Abstract

A method is disclosed comprising: adding an additive (116) to a release agent (113), the additive (113) having an extinction coefficient or a maximum extinction coefficient above a predefined threshold for electro-magnetic radiation having a predefined wavelength or a predefined wavelength range; disposing the release agent (113) comprising the additive (116) between a preformed tire (109) and a curing bladder (106) of a tire curing press (100); curing the preformed tire (106) in the tire curing press (100), thereby resulting in a cured tire (111); and performing a laser cleaning of an innerliner (123) of the cured tire (111) using a laser (126) that generates a laser beam (129) at the predefined wavelength or the predefined wavelength range. Also, a composition is disclosed comprising a release agent (113) that prevents a curing bladder (106) of a tire curing press (100) from adhering to an innerliner (123) of a cured tire (111) and an additive (116) added to the release agent (113). The additive (116) has an extinction coefficient or a maximum extinction coefficient above a predefined threshold for electro-magnetic radiation having a predefined wavelength or a predefined wavelength range. The additive (116) promotes or increases ablation of the release agent (113) compared to the same composition without the additive (116) when a laser beam (129) having the predefined wavelength or having the predefined wavelength range is applied to a surface of the innerliner (123) of the cured tire (111) comprising the release agent (113).
