Abstract: A roll for a press section of a machine for making and/or finishing a fibrous web, such as a paper, board, or tissue machine, includes a roll body or roll shell and, disposed on the roll body or roll shell, a roll covering which has at least one functional layer which is suitable for entering into contact with the fibrous web or with a paper machine fabric. The functional layer is formed of a polymer which is a mixture of at least one prepolymer, a curing agent, a crosslinking agent, and an additive. The additive is selected from the following: perfluoropolyethers, bifunctional perfluoropolyether, or mixtures thereof.
