Antistatic agent MOA3PK-70 (Fatty alcohol polyoxyethylene (3) ether phosphate potassium salt, CAS No.: 39322-78-6) is a high-performance anionic antistatic additive produced by Guoli Chemical. It appears as a light yellow to yellow transparent liquid. Its core advantage lies in its highly efficient antistatic performance—it significantly reduces the surface resistance of materials at low addition levels, quickly dissipates static charge accumulation, and effectively prevents dust attraction, adhesion, and discharge phenomena caused by static electricity in finished products.
This product features broad-spectrum resin compatibility, exhibiting good compatibility with various general-purpose resins such as polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS resin, and flexible polyvinyl chloride (PVC). Its antistatic effect is long-lasting and stable, and it does not easily lose efficacy after washing or wiping. Additionally, its excellent emulsification and wetting capabilities make it perform outstandingly in synthetic fiber spinning oils, providing fibers with good cohesion and smoothness, significantly reducing issues such as fuzz and broken ends during processing.
In terms of chemical stability, MOA3PK-70 remains stable over a wide pH range and exhibits good tolerance to calcium and magnesium ions in hard water. Its liquid form facilitates precise metering and uniform dispersion, making it suitable for conventional mixing, injection molding, coating, and oiling processes, with excellent process operability.

Internal Antistatic Modification for Plastics: Suitable for injection molding, extrusion, or blow molding products made of PE, PP, PS, ABS, and flexible PVC. It is recommended to add it during the mixing stage, utilizing its liquid form to achieve uniform dispersion, providing long-term stable internal antistatic protection for the finished products.
Synthetic Fiber Spinning Oils: As a core component of spinning and post-processing oils for synthetic fibers such as polyester (PET), polyamide (PA), and polypropylene (PP), it imparts excellent antistatic, smoothing, and cohesive properties to the fibers, enhancing spinnability and reducing broken filament rates.
Coatings and Printing Inks: When added as a functional additive to coating systems, it effectively prevents dust accumulation on the coating surface, reduces static interference during the printing process, and improves the surface quality and printing accuracy of the products.
During operation, wear chemically resistant protective gloves (e.g., nitrile rubber gloves) and chemical safety goggles to avoid direct skin and eye contact. In case of skin contact, immediately rinse with plenty of running water and soap for at least 15 minutes. If splashed into eyes, hold eyelids open and rinse with running water or saline solution for at least 15 minutes, and seek medical attention as soon as possible. The product should be sealed and stored in a cool, dry, and well-ventilated warehouse, away from strong oxidizers, strong acids, and strong bases. Immediately seal the container after use to prevent moisture absorption.
