One process for retreading tyres involves coating the buffed casing with a solution of natural rubber compound (dough), covering it with a thin layer of solid adhesive, and then applying the precured tread, also coated with dough. Reclaimed material from waste latex products has been used to prepare the adhesive. It was also shown that the addition of an ultra-accelerator to the dough just prior to its application can reduce the bonding time, and hence reduce heat aging of the tread. In the adhesive strip, a small fraction of the insoluble suphur can be replaced with soluble suphur, without significant reduction in bond strength.
