More stable printing
Better CP vs. IPA
IPA: CP 2.22; Urabukin-chan: CP 3.34. Lower variation has helped stabilize print from the first board after production restarts.

Why it wipes well without leaving residue
Surfactant-free proprietary design
Wetting and drying are balanced carefully. High wetting boosts wipe-off, the return wipe finishes the job, and the formula resists leaving impurities behind.
