A coating, in particular a coating for a back side of a brake pad opposite a braking side, includes a pair of bonding layers and a composite layer. Each of the bonding layers includes an epoxy material. The composite layer is disposed between the pair of bonding layers, and includes a mixture of a rubber material and particles of a secondary material. A method for forming the coating includes coating a layer of epoxy onto the surface to be coated to form a first bonding layer, coating the mixture of the rubber material and particles of a secondary material onto the first bonding layer to form a composite layer, coating a layer of epoxy to the composite layer to form a second bonding layer, and then curing the coating via a curing process.

A hydrogenated NBR composition comprising 30 to 200 parts by weight of titanium oxide and 1 to 8 parts by weight of magnesium oxide, based on 100 parts by weight of hydrogenated NBR. By forming a crosslinked rubber layer of the rubber composition on a metal plate, a gasket material with excellent blister resistance, whose roll kneadability is improved without reducing the rubber strength of hydrogenated NBR, is provided. Moreover, the rubber composition is effective as a rubber raw material for use in soft metal or a high hardness hydrogenated NBR material for which kneading processing is difficult.

Shelf-stable low temperature cure coating compositions that include a hydroxy-functional resin, a crosslinking agent, and a catalyst that does not catalyze the crosslinking reaction between hydroxy-functional resin and the crosslinking agent contained therein, but instead between a hydroxy-functional resin and a crosslinking agent contained in a different low temperature cure coating composition. In addition, low temperature cure composite coatings that include: a waterborne basecoat containing a first hydroxy-functional resin, a first crosslinking agent, a first catalyst, and an organic solvent; and a solventborne topcoat containing a second hydroxy-functional resin, a second crosslinking agent, a second catalyst, and water, where the first catalyst migrates into the topcoat from the basecoat and catalyzes the reaction between the second hydroxy-functional resin and crosslinking agent, and the second catalyst migrates into the basecoat from the topcoat and catalyzes the reaction between the first hydroxy-functional resin and crosslinking agent.
