This solid modified quaternary ammonium antistatic agent is specially designed for thermoset powder‑coating formulations. It is incorporated during extrusion compounding to evenly distribute inside the powder coating matrix. By moderately adjusting particle‑level conductivity of powder granules, the additive optimizes electrostatic charging behaviour at the spray gun. It effectively reduces common coating defects such as back‑ionization, pinholes and orange‑skin, improves powder transfer efficie

Product Detail

Product DetailsThis modified solid quaternary ammonium salt is a non‑volatile granular additive suitable for the hot‑melt extrusion manufacturing workflow of powder coatings. It is dosed together with base resin, curing agent, pigments and fillers at the premixing stage, then homogenized through twin‑screw extrusion, cooling, crushing and fine milling into finished coating powder.

After incorporation, the functional ingredient is dispersed within each powder particle. It modifies the surface conductivity of powder granules, allowing powder particles to acquire stable electrostatic charge when passing through the high‑voltage electrostatic field of the spraying gun. Sufficient and consistent electrostatic charge strengthens the attractive force between powder particles and the grounded metal workpiece. Higher transfer efficiency reduces the quantity of over‑sprayed powder, cuts raw‑material consumption and lessens the burden on powder recovery systems. It suppresses back‑ionization defects that frequently appear on thick coating layers, minimizing pinholes, craters and orange‑skin imperfections on cured coating surfaces.

Formulation compatibility testing is essential for different resin systems. Over‑addition of this quaternary ammonium antistatic agent may negatively influence storage anti‑caking performance of finished powder coating, accelerate premature curing during extrusion, reduce coating film insulation and cause discoloration after oven baking. It does not replace carbon‑based conductive agents for highly conductive powder coating requirements; this product targets moderate conductivity adjustment for improving spraying deposition.

The typical recommended dosage ranges from 0.2 wt%‑1.6 wt% based on the total powder coating formulation weight. Pre‑production laboratory evaluation must cover premixing stability, extrusion thermal behaviour, powder storage caking resistance, electrostatic spraying performance, baking curing profile, cured‑film gloss, impact resistance and anti‑yellowing property before formal mass production.

Store the solid additive in sealed moisture‑proof bags within cool, dry and ventilated warehouse. Keep away from high‑temperature environments to prevent lump formation. Avoid direct sunlight. Reseal packaging immediately after opening to block moisture absorption and preserve consistent processing performance.
