Abstract
Abstract A preformulated inside green tire lubricant and bag release composition comprising a silicone fluid; an alkylene oxide polyol; a particulate solid for providing air bleed channels between the expanding pressure core and the green tire; water; and sufficient suspending and emulsifying agents to provide a stabilized, non-settling suspension. An example of the lubricant is as follows: Lubricant A. water base B. silicone fluid C. glycerol adduct of propylene oxide D. mica E. magnesium silicate F. amine salt of alkylarylsulfonic acid.
