Octadecyl Polyoxyethylene Ether AC-1812 should be stored in a cool, dry, well-ventilated warehouse (temperature below 35°C). Under original sealed conditions, the shelf life is two years from the date of production.

Detailed Description

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 Conditions

Storage RequirementSpecific Description
Temperature ControlMaintain warehouse temperature below 35°C, avoid drastic temperature fluctuations
Environmental RequirementCool, dry, well-ventilated dedicated warehouse
Light RequirementKeep away from ignition sources, heat sources, and direct sunlight
Package SealingContainers must remain sealed; reseal immediately after opening
Isolated StorageStore strictly separately from oxidizers, acids, alkalis, flammable items, and food or feed
Shelf LifeUnder original sealed conditions meeting the above storage requirements, the shelf life is two years from the date of production

Application Recommendations

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.

Precautions

  • It is recommended to wear dust masks, chemical safety goggles, chemical-resistant gloves, and long-sleeved protective clothing during operation.
  • During transportation, prevent packaging damage and avoid mixing with strong oxidizers.
  • In case of leakage, carefully sweep up using non-sparking tools, place into dry, clean, lidded containers, and dispose of through qualified units to prevent entry into sewers or water bodies.
  • This product is not classified as flammable solid, but may melt and decompose at high temperatures, producing irritating or toxic fumes. Suitable extinguishing media: water fog, alcohol-resistant foam, dry powder, carbon dioxide.
