ADESIVO PER TORTIGLIE PER PNEUMATICI

摘要

Vulcanizable rubber compositions providing excellent bonding of textile or metal reinforcing fibers thereto comprise a rubber, a filler material an N-(methylated or alkoxy methylolated) melamine and a bisphenol. Best results are achieved when a high surface area activated silica is also incorporated. The melamine compound and the bisphenol may be added separately during the making up of the composition, or the bisphenol may be dissolved in the melamine compound prior to mixing with the rubber.
