Oil repellency grant ester oligomer and water repellency including the perfluoroalkyl part

摘要

Fluorochemical ester composition comprising an oligomeric or one or more compounds having a fluorine-containing end group of one is described, at least the long chain fluorine-containing repeating unit of at least 1. The compositions are useful as (10 coatings) 10 coating. This fluorochemical composition to impart oil and water repellency to a substrate. In another embodiment, the article and the substrate, the present invention relates to a process for imparting water repellency properties and oil repellency.
