Fluorosurfactants are anionic, cationic, or non-ionic surface-active materials having perfluorinated alkyl groups in their molecules. They strongly reduce surface tension and diminish the surface-tension gra­dient at the coating surface. They are more often used as anti-crater agents. The dosage of this type of flow additives should be just enough to achieve the desired effects, because they have side effects such as foam stabilization and poor intercoat adhesion when overdosed.
