Press cover for a shoe press or transport belt with improved hydrophobicity

A press cover for a press roll or a transport belt, the press cover or the transport belt comprising:

• at least one polyurethane-containing layer, the polyurethane being obtained by a reaction, in one or more steps, of
• i) a polyol component;
• ii) an isocyanate component;
• and
• iii) a component containing at least one crosslinker;
• wherein said polyol component comprises at least 90 wt % of one or more mutually different structural units according to the following general formula (I):
• —O—R1—X—R2—O— (I);
• wherein all R1 and R2 in the one or more different structural units according to the general formula (I) independently of one another are identical or different and are selected from linear C1-C20 alkylene groups, and all of groups X in the one or more different structural units independently of one another are identical or different and are selected from the group consisting of bond, O, C(O)—O, and O—C(O)—O;
• and
• at least 70 wt % of the structural units according to the general formula (I) meet the following criteria:
• a) at least 80% of the groups X are O—C(O)—O and a remainder of the groups X are selected from O and C(O)—O;
• and
• b) an average chain length of all the groups R1 and R2 is 8 or more than 8 carbon atoms;
• and
• c) at least 50% of the groups R1 and R2 are independently of one another each a linear C8-C12 alkylene group.
