An improved reinforcing silica filler is made by first treating a reinforcing silica filler with ammonia and then treating the filler with hexamethyldisilazane. The treated filler when used in a composition containing a silanol end-stopped polydimethylsiloxane curable to a silicone rubber, provides improved shelf stability of the curable composition and also provides improved strength in the cured composition.
