion at target dosage.
Handling, storage & safety
General handling guidance. Always follow your site procedures and the supplied SDS.
Storage
Typically store in sealed original packaging, protected from freezing and excessive heat. Avoid prolonged exposure to direct sunlight.
Shelf life
Often 6–12 months (grade- and storage-dependent). Confirm on COA/TDS for the supplied batch.
Mixing before use
Emulsions may settle over time. Gentle homogenization is commonly recommended before dosing.
Compatibility testing
Always run a lab/plant trial at your intended dosage and addition point before full-scale production.
Regulatory / transport
Many emulsions ship as non-hazardous; classification depends on grade. Confirm using the batch SDS.
Waste & cleaning
Follow local regulations and SDS guidance. Clean dosing lines promptly to avoid residue build-up.
Disclaimer: values and handling notes are typical guidance only. Final parameters and regulatory status are confirmed in the SDS/TDS for the quoted grade and supplied batch.

FAQ
Quick answers to common procurement and formulation questions.
Do you supply multiple activity levels?
Yes — silicone content/activity can vary by grade. We align activity and emulsifier system to your foam profile and dosing preference.
Can it be used in cementitious systems?
Commonly, yes. Compatibility depends on polymer modifiers, surfactants, and air control requirements. A short trial is recommended.
What about temperature and shear?
Emulsion stability and defoaming persistence depend on temperature and shear. Share your process conditions so we can shortlist appropriately.
How do you prevent overdosing issues?
Start low, test addition points, and evaluate surface appearance. We can suggest a dosing window and screening plan based on your system.
Can you provide SDS/COA/TDS?
SDS and batch COA are available on request; TDS is typically provided for the quoted grade.
What packaging is available?
Commonly drums and IBCs; bulk may be available depending on lane, origin, and volume.
