An adhesive composition includes a coupling agent composed of a compound having a first functional group that reacts with an inorganic material and a second functional group that reacts with an organic material, and a crosslinking agent capable of crosslinking with a crosslinking site of a fluorine-based elastomer. A seal structure body includes a metallic support, fluorine-based elastomer and adhesive composition that causes fluorine-based elastomer to adhere to metallic support. A method for manufacturing seal structure body includes the steps of providing metallic support and fluorine-based elastomer, and causing fluorine-based elastomer to adhere to metallic support by using adhesive composition. Accordingly, an adhesive composition with high adhesion strength as well as a seal structure body and a method for manufacturing the same are provided at low cost.

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: ##STR00001## wherein x is 1 or 2, y is 0 or 1. The moieties R.sup.1 and R.sup.2 can be the same or different. The moieties R.sup.1 and R.sup.2 can be selected from the group consisting of methyl, ethyl, n-propyl, i-propyl, and a functionalized alkyl group R(CH.sub.2).sub.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.

A tube used or medical or other purposes is concentrically bonded to an inner lining tube by sequentially inserting a core within the inner lining tube, creating an adhesive layer on the outer surface of the inner lining tube, inserting the inner lining tube and core into the lumen of the outer tube, and then activating the adhesive to bond the inner tune to the outer tube before removing the core.
