Easy to Use: Concrete defoamers are easy to incorporate into the mix, with simple dosage guidelines. Whether in liquid or powder form, they can be added during the mixing process without the need for specialized equipment, making them convenient for both small and large-scale projects.

Long Shelf Life: These additives have a long shelf life, ensuring that they maintain their effectiveness even when stored for extended periods, making them ideal for long-term use on multiple projects.

Specifications of Silicone Based Antifoam Chemical Polydimethylsiloxane Concrete Defoaming Agent Factory

Product Specifications: Silicone-Based Antifoam for Concrete

Chemical Composition

This defoaming agent is made from polydimethylsiloxane (PDMS), a high-purity silicone oil. It additionally contains hydrophobic silica and a food-grade carrier fluid. The formula is without solvents, heavy steels, and unpredictable natural compounds (VOCs).

Physical Residences

The product looks like a milky white emulsion. It has a thickness of about 0.98– 1.02 g/cm three at 25 ° C. Thickness ranges from 500 to 1,500 cP. The pH value remains between 6.0 and 8.0 in a 10% water option. It remains stable under typical storage space conditions and does not separate or clear up promptly.

Efficiency Includes

Strong defoaming activity starts quickly after mixing into concrete or mortar. It damages existing foam and stops brand-new bubbles from creating. The agent works well across a large temperature array, from 5 ° C to 40 ° C. It keeps concrete blends smooth and regular without hurting strength or establishing time.

Dosage and Make use of

Add 0.05% to 0.3% by weight of complete cement content. Mix completely during batching. Dosage might vary based on mix design, water content, and kind of additives used. Always check a tiny set first to discover the very best amount for your application.

Applications of Silicone Based Antifoam Chemical Polydimethylsiloxane Concrete Defoaming Agent Factory

Applications of Silicone-Based Antifoam: Polydimethylsiloxane Concrete Defoaming Representative

Why Utilize This Defoaming Representative?

Air bubbles in concrete reason serious problems. They deteriorate the structure and reduce toughness. Our silicone-based antifoam, made from polydimethylsiloxane (PDMS), eliminates these unwanted bubbles quick and properly. It works well in lots of kinds of concrete blends.

Where It Is Made use of

This defoaming representative is perfect for precast concrete production. Manufacturing facilities use it to make smooth, thick surfaces on panels, pipelines, and blocks. Ready-mix concrete plants likewise include it to improve workability and finish. It aids during putting and resonance by breaking foam promptly. Self-consolidating concrete (SCC) advantages too. SCC needs reduced air material to flow appropriately without partition– our product guarantees that equilibrium.

How It Functions

The energetic component, polydimethylsiloxane, spreads conveniently through wet concrete. It decreases surface area tension at air-liquid user interfaces.
