I. Basic Information

• Product Type: Defoamer
• Brand & Model: Vinapor DF9010F
• Core Ingredient: Fatty Alcohol, a highly active component purified through a special process, featuring excellent surface activity and foam-inhibiting capabilities, suitable for the chemical environment of cement-based and concrete systems.
• Packaging Specification: 25 kg/package, packed in moisture-proof woven bags lined with PE film. This packaging effectively blocks moisture and air, facilitating transportation and storage, and is suitable for bulk use in small and medium-sized projects.

II. Core Features

1. Specialized Compatibility with Cement-Based SystemsDesigned for alkaline substrates such as cement and concrete, it can withstand high pH environments (12-14) without adverse reactions with cement hydration products. In systems like grouting materials and self-leveling cement, it can quickly eliminate air bubbles mixed in during stirring and foam generated by chemical reactions, avoiding issues such as increased material porosity and reduced strength caused by foam.

2. Dual Efficacy of Efficient Foam Breaking and Long-Term Foam Inhibition

• Instant Foam Breaking: The fatty alcohol component can rapidly reduce the surface tension of cement paste, destroying the stability of foam films. It achieves rapid defoaming during the stirring stage (e.g., when preparing self-leveling cement), ensuring uniform fluidity of the paste.
• Long-Term Foam Inhibition: By forming a micromolecular protective film during the cement hardening process, it continuously inhibits foam generated due to water evaporation or gas escape in the later curing stage, ensuring the compactness of the hardened structure (e.g., reducing honeycombs and pockmarks on the concrete surface).

3. Low Dosage and Performance EnhancementThe conventional dosage is only 0.05%-0.2% of the mass of cement-based materials to achieve the ideal defoaming effect. After addition, it does not affect the cement setting time, fluidity, or final strength; instead, it can improve the material's compressive strength (test data shows that when 0.1% is added, the 28-day strength of self-leveling cement can increase by 5%-8%) and impermeability by reducing porosity. It is particularly suitable for engineering scenarios with high strength requirements (e.g., bridge grouting, industrial floors).

4. Optimized Construction CompatibilityIt is compatible with construction processes such as pumping, troweling, and pouring. It will not cause defects like color differences or honeycombs on the surface of cement products due to uneven dispersion of the defoamer. In self-leveling cement, it can improve the paste's leveling property, ensuring that the floor flatness error is ≤2mm/3m, meeting the construction requirements of high-specification floors.

III. Application Fields

IV. Usage Recommendations

1. Addition Timing

• It is recommended to add it at the initial stage of water addition and stirring of cement-based materials, mixing it with cement and aggregates simultaneously to ensure uniform dispersion of the defoamer. For concrete, it can be mixed into the aggregate and cement during the dry mixing stage before adding water for stirring.
• For finished materials such as ready-mixed mortar, the "post-addition method" (diluting with a small amount of water and adding slowly) can be adopted to avoid affecting the storage stability of the material.

2. Recommended Dosage

• Grouting materials/self-leveling cement: 0.1%-0.2% (based on the mass of cement);
• Concrete: 0.05%-0.1% (based on the mass of cementitious materials);
• Before the first use, a trial mix is required to determine the optimal dosage (e.g., preparing 10kg of cement paste to test the defoaming effect and strength impact of different dosages).

3. Operation PrecautionsMaintain a stirring speed of 150-300rpm when adding to avoid emulsification failure of the defoamer due to high-speed shearing. If used together with other admixtures (e.g., water reducers, expansive agents), it is recommended to add the defoamer first and stir for 2-3 minutes before adding other components to prevent mutual interference between components.

V. Storage and Safety

• Storage Conditions: Store in a dry and well-ventilated place at 5-35℃, avoiding moisture or direct sunlight. The shelf life is 12 months in the unopened state; after opening, seal the bag mouth and use it up within 3 months.
• Safety Tips: Wear protective gloves during operation to avoid direct skin contact. If it accidentally gets into the eyes, rinse immediately with water for 15 minutes and seek medical attention. This product is not a dangerous good and should be handled as an ordinary chemical raw material during transportation. For details, refer to the MSDS Safety Data Sheet.
