ABSTRACT:
A process and composition for applying and bonding an indicia which is curable at ambient temperatures to a cured elastomer substrate. The substrate is treated generally at ambient temperatures with organic oxidants selected from the group consisting of N-halosulfonamides, N-halohydantoins, N-haloamides, N-haloimides, and the various isomers of mono-, di-, and trichloroisocyanuric acid. The indicia which is generally a urethane polymer or prepolymer is blended with an amine curing agent. A polar solvent is added to the amine curing agent and the amine curable polymer or prepolymer composition and mixed with the resulting blend or mixture applied to the treated elastomer surface in the form of an indicia so that said polymer or prepolymer cures at ambient temperature and is bonded to said elastomer. The invention is particularly suitable for applying indicia to various elastomer articles such as tires, conveyor belts, hoses, floor mats, sporting goods, and the like. An advantage of the invention is that the indicia can be made utilizing liquid components, mixed and applied at the site.
