XRT-DA Concrete Polyether Defoamer is a professional high-carbon-alcohol polyether ester defoamer formulated for concrete admixtures, widely used with polycarboxylate superplasticizers.
It removes harmful, uneven bubbles while retaining helpful air bubbles to extend concrete service life. Tested and used on construction sites, this concrete defoamer optimizes pore structure, boosts compressive strength, and maintains stable slump with no impact on performance.
Our special formula features good dilution stability and strong alkali resistance. It defoams quickly and provides long-lasting foam control.
Anti-foaming agent Key FeaturesIt removes big, unstable bubbles and keeps the tiny bubbles from the air
entraining agents.
It makes the concrete denser and improves its pore structure, so it becomes
stronger and lasts longer.
Mixes perfectly with polycarboxylate superplasticizers to form a stable blend.
Works well in concrete's strong alkaline environment (pH > 12).
Mixes easily with water. No separation or oil floating; keeps well blended.

1. Is it compatible with polycarboxylate superplasticizers?
Yes. It mixes perfectly with polycarboxylate superplasticizers, causing no delamination or oil separation and causing no performance loss.
2. Does it adapt to high-alkali concrete?
Yes. It features excellent alkali resistance, working stably in concrete with pH above 12 and enduring high-temperature alkaline conditions.
3. Does water dilution cause separation?
No. It is easily water-dilutable, with no breaking, delamination, or oil floating, resulting in even dispersion in concrete slurry.
4. What is its core advantage? Does it weaken concrete strength?
It realizes selective defoaming, removing harmful large bubbles and retaining useful microbubbles. It optimizes concrete pore structure, improves strength and durability, and stabilizes slump.
5. Will it lead to concrete slump loss?
No. Field-proven stable performance ensures effective defoaming without causing slump loss of concrete.
ConclusionControlling bleeding in concrete made with polycarboxylate superplasticizer is a comprehensive process involving several factors. These include:※ Customized design of the polycarboxylate water reducers’s molecular structure※ Proper use of air-entraining agents and viscosity-modifying admix
At a GlanceDispersion effect: Anionic carboxylic groups adsorb onto positively charged cement particles, creating electrostatic repulsion that breaks down flocculated cement structures and releases entrapped mixing water.Lubricating effect: Extended hydrophilic polyoxyethylene side chains form a den
Sodium Naphthalene Sulfonate (SNF) based admixtures are widely used as high-range water reducers in modern concrete production. By improving cement particle dispersion, SNF helps reduce water demand by around 18% to 28% while maintaining good workability and strength development. Its unique chemical
Global ocean freight keeps rising, with South America routes hit hardest. Traditional liquid PCE superplasticizer only has 40‑50% solid content. Water fills much of the container space, driving up logistics costs and increasing the risk of performance degradation during long‑distance hot sea transport. This article covers three main PCE forms: liquid, powder, and flake, and highlights the merits of flake or powder PCE superplasticizer. Cost simulation based on a 40'GP container shows that high‑solid solid‑form PCE greatly reduces freight cost per ton of active substance. With stable performance, long shelf life, low storage requirements, and good compatibility with ready‑mix concrete and dry mortar, it is a preferred cost‑saving solution for concrete admixture importers and distributors amid surging ocean freight.
