Powder Defoamer — Solid Silicone Antifoam for Dry-Mix Construction, Detergents & Agrochemicals | INVINO®
Free-Flowing Solid Antifoaming Agent — No Liquid Carrier, Cold-Water Dispersible, Direct Dry-Mix Compatible
INVINO® powder defoamers are solid-form silicone antifoaming agents where active PDMS (polydimethylsiloxane) is absorbed onto a free-flowing inorganic carrier — precipitated silica, zeolite, or sodium sulfate. Unlike liquid emulsion defoamers, powder defoamers contain no water or liquid carrier, making them the only suitable antifoam format for dry-mix systems: cementitious mortars, tile adhesives, and self-leveling compounds; laundry detergent powders; and agrochemical wettable powders (WP) and water-dispersible granules (WDG).
Key performance characteristics: cold-water dispersible — releases active silicone uniformly when water is added, no clumping; stable in high-alkali environments — maintains defoaming activity across the full pH range of cementitious systems; and precise dosing control — solid format allows accurate weighing and blending directly into dry-mix aggregate components. Dosage typically 0.05%–0.5% by total dry weight depending on application.

| INVINO-2501 | White free-flowing solid | 20.0–30.0 | 6.0–8.0 | Dry-mix cementitious mortar, tile adhesive, self-leveling flooring compounds, and building external insulation grout. Added during dry blending stage before water addition. |
| INVINO-2502 | White free-flowing solid | 20.0–30.0 | 6.0–8.0 | Agrochemical wettable powders (WP) and water-dispersible granules (WDG). Controls foam during spray tank mixing and formulation processing without affecting pesticide efficacy. |
Key Applications for Solid Powder Defoamers
Powder defoamers are the only antifoam format compatible with dry-mix and solid-phase systems — no liquid carrier, no premixing required.
Dry-Mix Construction Materials
Added directly to dry aggregate blends for cementitious mortar, tile adhesive, self-leveling compounds, and external insulation grout. Prevents air voids that reduce compressive strength and surface finish quality. Grade: INVINO-2501.

Q. What is a powder defoamer and how is it different from liquid defoamers?
A powder defoamer is a solid antifoaming agent where active silicone (PDMS) is absorbed onto a free-flowing inorganic carrier such as precipitated silica, zeolite, or sodium sulfate. Unlike liquid emulsion defoamers, powder defoamers contain no water or liquid carrier — making them the only suitable antifoam format for dry-mix systems such as cementitious mortar, detergent powders, and agrochemical WP/WDG formulations where liquid additives would cause clumping or premature activation.
Q. How do I incorporate powder defoamer into dry-mix construction materials?
Add the powder defoamer directly to the dry aggregate components during the dry mixing stage, before water addition. Blend thoroughly to ensure uniform distribution throughout the mix. Standard dosage is 0.05%–0.3% by total dry weight. The defoamer activates automatically when water is added — no pre-dispersing required. For liquid processing systems, pre-disperse in a small volume of water before adding to the main mix.
Q. Does INVINO powder defoamer disperse in cold water?
Yes. INVINO powder defoamers use water-soluble inorganic carriers that dissolve rapidly in cold water, releasing the active silicone component evenly without clumping or residue. This makes them suitable for winter construction work and cold-water mixing conditions — an advantage over some powder defoamers that require warm water to fully activate.
Q. Will powder defoamer affect concrete compressive strength?
No — within standard dosage ranges (0.05%–0.3% by dry weight), powder defoamers eliminate excessive entrained air without over-deaerating the mix. Controlled air content improves concrete density and compressive strength. Note: excessive overdosing should be avoided, as very low air content can reduce freeze-thaw resistance in some concrete formulations.
Q. What are the main industrial applications for solid powder defoamers?
Powder defoamers are used wherever a liquid-free antifoam is required: dry-mix cementitious mortar and construction materials (INVINO-2501); laundry detergent powder and industrial cleaning powders (INVINO-2000); agrochemical wettable powders (WP) and water-dispersible granules (WDG) (INVINO-2502); and spray-dried chemical formulations requiring solid-phase foam control.
Q. How do I prevent powder defoamer from caking during storage?
Store in original sealed bags in a cool, dry, well-ventilated warehouse at 5–35°C. Keep bags on pallets off the floor, avoid stacking too high, and protect from direct sunlight and moisture. Reseal opened bags immediately. Properly stored INVINO powder defoamers maintain free-flowing properties for 12 months. If minor caking occurs, break up mechanically before use — performance is not affected.

Grade Selection
Match your application to the correct grade: INVINO-2000 for laundry detergent and cleaning powder formulations; INVINO-2501 for dry-mix cementitious mortar, tile adhesive, and construction materials; INVINO-2502 for agrochemical WP and WDG formulations.
Integration Method
For dry-mix systems: add during the dry blending stage before water addition. Ensure thorough mixing for uniform distribution. Run a small bench trial with your actual dry-mix formula before full production scale-up — test for foam control performance, compressive strength (for mortar), and compatibility with your other additives.
Dosage Reference
Construction dry-mix: 0.05%–0.3% by total dry weight.
Laundry detergent: 0.05%–0.2% by total formulation weight.
Agrochemical WP/WDG: 0.1%–0.5% by formulation weight.
Start at the lower end and increase if foam persists. Contact our engineers if you need dosage verification before scale-up.
