Development of alternate silicone potting compounds. Volume 8. Development of an alternate substitute for Dow Corning aerospace sealant DC93-122 based on Sylgard 184 and dielectric gel Q3-6527

A second substitute was formulated for Dow Corning DC93-122 silicone potting compound because the first substitute proved so strong and hard. The second substitute was made weaker by substituting Sylgard 184 for Sylgard 186 and by adding dielectric gel Q3-6527. Accelerator QCF3-6559, DC1107 fluid, and Cabosil Grade MS75 silicon dioxide were still required. To reduce the porosity of the potting, the amount of DC1107 fluid in the formulation was minimized, which required adding a relatively large amount of accelerator (as was done in the first substitute). Dielectric gel Q3-6527 used alone required considerably less silicon dioxide to achieve a non-flow state than did Sylgard 184 or any of its blends with Q3-6527.
