Abstract (en)

[origin: WO2009080003A1] The invention relates to a contact or transfer roller for printing machines, particularly offset printing machines, wherein the roller has a core that is at least substantially rigid and a permanently attached coating made of a polymer material that is applied onto the core, wherein the coating, optionally by means of an bonding agent layer, is applied directly onto the core or onto an energy-elastic intermediate layer having a hardness of = 10 Shore D. According to the invention, the coating comprises at least substantially a fluorinated polymer and has a hardness of = 15 Shore D and/or a scratch hardness according to ISO 15184 of 6B or harder. The polymer material can be a duroplast material, a fluorinated polyurethane resin, polyester resin, epoxy resin, acrylate resin and/or polyether resin, a highly cross-linked non-elastic fluoropolymer, a fluorothermoplast, a polymer non-elastic fluorosilicone or a fluoropolymer paint.
