We degas gel polish materials for 20 minutes at -0.1MPa, using a spiral conveyor to spread the material into a thin film, eliminating 99.7% of micro-bubbles. Laser bubble detectors monitor fluid density in real time, ensuring deviation ≤0.05g/cm³, which prevents pinholes, shrinkage, or uneven surfaces after application. This process delivers a baby-smooth base for your premium custom gel polish, perfect for gradients, marbling, or mirror finishes. We also conduct batch sampling to ensure consistent quality for your custom products.
