Polyether defoamer for sale high efficiency anti-foaming agent
Polyether defoamers are primarily synthesized from propylene glycol/glycerin, propylene oxide, ethylene oxide, etc., via potassium hydroxide-catalyzed reactions to form a highly effective defoaming solution. Characterized by environmental friendliness and high efficiency, this series is water-dilutable. Specifically developed for the cement concrete admixture industry—particularly for polycarboxylate superplasticizers—this defoamer is a novel high-carbon alcohol polyether ester formulation.
This high-temperature-resistant polyether defoamer is made from propylene glycol, glycerin, propylene oxide, and ethylene oxide, using potassium hydroxide as a catalyst. It delivers an excellent, long-lasting foam-inhibiting effect.
Eco-friendly and high-efficiency, this non-silicone antifoam agent can be mixed directly with water. Specially developed for concrete admixture, it offers excellent compatibility and perfectly complements polycarboxylate superplasticizers, serving as a premium modified higher-alcohol polyether ester defoamer for cement slurry and construction projects.
Usage Instructions
◆ Pre-use Preparation: Stir well before use, as sedimentation or stratification
May occur after long-term storage.
◆ Dosage: Add directly to the polycarboxylate superplasticizer at a
recommended dosage of 1–3‰ (based on the weight of the
superplasticizer). Mix thoroughly to form a homogeneous water-reducing
agent mixture.
◆ Application Tip: Stir the polycarboxylate superplasticizer for 20–50 seconds before use to ensure uniform dispersion.

Polyether defoamer (for concrete) — where it’s used
◆ Concrete admixtures
Mixes well with polycarboxylate, naphthalene, lignosulfonate, and other water-reducers to get rid of foam made
during production, mixing, and pumping.
◆ Cement paste/mortars
Useful for cement paste, plaster, masonry mortar, and self-leveling screeds to reduce air bubbles and make the mix denser.
◆ Precast products
Used in making precast concrete items like panels, pile sections, wall panels, and floor tiles.
◆ On-site construction
Works in ready-mix plants, cast-in-place concrete, grouts, grout injectables, and waterproof slurries.
◆ Related chemical systems: Can be used as a defoamer/foam suppressor in water-based building additives, paints, and other waterborne building emulsions.
Defoaming Agent Storage & Handling
Store in cool, dry conditions away from direct sunlight.
Agitate gently before each use to maintain consistency.
Avoid mixing with strong acids, bases, or incompatible chemical additives.
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.
