3M™ Electrical Moisture Sealant Pads EMS II are self fusing, rubber based insulating compounds laminated to a flexible, all weather grade vinyl (PVC) backing. The pre cut pads are designed to electrically insulate and moisture seal electrical junctions for automotive, trailer, truck, heavy equipment, marine or other outdoor wiring connections.
3M™ EMS II pads have excellent resistance to abrasion, moisture, ozone, alkalies, acids, copper corrosion and varying weathering conditions. They encapsulate and seal under 600V connections and are resistant to saltwater and corrosive chemicals. These pads also resist vapors and splashes from automotive fluids. With their improved, 3 sided construction, mastic exposure is eliminated.
