Connections with irregular shapes are at risk of corrosion, especially in humid environments.
To solve the problem of protecting odd-shaped conductors, 3M scientists created mastic electrical tapes from their knowledge of adhesive technology. 3M mastic tapes are made of thick, flexible material that pads quickly and efficiently around sharp angles and small crevices. When applied, they create a smooth taping surface that reduces the risk of water damage.
Discover which 3M mastic electrical tape to use for each application.
Moisture in humid industrial environments can damage exposed metal conductors. Use 3M mastic electrical tapes to create a thick, water resistant seal. Even when punctured, the mastic will continue to protect the conductors with its self-healing properties that flow to fill in the void.
Choose these 3M mastic electrical tapes for a moisture-tight seal.
Splices with sharp corners, bolted connections on bus bars, irregular shapes and rough surfaces must be insulated with mastic tapes to prevent air pockets and punctures. 3M mastic electrical tapes are highly flexible and conform over odd-shaped components. They can be tucked into hard-to-reach spaces, resulting in a smooth, uniform wrap.

Jackets of connectors in outdoor environments are at risk of cracking due to sun exposure, leaving the wire vulnerable to rain damage. 3M mastic electrical tapes have thick, stretchy material made for weather-exposed applications. Their heat, UV and moisture-resistant attributes reinforce the security of the connection.
