3M Scotchcast Connector Sealing Pack
Item #3570
Scotchcast™ connector sealing pack. Insulates and provides protection for electrical spring connectors against dust, soil, water, and other environmental elements. Each sealing pack contains a specific amount of the two-part 3M™ Scotchcast™ Epoxy Resin 3570G-N in a unique closed mixing pouch. The resin generates its own heat to cure and its compatibility with spring connectors makes this sealing pack a convenient insulating and encapsulating resin for electrical spring connections. (Veeder Root P/N 514100-304.)
