Storage Conditions
| Item | Requirements |
| Storage Temperature | 5–40°C. Indoor storage is recommended. Protect from freezing, as freezing may damage the polymer system. |
| Packaging & Container Requirements | Packaged in 200 L plastic drums with a net weight of 200 kg per drum; 25 kg plastic pails or 1,000 kg intermediate bulk containers (IBCs) may also be used. |
| Shelf Life | 2 years. After expiry, the product may only be used after it has been retested and confirmed to meet specifications. |
| Key Properties (KR9988) | Appearance: light yellow to pale red viscous liquid; pH (5% solution): 9.5–10.5; kinematic viscosity (10% solution at 40°C): 3.19 mm²/s. |
| Precautions | Nonflammable and presents no fire hazard; nevertheless, keep the container tightly sealed. If stored outdoors, place the drum horizontally to prevent water, dust, and other contaminants from entering. Retighten the cap immediately after dispensing. Check the concentration with a refractometer before use. PAG-containing products exhibit reverse solubility; polymer separation at elevated temperatures is normal, and the product can be restored by cooling and stirring. |
