The backing is engineered for easy manual tearing in both directions, allowing Rapid single-person application without tools.

The synthetic rubber adhesive provides high initial tack designed to adhere to a variety of common industrial substrates including metal and many plastics.

The polyethylene backing is waterproof and maintains conformity under damp conditions, making it appropriate for environments where brief wetting may occur.

At 0.26mm thickness the tape lays flat with minimal bulk, permitting use in confined assemblies where clearance is limited.
