Defoamer King FAG470 is a polyether modified polysiloxane emulsion defoamer, and its storage conditions directly affect the stability and effectiveness of the product. According to the product safety data sheet, although this product is not a hazardous chemical, proper storage is essential to maintain defoaming performance. The product should be stored in the original sealed container to avoid prolonged contact with air that may cause water evaporation or surface skinning.
This product is sensitive to temperature, and the storage temperature must be strictly controlled between 5℃ and 40℃. Below 5℃ may cause emulsion freezing and demulsification, leading to separation of active ingredients; even if the temperature is restored, it is difficult to recover. Continuous heating above 40℃ will accelerate emulsion aging, resulting in viscosity changes and reduced defoaming efficiency. In addition, it should be kept away from incompatible substances such as strong oxidizers, strong acids, and strong bases to prevent chemical reactions that affect product quality.
Regarding the shelf life, the product database does not specify a specific duration. According to industry practice for similar polyether modified silicone defoamer products from Guoli Chemical, subject to strict compliance with storage conditions and unopened original containers, it is recommended to use within 12 months. Once opened, the product should be used as soon as possible to avoid prolonged exposure to air that may introduce impurities or microbial growth, leading to product deterioration.
| Storage element | Specific requirements |
|---|---|
| Storage temperature | 5℃～40℃, strictly avoid freezing or sustained high temperature |
| Environmental requirements | Cool, dry, well-ventilated, avoid direct sunlight and heat radiation |
| Container status | Keep sealed to prevent moisture absorption, evaporation, or external contamination |
| Storage method | Keep away from incompatible substances such as strong oxidizers, strong acids, strong bases, store separately |
| Warehouse facilities | Equip with leakage collection tools, keep floor clean to prevent slipping |
| Shelf life | No official data (industry suggestion: use within 12 months if unopened) |
If slight stratification occurs after long-term storage, this is a normal phenomenon for emulsion-type products. Slight stirring to uniformity can restore performance without affecting defoaming effect. If stirring fails to restore uniformity, or if obvious odor, discoloration, or severe stratification occurs, the product may have deteriorated and should not be used. It is recommended to establish a first-in, first-out inventory management system and regularly check the status of stored products.
