This static dissipative agent is a quaternary‑ammonium‑based cationic surfactant developed for electronic packaging and industrial coating applications. Compared with conventional non‑ionic migratory antistatic additives that heavily rely on ambient moisture, this cationic surfactant maintains acceptable static‑dissipating capability under low‑humidity environments. After incorporation into coating systems or compounded into polymer substrates, it forms a continuous conductive surface layer to d

Product Detail

Product DetailsThis cationic quaternary ammonium surfactant features positively charged hydrophilic quaternary ammonium head groups and long hydrophobic alkyl hydrocarbon tails. It can be applied in two processing modes: surface treatment for electronic packaging substrates, or direct incorporation as an internal additive into liquid industrial coating formulations.

When used within industrial coating systems, the active surfactant gradually migrates toward the coating‑air interface during curing. A uniform conductive surface layer is established on the dried coating film. The ionic structure enables static dissipation even when relative humidity drops, overcoming the main drawback of non‑ionic antistatic agents which lose efficacy in dry surroundings. For electronic packaging materials, this function minimizes electrostatic discharge events that could destroy microchips and delicate electronic assemblies during transportation, storage and handling.

Strict formulation restrictions should be observed. Being a cationic surfactant, this product cannot be mixed with anionic surfactants or anionic binders. Direct blending will trigger precipitation, flocculation, loss of static‑dissipating function and coating defects such as fish‑eyes and specks. Compatibility screening with resin, pigments and other auxiliaries is mandatory for every new coating formula.

Although it shows improved low‑humidity performance, the antistatic property is not completely humidity‑independent. Further performance degradation will still occur under extremely dry conditions. Excessive dosage will lead to surface blooming, sticky coating surfaces, reduced water resistance and deterioration of scratch resistance of the finished coating layer.

For coating applications, the typical recommended dosage ranges from 0.5 wt%‑1.7 wt% of total coating formulation. For surface‑treatment of electronic packaging substrates, working solution concentration should be adjusted according to targeted surface resistivity requirements. Pre‑production laboratory testing shall evaluate formulation compatibility, curing behaviour, surface resistivity, blooming tendency, water resistance and long‑term ageing performance.

Store the static dissipative agent in tightly sealed containers inside cool, dry and ventilated warehouse. Prevent direct sunlight and overheating. Reseal containers immediately after use to avoid moisture contamination and maintain consistent product performance.
