What are the storage conditions for papermaking defoamer XS-02, a polyether ester defoamer?

Papermaking defoamer XS-02 should be stored in a sealed container in a cool, dry, and dark place. The recommended storage temperature is 5~35°C.

Detailed Description

Papermaking defoamer XS-02 (polyether ester defoamer) is a nonionic surfactant product. During storage, it is necessary to avoid environmental factors that may adversely affect product performance. The container must be kept sealed to prevent contact with moisture or impurities in the air, and to avoid volatilization or oxidative deterioration of the product.

The storage environment should be a cool, dry, and dark place. The recommended storage temperature should be strictly controlled within the range of 5~35°C. Too low a temperature may cause the product to become viscous or even solidify, affecting its dispersibility during use; too high a temperature may accelerate product aging and shorten its effective service life. In addition, it must be kept away from heat sources, sparks, open flames, and strong oxidizers. Although this product is non-flammable (closed-cup flash point >150°C), keeping it away from ignition sources is a basic safety requirement for chemical product storage.

If the product requires dry storage, direct contact with water or moisture should be avoided. The floor of the storage area should be chemical-resistant and equipped with spill prevention measures (such as spill containment trays or dikes) to handle accidental container breakage or other emergencies, preventing leakage from contaminating soil and water bodies.

Technical Parameters

Application Suggestions

• Usage specification: Seal the container immediately after each use to reduce product exposure to air, preventing moisture absorption or contamination.
• First-in, first-out: It is recommended to follow the "first-in, first-out" inventory management principle, prioritizing the use of earlier batches within the shelf life to ensure stable performance.
• Repackaging precautions: If repackaging is needed, the repackaging container should also be kept clean, dry, and chemical-resistant, and sealed after repackaging.

Notes

• Do not store at temperatures outside the 5~35°C range for extended periods. If the product freezes or stratifies due to low temperature, allow it to naturally warm to room temperature and stir evenly before use; do not heat directly.
• Prominent safety signs should be placed in the storage area, and unauthorized personnel should not enter.
• Dispose of waste packaging in accordance with local environmental regulations; do not discard arbitrarily.
• In case of a spill, use inert absorbent materials (e.g., sand, vermiculite) for small amounts; for large spills, dike and contain the leakage and transfer to recovery containers, preventing entry into drains and water bodies.
