Octadecyl Polyoxyethylene Ether AC-1812 (also known as Leveling Agent AC-1812, Antistatic Agent AC-1812) is managed as a general chemical. The product appears as a light yellow to yellow paste or viscous liquid. Proper storage is crucial for maintaining product performance - this product has good thermal stability and resistance to acids and alkalis, but improper storage conditions may still lead to moisture absorption, deterioration, or performance degradation.
The product exhibits cationic characteristics under acidic conditions, and the polyoxyethylene chain segments in its molecular structure have certain hygroscopicity. Therefore, it should be immediately resealed after opening to prevent moisture absorption or contamination with impurities. The storage area should be clearly labeled with chemical identifiers, equipped with leakage emergency collection devices and appropriate fire-fighting equipment, and inspected regularly.
| Storage Requirement | Specific Description |
|---|---|
| Temperature Control | Maintain warehouse temperature below 35°C, avoid drastic temperature fluctuations |
| Environmental Requirement | Cool, dry, well-ventilated dedicated warehouse |
| Light Requirement | Keep away from ignition sources, heat sources, and direct sunlight |
| Package Sealing | Containers must remain sealed; reseal immediately after opening |
| Isolated Storage | Store strictly separately from oxidizers, acids, alkalis, flammable items, and food or feed |
| Shelf Life | Under original sealed conditions meeting the above storage requirements, the shelf life is two years from the date of production |
It is recommended to check the product appearance (light yellow to yellow paste or viscous liquid) before use. If there is abnormal discoloration, separation, or odor, discontinue use. For long-term stored products, it is advisable to use them up within a reasonable period after opening to avoid moisture absorption and contamination caused by repeated opening. If the product is in paste form, it can be moderately heated before use for easier handling, but the heating temperature should not be too high.
