Weld Through Sealant
CS 3204 WT20 is a fuel resistant faying surface weld through sealant for metal parts joined by resistance welding. The cured CS 3204 WT20 may be subjected to aircraft fuels, lubricants, oils, water and/or weathering.
CS 3204 WT20 is a two-part; polysulfide synthetic rubber compound with aluminum powder mixed in the base compound forming the conductive component. CS 3204 WT20 cures at room temperature to a flexible resilient rubber with excellent adhesion to aluminum, magnesium, titanium, steel, and numerous other materials.
