​The most important construction step in tire production is the curing of the assembled tire. Tire curing is performed in a heated press, usually equipped with metallic molds to shape the outside of the tire during vulcanization. Inflatable rubber bladders shape the inside of the tire and press it against the metallic mold.

Releasing the cured tire from the inflatable mold (the bladder) is a vital step – without a release agent, tire rubber and bladder rubber would stick together after curing. Modern reactive single releases are able to form a thin release agent layer covering the rubber surface. Selected silicones, contained in these agents allow easy wetting and spreading over the rubber surface.
