METHOD OF TREATING SUBSTRATES WITH IONIC FLUOROPOLYMERS

摘要

The present invention provides a method of treating a substrate to improve the alcohol repellency of the substrate while minimizing the effect on the hydrostatic head value of the substrate that includes contacting a substrate with a treatment solution that includes an ionic fluoropolymer, a monovalent salt, and essentially no antistatic agent or less than 0.05 weight percent by weight of an antistatic agent.
