Abstract

The present invention is based on the discovery that a cured organic or organosiloxane gel will enter and flow through a conduit to a dispensing location as a coherent, homogeneous portion of material when 1) one end of the conduit is immersed in the gel, 2) a sufficient pressure differential is applied between the surface of the gel and the interior of the conduit to cause the gel to enter and at least partially fill a portion of the conduit, and 3) sufficient pressure is then applied within the conduit to cause the gel to flow in the conduit to at least one dispensing location where the gel is withdrawn from the conduit as an integral, homogeneous stream of material.
