The antistatic agent MOA3PK-70 (fatty alcohol polyoxyethylene (3) ether phosphate potassium salt) is a light yellow to yellow transparent liquid. It is an internal additive type antistatic agent that needs to be directly incorporated into the system during material processing, rather than being applied as a surface coating. Its mechanism of action is to form conductive channels within the material through hydrophilic groups in the molecule, conducting static charges from the material surface to the interior and gradually dissipating them. Therefore, the antistatic effect is durable and not easily失效 due to washing or wiping.
In plastic modification applications, MOA3PK-70 is usually added together with the resin base material during the mixing or extrusion stage. Its liquid form allows precise injection into a twin-screw extruder or internal mixer via a metering pump, or it can be pre-mixed with a small amount of resin powder to form masterbatch before use. The processing temperature should be controlled within a safe range below the product's flash point (>100°C). In synthetic fiber spinning oil applications, MOA3PK-70 serves as a core component of the oil formulation, compounded with other smoothing agents and emulsifiers in proportion, then applied to the fiber surface via oiling rollers or spray systems.
In coatings and inks applications, MOA3PK-70 can be added directly during the paint mixing stage and thoroughly stirred to disperse. Due to its excellent emulsifying and wetting capabilities, no additional dispersing aids are required for uniform distribution in the system. It is recommended to conduct small-scale tests before use to determine the optimal dosage and process conditions suitable for the specific formulation.

Internal antistatic modification of plastics (PE\/PP\/PS\/ABS\/Soft PVC): Use internal mixing method. During the mixing, extrusion or injection molding stage, add liquid MOA3PK-70 proportionally into the resin melt. It can be directly injected into processing equipment via a metering pump, or pre-mixed with carrier resin to form a high-concentration masterbatch and then diluted before use. Suitable for conventional molding processes such as injection molding, extrusion, and blow molding. The industry reference dosage is typically 0.5% to 3% of the resin weight. The specific dosage should be determined experimentally based on the target surface resistivity and resin type. (Note: There is no officially recommended dosage in the database; the above is a general industry reference range.)
Synthetic fiber spinning oil (polyester\/nylon\/polypropylene): Use MOA3PK-70 as the core antistatic component in the oil formulation, compounded with other smoothing agents, emulsifiers, and bundling agents in a mixing tank according to the formulation ratio. The prepared oil is applied to the fiber surface via oiling rollers or metering spray systems during spinning and post-processing stages, imparting good antistatic properties, cohesion, and smoothness to the fiber.
Coatings and printing inks: During the paint or ink mixing stage, add MOA3PK-70 directly into the system and disperse it at medium to high speed (recommended 500~1000 rpm) for 10~15 minutes to ensure uniform distribution. Particularly suitable for coating systems that need to prevent surface dust attraction and reduce static interference during printing.
