Zero Contamination ∙ ±0.1% Accuracy ∙ Reactive Chemistry Safe
For Amines, Isocyanates, Peroxides & Epoxy Hardeners
Shanghai Guangzhi Automation’s GZ-CureFill Series redefines safety and precision in filling aggressive curing agents. Featuring ATEX Zone 1 certification, moisture-controlled inert gas blanketing (<10 ppm H₂O), and Hastelloy® wetted paths, this system eliminates cross-contamination risks, prevents premature curing, and achieves unmatched ±0.1% gravimetric accuracy – critical for aerospace, composites, and adhesive manufacturing.
✅ Absolute Moisture Control
N₂/Ar gas blanketing with dew point monitoring (-70°C) prevents hydrolysis of isocyanates/peroxides.
✅ Reactive Material Compatibility
Hastelloy C-276/PFA fluid paths resist amines, acids, and free radicals.
✅ Leak-Free Sealing
Triple-seal diaphragm pumps + FFKM Kalrez® gaskets (pH 0–14 resistance).
✅ Explosion Proof
ATEX Ex db IIC T6 (Zone 1) for solvents/peroxide carriers.
✅ Quick-Change Isolation
Dedicated fill heads per agent type – switch in <5 mins.
