Post-Cure Studies on Solid Silicone Elastomer: DC745U

DC745U is a silicone elastomer originally manufactured by Dow Corning under the name of Silastic® DC745U at their manufacturing facility in Kendaville, Indiana. Currently DC745U is available through Xiameter® or Dow Corning’s distributor R. D. Abbott Company. This silicone elastomer is used in numerous parts of weapon systems, including outer pressure pads, aft cap support in W80 and pressure pad in the B61. DC745U is a proprietary formulation and limited information about its composition and properties is provided to the customer. Thus, Los Alamos National Laboratory and Lawrence Livermore National Laboratory have performed a variety of characterization experiments on this material.
