ABSTRACT:
A wear indicator for a latex product having an underlying latex structure comprises an outer layer positioned over the latex structure. The outer layer comprises latex having a particulate filler for establishing pores in the layer and a soluble colorant that leaches out of the pores. The leaching of colorant is simulative of wear of the latex product since leaching of the colorant occurs through degrading environmental exposure.
