Abstract
A curable, reinforced polydiorganosiloxane microemulsion is prepared by adding from 5 to 30 parts by weight of colloidal silica per 100 parts by weight of polydiorganosiloxane in the microemulsion and from 1 to 5 parts by weight of dialkyltindicarboxylate catalyst per 100 parts by weight of the microemulsion to polydiorganosiloxane microemulsion. The curable, reinforced polydiorganosiloxane emulsion can be cast into coherent, elastomeric films of less than 0.4 micrometer thickness.
