Abstract:
A polyurea adhesive composition that is obtainable by reaction of reaction components that include a polyisocyanate comprising isocyanurate rings, the polyisocyanate having a functionality equal to or greater than 3, a polyamine having an average molecular weight greater than about 500 dalton and a carboxylic acid. Additionally, the reaction components may comprise an aromatic diamine chain extender. The molar ratio of the isocyanate groups to whole amine and carboxylic acid functions of the reaction components is between 1.5 and 3.5. Further provided is an article comprising a component bonded to the article with the polyurea adhesive described above. The bonded faces between the component and the article may be of cross-linked rubber composition. The article may be, for example, a tire, a tread band and/or a patch applied to the tire.
