Polyether L-63 is a non-hazardous substance with a high flash point (closed cup flash point >200°C). It is a non-flammable liquid with relatively high storage safety. However, standard chemical product storage management requirements should still be followed to ensure product quality stability and avoid moisture absorption, deterioration, or contamination due to improper storage. Under recommended storage conditions, the product should be used within the specified shelf life. After long-term storage, it is recommended to sample and test to confirm compliance before use.
This product should be stored in a dedicated warehouse or area, away from heat sources, sparks, open flames, and incompatible substances such as strong oxidizers and strong acids. The storage area should be kept clean, avoid accumulation of leaks, and be equipped with necessary spill containment facilities. Do not store together with food, feed, or pharmaceuticals to prevent cross-contamination.
| Storage Requirement | Specific Description |
|---|---|
| Environmental conditions | Cool, dry, well-ventilated dedicated warehouse or area |
| Recommended temperature | 5–40°C, avoid freezing or prolonged exposure to high temperature |
| Container requirements | Keep container tightly sealed; containers made of carbon steel, stainless steel, or specific plastics can be used |
| Substances to avoid | Heat sources, sparks, open flames, strong oxidizers, strong acids |
| Compatibility | Do not store together with food, feed, or pharmaceuticals |
| Handling after opening | Seal properly to prevent moisture absorption or contamination |
Polyether L-63 has strong hygroscopicity. After opening the drum, use as soon as possible and seal promptly to avoid prolonged exposure to humid air that may cause water absorption. If the product shows increased viscosity or slight turbidity at low temperatures, it can be placed in a warm environment to slowly warm up to room temperature and then stirred evenly. This usually does not affect performance. For bulk long-term storage, it is recommended to periodically sample and test key indicators such as moisture content and hydroxyl value to ensure quality meets usage requirements.
