A fluorocarbon leveling agent (fluoride-containing surfactant) for coating and ink has the surface tension of the leveling agent of 21-24 dynes, the number-average molecular weight of 1500-4500, the weight-average molecular weight of 3000-15000, and the polydispersity of 1.5-2.8. The present invention can reduce the surface tension of the coating system and has strong anti-shrinkage capability and excellent long wave leveling. |
