The main component of Rapid Penetrant T-70E (Wetting Agent OT) is dioctyl sulfosuccinate sodium salt (70% solution), which belongs to the anionic surfactant category. Under appropriate storage conditions, this product has good chemical stability, but improper storage environment may cause product stratification, deterioration, or performance degradation. To maintain the product's penetrating and wetting performance to the greatest extent, the following storage specifications must be strictly followed.
Regarding the shelf life: According to the product database of Guoli Chemical, this product currently has no official shelf life data. Based on industry practices, sulfosuccinate surfactants (70% solution) under original sealed and recommended storage conditions typically have a shelf life of 12 months from the production date. After the shelf life expires, it is recommended to contact the technical team for performance retesting; confirmation of key indicators such as penetrating power, pH value, and active matter content is required before continued use. For specific batch validity, please refer to the product packaging label or the Certificate of Analysis (COA).
During storage, if obvious stratification, increased turbidity, unusual odor, or color darkening are observed, the product should be stopped even if the shelf life has not expired, and the Guoli Chemical technical team should be contacted for quality assessment.
| Storage Element | Specific Requirement |
|---|---|
| Ambient Temperature | Recommended to be kept between 5°C and 35°C; Freezing is strictly prohibited; Avoid long-term storage in high temperatures (>40°C) |
| Storage Environment | Cool, dry, well-ventilated dedicated warehouse, away from heat sources, sparks, and open flames; Protect from direct sunlight |
| Container Sealing | Keep sealed when not in use; After opening, re-seal carefully and keep upright to prevent water evaporation and external contamination |
| Container Material | Packaging containers must be sturdy and intact, and the material must be compatible with the product (stainless steel, polyethylene, or plastic-lined containers are recommended) |
| Prohibited Isolation | Keep away from strong oxidizers, strong acids, strong bases, and other incompatible materials; Do not mix or transport with food, beverages, or animal feed |
| Floor Protection | Storage area floor should be laid with anti-seepage, corrosion-resistant materials, and equipped with secondary containment such as dikes or collection trenches. |
To ensure stable product performance, it is recommended to follow the First-In-First-Out (FIFO) principle, prioritizing the use of earlier batches. After each use, immediately seal the container to minimize prolonged exposure of the product to air, thereby delaying potential oxidation or moisture absorption. In low-temperature winter environments, the product viscosity may increase; before use, the container can be placed in a room temperature environment to naturally warm up (do not heat directly). After the fluidity is restored, stir evenly before normal use.
