Defoamer King FAG470 is a polyether-modified polysiloxane non-ionic defoamer, provided in aqueous emulsion form. It features fast defoaming speed, long-lasting foam suppression, and excellent resistance to high temperature and strong alkali. Its non-hazardous chemical nature makes daily use relatively low in safety risk, but as an industrial chemical, basic operating specifications must still be followed. Before use, lightly stir to homogenize the product. It can be added directly or after dilution with several times the amount of water. It is recommended to continuously add it to the foam-generating area using a metering pump for optimal defoaming and foam suppression effects. The specific dosage should be determined through small-scale tests based on actual working conditions and foam levels, avoiding excessive use that may cause waste or affect system performance.
During actual operation, ensure good ventilation conditions and wear personal protective equipment such as protective gloves and safety glasses. Avoid contact with eyes, mucous membranes, and prolonged skin contact. Wash hands and other potentially contaminated areas promptly after handling. Handle the product with care to avoid splashing or generating excessive mist. Although the product is non-flammable, it may decompose and produce harmful fumes when heated in a fire. Firefighters should use self-contained breathing apparatus and full protective clothing for disposal.
Proper storage is crucial for maintaining product stability. It is recommended to store the product in a cool, dry, and well-ventilated warehouse, away from direct sunlight and heat sources. The container should always be kept sealed to prevent moisture absorption, evaporation, or external contamination. The storage temperature must be strictly controlled within the range of 5°C to 40°C, with special attention to preventing freezing or prolonged high temperatures, as these may affect the emulsion stability and defoaming performance of the product. Keep the product away from incompatible substances such as strong oxidizers, strong acids, and strong alkalis, and store separately. After opening, use the product as soon as possible; reseal any unused portion.
| Type of Contact | Treatment Method |
|---|---|
| Inhalation | Move the person to fresh air and keep the airway clear; if discomfort occurs, seek medical attention promptly. |
| Skin Contact | Immediately remove contaminated clothing and wash the affected area with plenty of water and soap; if irritation or discomfort develops, seek medical help. |
| Eye Contact | Immediately flush thoroughly with plenty of running water or saline for at least 15 minutes, lifting the eyelids to ensure adequate rinsing; if discomfort persists, seek medical attention immediately. |
| Ingestion | Rinse mouth with water, do not induce vomiting (unless instructed by a professional); immediately bring the product label and SDS for medical attention. |
| Spill Handling | Stop the source of the leak, contain with inert absorbent material (e.g., sand, vermiculite), and collect in a dedicated container for disposal according to local regulations; avoid discharging into drains or waterways. |
| Fire | Use water spray, foam, dry powder, or carbon dioxide extinguishing agents; extinguish based on the nature of surrounding fire sources; firefighters must wear self-contained breathing apparatus and full protective clothing. |
