Octadecylamine Polyoxyethylene Ether AC-1820 should be stored sealed in a cool, dry, and well-ventilated environment. Under recommended storage conditions, the shelf life is typically 1-2 years from the date of manufacture.

Detailed Description

To ensure the stable quality and performance of Octadecylamine Polyoxyethylene Ether AC-1820, its storage requirements must be strictly followed. This product is slightly hygroscopic and has a melting point of approximately 35°C, so special attention must be paid to controlling the temperature and humidity of the storage environment. The product should always be stored in a sealed original container to avoid contact with moisture and impurities in the air. The storage area should be well-ventilated, away from heat sources and ignition sources, and protected from direct sunlight to prevent product discoloration or performance degradation.

In terms of compatibility, this product should be stored separately from incompatible substances such as strong oxidizing agents and strong acids to avoid harmful chemical reactions. It is recommended to implement closed management of the storage area, accessible only to trained and authorized personnel. At the same time, to prevent container deformation or damage due to overstacking, which could cause leakage risks, the stacking layers must comply with the corresponding safety regulations.

Application Recommendations

After each use, the product container opening must be immediately resealed tightly to prevent moisture absorption and oxidation. If the product solidifies or stratifies due to ambient temperature being lower than its melting point, this is a normal physical phenomenon and does not affect its intrinsic quality. Before opening and use, the package can be placed in a warm room above 35°C or a water bath (Do not use open flames for direct heating) to slowly melt and then homogenize before normal use.

Precautions

  • Personal Protection: According to the safety data sheet, this product causes skin and eye irritation (H315, H319). When handling and transferring the product, be sure to wear qualified chemical-resistant gloves, goggles, and protective clothing.
  • Emergency Response: In case of leakage, use inert absorbent materials such as dry sand or vermiculite to contain and collect. Disposal of waste must comply with local environmental regulations; do not discharge directly into water bodies or the environment.
  • Quality Confirmation: For inventory products near or beyond the recommended shelf life, it is recommended to conduct laboratory trials before use to evaluate whether key performance indicators (such as pH value, hydroxyl value, amine value) still meet application requirements.
