VarnishFill VF-700 Series
Clarity in Every Can
Core Innovation: Bubble-Free Precision for Optical-Grade Finishes
Shanghai Guangzhi VF-700 delivers ±0.3% volumetric accuracy for polyurethane/alkyd/nitrocellulose varnishes (100-50,000 cP) via vacuum degassing, Peltier temperature control, and self-purging nozzles. Achieving 50 cans/hour with <0.1% haze formation, it solves clarity degradation, viscosity drift, and cross-contamination in furniture, automotive, and precision coating industries.
