  • Patent number: 10563696
    Abstract: A slide bearing can include a metal support, a primer layer, an adhesive layer applied directly thereto, and a sliding layer applied to the adhesive layer. The primer layer can include an oligomeric condensate of at least one silanol selected from the group having the formula: wherein x is 1 or 2, y is 0 or 1. The moieties R1 and R2 can be the same or different. The moieties R1 and R2 can be selected from the group consisting of methyl, ethyl, n-propyl, i-propyl, and a functionalized alkyl group R?—(CH2)z—, wherein z is at least 1. Slide bearings comprising a primer system based on silanol oligomeric condensates show improved peel strength than their analogous slide bearings lacking the primer system.

  • Patent number: 9803690
    Abstract: Slide bearings and methods of producing slide bearings are disclosed. The slide bearing has a metal support and a sliding layer. No other layer is in contact with the sliding layer. The sliding layer is applied directly to the metal support. The sliding layer comprises a mixture of at least two polymers P1 and P2, wherein P1 is a fluoropolymer. P2 is a non-fluorinated thermoplastic polymer.

  • Patent number: 9297416
    Abstract: Slide bearings and methods of producing slide bearings are disclosed. The slide bearing has a metal support, an adhesive layer and a sliding layer. The adhesive layer is applied directly to the metal support. The adhesive layer comprises a blend of at least two fluoropolymers P1 and P2, wherein P1 is selected from perfluoroalkoxyethylene (PFA) or tetrafluoroethylene-hexafluoropropylene (FEP). P2 is different from P1 and can be a fluoropolymer.
