RTV5243 – Silicon Rubber Adhesive



RTV5240 series sealants are alkoxy neutral cure, one-component, ready to use, electronic grade silicone adhesive sealants exhibiting high strength that will maintain a strong bond even when exposed to moist environments. RTV5240 series sealant are true neutral curing silicone sealants that release methyl alcohol during cure while exposed to atmospheric moisture at room temperature. Unlike most alkoxy curing silicone sealants, RTV5240 series cures very rapidly.
