Title:
PROCESS FOR IMPARTING GREASE, OIL AND WATER REPELLENCE TO SUBSTRATES
Document Type and Number:
WIPO Patent Application WO/2010/000715
Kind Code:
A8
Abstract:
The invention pertains to a process for imparting grease, oil and water repellence to a substrate, said process comprising applying by means of a printing process on at least a portion of the surface of said substrate a composition comprising at least one (per)fluoropolyether derivative. The Applicant has found that by means of the process of the invention it is possible to confer suitable grease, oil and water repellence properties to substrates via selective treatment/coating, by significantly reducing total amount of fluoro-containing additive required for the target properties.
