I. Basic Information

• Product Type: Defoamer
• Brand & Model: Foamaster S2292 - Dehydran 1293
• Core Ingredient: Special Modified Polydimethylsiloxane Solution. Through a special chemical modification process, specific functional groups are introduced into the molecular structure of polydimethylsiloxane, enhancing its compatibility with water-based systems and defoaming activity.
• Packaging Specification: 180 kg/barrel. Packaged in high-quality metal barrels with anti-corrosion treatment on the barrel body and well-sealed lids. This design effectively prevents leakage and deterioration of the product during transportation and storage, facilitating industrial bulk use and storage.

II. Core Features

1. High Compatibility with Water-Based SystemsDeveloped specifically for water-based systems such as water-based coatings, water-based wood lacquers, and varnishes, it can disperse stably in high-polarity water-based environments. It does not react adversely with resins, pigments, additives, or other components in water-based systems, ensuring the chemical stability and physical properties of the system remain unaffected. It is particularly suitable for high-end water-based coating products with strict requirements for formula compatibility.

2. Efficient Rapid Foam Breaking and Long-Lasting Foam Inhibition

• Rapid Foam Breaking: The specially modified polydimethylsiloxane molecules can quickly spread on the foam surface, reducing the surface tension of the foam film and causing the foam to break rapidly. During foam-prone stages of coating production (e.g., stirring, grinding), it can eliminate foam in a short time, ensuring the smooth progress of the production process.
• Long-Lasting Foam Inhibition: During the drying and film-forming process of coatings, this defoamer can continuously inhibit the regeneration of foam. Even under harsh conditions such as high temperature and high humidity, it can effectively prevent foam generated by water evaporation, gas escape, or other factors, ensuring the coating surface is smooth and free of defects like pinholes and bubbles.

3. Low Dosage and Excellent Preservation of Coating PerformanceThe conventional dosage is only 0.05%–0.3% of the total system mass to achieve the ideal defoaming effect. After addition, it does not affect key coating properties of water-based coatings, such as gloss, transparency, adhesion, and hardness. When used in water-based wood lacquers, it ensures the clear display of wood grain while endowing the paint film with good wear resistance and water resistance; when used in varnishes, it does not reduce the high transparency and aesthetics of the varnish.

4. Friendly to Construction ProcessesIt has good adaptability to common coating application processes such as spraying, brushing, and roller coating. During spraying, it will not cause problems like poor atomization or sagging due to the addition of the defoamer; during brushing and roller coating, it can effectively prevent foam generated by air entrainment, making the coating more uniform and smooth, and improving construction efficiency and coating quality.

III. Application Fields

IV. Usage Recommendations

1. Addition TimingIt is recommended to add during the paint mixing stage of the coating formula—i.e., after the resin, pigments, fillers, and other components are mixed evenly, add the defoamer slowly and stir uniformly. If a large amount of foam has already formed during production, take a small amount of defoamer for local defoaming first, then supplement the addition according to the recommended dosage.

2. Recommended Dosage

• Water-based coatings: 0.1%–0.3% (of the total system mass);
• Water-based wood lacquers: 0.05%–0.2% (of the total system mass);
• Varnishes: 0.1%–0.2% (of the total system mass).Before first use, it is recommended to conduct a small-scale formula test to determine the optimal dosage, achieving a balance between the best defoaming effect and coating performance.

3. Operation PrecautionsWhen adding the defoamer, the stirring speed should not be too high (recommended to be controlled at 200–400 rpm) to avoid damaging the molecular structure of the defoamer due to high-speed shearing, which would affect the defoaming effect. If other additives are used simultaneously, pay attention to the addition sequence—avoid direct contact with strongly alkaline or strongly acidic additives, and it is recommended to add them at an interval of 15–30 minutes to prevent chemical reactions that cause additive failure.

V. Storage and Safety

• Storage Conditions: Store in a cool, dry, and well-ventilated place at 5–35℃, away from direct sunlight and high-temperature environments. The shelf life of unopened products is 12 months. After opening, use the product as soon as possible and seal the barrel tightly to prevent the product from absorbing moisture or being contaminated; it is recommended to use it up within 3–6 months.
• Safety Tips: It is recommended to wear protective gloves and goggles during operation to avoid contact between the product and skin or eyes. If it accidentally comes into contact with the skin, rinse immediately with plenty of water; if it comes into contact with the eyes, rinse immediately with plenty of water and seek medical attention. This product is not a hazardous chemical and should be transported and stored as an ordinary chemical product. For details, refer to the MSDS Safety Data Sheet.
