Abstract:

An improved process for producing a silicone composition useful as a green tire lubricant with improved lubricity properties comprising mixing initially the diorganopolysiloxane with a mica filler to form a homogeneous mixture and then subsequently adding to this mixture the other necessary ingredients such as a polyol, a mineral clay, an emulsifying agent and finally adding water and mixing the mixture to produce a dispersion. There is a second improved process in accordance with the present invention in which the viscosity of the final green tire lubricant mixture irrespective of how it is prepared is decreased by the addition of buffering agents.
