Abstract: The disclosed technology generally relates to methods for forming coatings on metal substrates to promote adhesion between the metal substrate and an elastomer layer. In one aspect, a method of forming the coated article includes providing a meal substrate, preparing a sol mixture for forming a ceramic coating, depositing the sol mixture onto a surface of the metal substrate, and then heating the metal substrate and sol mixture to form the ceramic coating. Preparing the sol mixture comprises preparing a first transition metal sol, a second transition metal sol, a metalloid sol, and then mixing the first transition metal sol, the second transition metal sol, and the metalloid sol together.

Abstract: The present invention relates to a rubber composition which can be used to form a sealing strip, a process for the preparation of this composition and such a sealing strip. The composition according to the invention, which can be used to form, in the crosslinked state, a sealing strip exhibiting a non-tacky surface and a reduced compression set, is based on at least one elastomer and comprises a crosslinking system comprising at least one organic peroxide. According to the invention, this composition comprises: (pce: parts by weight per 100 parts of elastomer(s)) at least one first organic salt of at least one transition metal chosen from the group consisting of manganese, iron, cerium and vanandium, according to an amount equal to or greater than 2 pce, and at least one second organic salt of at least one other metal chosen from the group consisting of zinc, zirconium, lithium, calcium and barium, according to an amount equal to or greater than 2 pce.
