Antistatic Agent MOA3PK-70 (fatty alcohol polyoxyethylene (3) ether phosphate potassium salt) is an anionic antistatic additive, appearing as a light yellow to yellow transparent liquid at room temperature. Although it is not classified as a flammable or explosive dangerous good (flash point > 100°C), its GHS classification includes Skin Irritation Category 2 (H315) and Serious Eye Irritation Category 2A (H319), requiring strict protection during handling. At the same time, to ensure optimal antistatic performance, the addition amount in plastic processing, processing temperature control, and compatibility with other additives must be properly managed.
In practical applications, the liquid form of this product facilitates precise metering and uniform dispersion. However, due to its anionic nature, it should be avoided to mix directly with cationic additives to prevent ionic interaction that could lead to functional failure or precipitation. The following detailed instructions are provided from three aspects: safe operation, process control, and storage.
| Protected Area | Protective Requirement |
|---|---|
| Eyes | Wear chemical safety goggles or face shield to prevent liquid splashes into eyes |
| Hands | Wear chemically resistant nitrile rubber gloves; after contact, wash thoroughly with soap and water |
| Body | Wear impermeable work clothing to avoid direct skin contact |
| Respiratory | In poorly ventilated areas, wear respiratory protective equipment with appropriate filter cartridges |
| Precaution | Specific Requirements and Recommendations |
|---|---|
| Addition Amount | For internal antistatic modification of plastics, the recommended addition amount is 0.3% to 1.5% of the resin weight (specific amount to be determined by tests based on target surface resistivity) |
| Processing Temperature | Injection molding or extrusion processing temperature should not exceed 260°C to avoid decomposition of phosphate ester groups and loss of antistatic effect |
| Dispersion Uniformity | It is recommended to pre-compound with resin into masterbatch before use, or use side feeding to ensure uniform distribution in the substrate |
| Compatibility Restrictions | As an anionic additive, avoid combining with cationic antistatic agents or quaternary ammonium salts; can be well compatible with nonionic and anionic additives |
| Application in Spinning | When used as a component in synthetic fiber spinning oils, the emulsion concentration should be controlled at 0.5% to 3%, and the pH value maintained within 6 to 8 |
| Application in Coatings and Inks | Addition amount is usually 0.2% to 1.0% of the total formula; stir thoroughly to disperse, and if necessary, pass through a grinding process to ensure compatibility with the coating system |
| Contact Route | First Aid Measures |
|---|---|
| Skin Contact | Immediately remove contaminated clothing, wash with plenty of running water and soap for at least 15 minutes; seek medical attention if irritation persists |
| Eye Contact | Immediately open eyelids, flush gently with running water or saline for at least 15 minutes, rotate eyeballs, and seek medical attention as soon as possible |
| Inhalation | Move quickly to fresh air, keep airway open; if breathing difficulty, administer oxygen; if breathing stops, immediately perform artificial respiration and seek medical help |
| Ingestion | Rinse mouth with water, do not induce vomiting; if conscious, drink a small amount of warm water to dilute; do not give anything by mouth to an unconscious person; seek immediate medical attention |
| Spill Handling | For small spills, cover with inert absorbent materials such as dry sand or vermiculite and collect; for large spills, isolate the area, transfer using an explosion-proof pump, and prevent entry into drains or water bodies |
In summary, Antistatic Agent MOA3PK-70 is a safe and effective antistatic additive under proper handling conditions. The key lies in personal protection of skin and eyes, reasonable control of processing temperature and addition amount, avoidance of mixing with cationic additives, and strict implementation of sealed storage.
