Yes, 3M Rubber Electrical Tapes are engineered to repel moisture, making them perfect for outdoor applications. If wrapped properly, self-fusing rubber tapes can provide a watertight seal. To further protect against harsh environments, it's recommended to overwrap the rubber tape with durable vinyl electrical tape. These tapes are also built to withstand high temperatures, making them suitable for applications near motors, heat vents, or blast furnaces.
