Antistatic agent MOA3PK-70 (fatty alcohol polyoxyethylene (3) ether phosphate potassium salt, CAS No.: 39322-78-6) is a stable anionic antistatic additive. However, in practical applications, various technical challenges may still arise due to factors such as process parameters, resin systems, storage conditions, or improper operation. Common problem scenarios include: precipitation or uneven dispersion during processing, unsatisfactory or non-persistent antistatic effects, poor cohesion or high breakage rate when used in spinning oil, and turbidity or delamination of the product after storage. For these situations, we recommend systematically investigating the root cause of the problem, such as checking whether the addition amount matches the resin, whether the mixing or stirring is uniform, whether the processing temperature exceeds the product's tolerance limit, and whether the container was not sealed promptly after use, leading to moisture absorption and deterioration.
To solve the problem efficiently, we suggest preparing the following information before contacting technical support, so that technical engineers can quickly diagnose: (1) Batch number of the purchased product (can be obtained from the label on the bucket), (2) Specific application field and processing technology (for example: PP injection molding, PE blow molding, polyester spinning oil, coating scraping, etc.), (3) Addition ratio of MOA3PK-70 in the formula, (4) Specific problem phenomenon and frequency of occurrence, (5) Relevant processing parameters (such as temperature, residence time, etc.). Detailed and accurate field information is the key to remote technical diagnosis.
As the manufacturer, Haian Guoli Chemical Co., Ltd. bears the responsibility of technical support for the entire lifecycle of the product, from R&D, pilot scale to large-scale application. Its technical team can help you analyze the cause of the problem, optimize the usage formula, conduct small-scale tests for verification, and even provide on-site technical guidance when necessary. As a mature industrial additive, most application problems of MOA3PK-70 can be effectively resolved through technical communication.
The following are the key physicochemical properties of MOA3PK-70 for reference. If the problem is related to the product state, you can check against them:
| Parameter Name | Typical Value / Range | Potential Problem Indicator |
|---|---|---|
| Appearance | Light yellow to yellow transparent liquid | If obvious turbidity, delamination, gel or precipitation occurs, the product may have deteriorated, been frozen or overheated |
| Active Content | ≥70% | If the content is abnormal, it may affect the accuracy of addition amount calculation |
| pH Value (1% Aqueous Solution) | 5.0~7.0 | Significant deviation of pH value may affect compatibility with some acid-base sensitive systems |
| Moisture Content | ≤30% | Excessive moisture may cause foaming during processing or affect the transparency of plastics |
| Monophosphate Content | ≥60% | The ratio of monoester/diester directly affects emulsification, wetting and antistatic efficiency |
| Free Phosphoric Acid (as P₂O₅) | ≤1.0% | Excessive free phosphoric acid may cause equipment corrosion or affect system stability |
| Flash Point (Closed Cup) | >100℃ | Used to evaluate safety during high-temperature processing |
