Antistatic agent MOA3PK-70 is a high-performance anionic antistatic additive with fatty alcohol polyoxyethylene (3) ether phosphate potassium salt as the core component, CAS number 39322-78-6, widely used in plastic modification, synthetic fibers, and coating industries to eliminate static accumulation.

Detailed Description

Antistatic agent MOA3PK-70 (also known as alcohol ether phosphate potassium salt) is a functional chemical auxiliary produced by Haian Guoli Chemical Co., Ltd., appearing as a light yellow to yellow transparent liquid. Its core chemical composition is fatty alcohol polyoxyethylene (3) ether phosphate potassium salt, belonging to anionic surfactants. This product, with its excellent antistatic performance and broad resin compatibility, has stable applications in multiple industrial fields.

From the mechanism of action, MOA3PK-70 can form conductive channels within the material, significantly reducing surface resistance even at low addition levels, quickly dissipating static charge accumulation, thereby effectively preventing dust attraction, adhesion, and discharge phenomena caused by static electricity on products. Due to its good internal compatibility with various general-purpose resins such as PE, PP, PS, ABS, and flexible PVC, the antistatic effect is lasting and stable, not easily lost by washing or wiping, which is a significant advantage distinguishing it from common external coating antistatic agents.

In addition to the core antistatic function, MOA3PK-70 also possesses excellent emulsifying and wetting properties. It can serve as a core component in synthetic fiber spinning oil formulations, imparting good cohesion and smoothness to fibers, effectively reducing broken filaments and ends during processing. Meanwhile, this product maintains chemical stability over a wide pH range, has good tolerance to calcium and magnesium ions in hard water, and its liquid form facilitates precise metering and uniform dispersion.

Application Recommendations

Internal Antistatic Modification of Plastics: Suitable for injection molding, extrusion, or blow molding products of polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS resin, and flexible polyvinyl chloride (PVC), used as a long-term internal antistatic agent, can significantly reduce surface resistivity and persistently eliminate static accumulation. Recommended to be added through conventional compounding processes; liquid form facilitates precise metering and uniform dispersion.

Synthetic Fiber Spinning Oil Formulations: Used in spinning and post-processing oil formulations for synthetic fibers such as polyester (PET), nylon (PA), and polypropylene (PP), providing excellent antistatic, smoothing, and cohesive properties, reducing broken filaments during fiber formation and processing while improving spinnability.

Coatings and Printing Inks: As a functional additive added to coating systems, it can effectively prevent dust accumulation on the coating surface, reduce static interference during printing, and improve coating cleanliness and printing precision.

Precautions

  • This product may cause skin irritation (H315) and serious eye irritation (H319). Wear chemically resistant protective gloves (e.g., nitrile rubber gloves) and chemical safety goggles during operation.
  • Store sealed in a cool, dry, and well-ventilated warehouse, away from heat sources, sparks, and open flames. Immediately seal the container after use to prevent moisture absorption and contamination.
  • Keep away from strong oxidizers, strong acids, and strong bases. The storage area should be equipped with spill containment trays, and the floor should be impermeable.
  • Although the flash point is greater than 100°C and it is not classified as a flammable liquid, grounding facilities should still be used during operation to prevent static accumulation.
