AMBIENT TEMPERATURE REPAIR OF ELASTOMERIC ARTICLES HAVING A HOLLOW OR DEFORMITY THEREIN

摘要

The repair of a reinforced elastomer article (10) having a hollow (12) therein relates to utilizing an amine curable polymer or prepolymer and a cured elastomer patch. The hollow (12) in the elastomer as well as the areas juxtaposition to the patch (20) is coated with a treating agent (30). The amine curable polymer or prepolymer (40) which may have rubber particles therein is then applied to the hollow as well as to the area between the patch and the elastomer and cured at ambient temperature. Alternatively, gum rubber is directly applied to the hollow and also to the treated patch area. One area of use is in the repair of tires.
