Urea-aldehyde condensates and melamine derivatives comprising fluorochemical oligomers

摘要

Fluorochemical compositions comprising fluorinated compounds, wherein the fluorinated compound comprises fluorochemical oligomeric portion bonded through -O-, -S-, -NH-, or CO2- to a moiety comprising a group derived from an amino resin. Also disclosed are fluorochemical compositions in the form of fluorochemical liquid dispersions and methods for preparing substrates treated with such compositions. Substrates so treated exhibit particularly durable and abrasion-resistant oil and water repellent properties.
