Specific Gravity (25℃)	0.90-0.95 g/cm³	Excellent compatibility with water-based systems

III. Core Advantages

Highly Effective Defoaming and Foam-Inhibiting Capability:The synergistic effect of modified silica and mineral oil enables rapid elimination of existing foam and long-term prevention of foam regrowth, making it ideal for continuous production of high-viscosity water-based systems.
Excellent Water Dispersibility:It disperses quickly in water to form a stable system without complex preprocessing, reducing local defects (e.g., craters, pinholes) caused by uneven dispersion.
Broad Compatibility:It exhibits good compatibility with various water-based resins, pigments, and additives, without affecting key properties such as gloss and adhesion of the system. Suitable for scenarios requiring high-quality finished product appearance.

IV. Application Fields

Core applicable systems: High-quality latex paints, architectural coatings (interior/exterior walls, floor paints), water-based adhesives (pressure-sensitive adhesives, white latex), latex products, water-based inks (packaging printing, flexographic printing), etc.
Highly recommended for: Production of high-end water-based products with strict requirements for defoaming efficiency and system transparency.

V. Usage Guidelines

Recommended Dosage: 0.1%-0.5% of the total formula, adjustable based on foam severity (not exceeding 1.0% in extreme cases).
Addition Timing:
- Grinding stage: Add 30%-50% of the total dosage to suppress foam generated during pigment dispersion;
- Paint mixing/final product stage: Add the remaining amount to enhance defoaming effect and prevent new foam from stirring or filling processes.

VI. Storage and Safety

Storage Requirements: Store in a cool, ventilated area at 5℃-35℃, away from heat sources and open flames. Keep containers sealed. Shelf life is 12 months.
Safety Notes: Wear protective gloves during operation to avoid direct skin contact. In case of eye contact, rinse immediately with water and seek medical attention. Refer to the Material Safety Data Sheet (MSDS) before use.
