Abstract

The invention relates to a composite comprising a porous substrate at least partially coated with a coating layer prepared from curing a coating composition (C), the coating composition (C) comprising at least one curable perfluoropolyether (PFPE) polymer. The invention further relates to a process for manufacturing a composite as afore-described, comprising the steps of: (a) providing a coating composition (C) comprising at least one curable perfluoropolyether (PFPE) polymer; (b) depositing said coating composition (C) on a porous substrate; and (c) crosslinking said coating composition (C) to form a porous substrate at least partially coated.
