Our R&D team uses Olympus BX63 microscopes to monitor pigment dispersion (5μm precision), adding color paste in 0.01g increments for ΔE<1 precise coloring (imperceptible to the naked eye). With a database of 500+ mature base formulas, we quickly respond to custom requests—whether low-VOC eco-formulas, fast-curing formulas, or special effects (cat eye, holographic)—completing R&D and sampling in 7 days. The lab also has small-scale constant-temperature dispersion testers and micro vacuum defoamers, ensuring 1:1 parameter matching between lab trials and mass production for smooth formula scaling.
