of the present invention can be used in a liquid injection molding process in which the composition is injected into light weight molds under low pressures such as 600 kpa cylinder pressure such compositions can be cured very rapidly in a hot mold and removed without cooling the mold the type of molding extruding or curing process used is not narrowly critical and can include those known in the art an advantage of the compositions of this inventions is the extrudability which makes it adaptable to molding processes such as liquid injection molding at low pressures the prepared compositions have a viscosity such that at least 45 grams per minute can be extruded through a 3 175 millimeter orifice under a pressure of 620 kilopascals preferably the viscosity is such that at least 50 grams per minute can be extruded the silicone elastomeric compositions can readily be prepared in conventional mixing equipment because of its fluid nature the order of mixing is not critical if the composition is to be used immediately however it is preferable to combine a c and d and thereafter add b this permits the small amount of d to become well dispersed in a and c prior to the beginning of any curing reaction suitable two package composition can be made using.
