INVINO® Defoamers for Cementitious Systems & Dry-Mix Mortars
Air and bubble control matters in cementitious systems — ready-mix concrete, pre-cast, dry-mix mortars, self-leveling underlayments, and grouts. Air entrained during mixing lowers compressive strength and density and spoils the surface of the cured product.
INVINO® supplies liquid concrete defoamers and free-flowing cement antifoam powders that control air voids, improve workability, and protect strength. For the full range across other binders, see our Construction Industry Defoamers overview.

Key Challenges in Cement & Concrete Formulation
Ordinary additives separate or float as oil slicks in liquid admixture tanks. Our modified polyether and silicone grades stay phase-stable in high-concentration PCE mother liquor.
Macro-bubbles above ~1 mm lower concrete strength. Our defoamers collapse them fast while keeping the fine air-void system needed for freeze-thaw durability.
Bubbles trapped against formwork cause honeycombing and surface voids. Fast bubble release gives a dense, smooth cast surface.
Defoamer Selection Matrix for Formulators
| PRODUCT CODE | FORM / CHEMICAL TYPE | Application / Best For | KEY PERFORMANCE | TECHNICAL FILES |
|---|---|---|---|---|
| INVINO-8061 | Modified Polyether (Liquid) | Cement fiber boards & cementitious slurry | Ruptures slurry bubbles in automated fiber lines; prevents internal voids and board delamination. | DOWNLOAD TDS |
| INVINO-8082 | Polyether Ester (Liquid) | Cement products & ready-mix concrete | Holds cured compressive strength; alkali-stable with no oil-slick separation. | DOWNLOAD TDS |
| INVINO-2501 | Silicone Powder (Solid) | Cementitious dry-mix mortars, tile adhesive, self-leveling | Free-flowing; dissolves on water addition; removes macro-bubbles in tile adhesives and self-leveling mortars. | DOWNLOAD TDS |
Technical FAQ for Cement & Mortar Formulators
Q: Will the defoamer lower the compressive strength of concrete?
A: No. It collapses the harmful macro-bubbles (above ~1 mm) that weaken concrete while leaving the fine air-void system needed for freeze-thaw durability, so compressive strength is protected.
Q: Is there a powder defoamer for dry-mix mortar?
A: Yes. INVINO-2501 is a free-flowing silicone powder that blends evenly with dry-mix mortar, tile adhesive, and self-leveling cement, then dissolves and works on water addition.
Q: Is the defoamer stable in liquid PCE admixtures over time?
A: Yes. The modified polyether (8061) and polyether ester (8082) grades stay phase-stable in high-concentration PCE mother liquor without oiling out or floating over long storage.
Q: Which grade for fiber cement board vs. ready-mix vs. dry-mix?
A: Use INVINO-8061 for fiber cement board and cementitious slurry, INVINO-8082 polyether ester for cement products and ready-mix, and INVINO-2501 powder for dry-mix mortar and tile adhesive.
Q: Does it cause surface bug holes or honeycombing?
A: No — it prevents them. By speeding bubble release against the formwork, it gives a dense, smooth cast surface and avoids honeycombing and bug holes.
