Select waterproof tesa double-sided tape

The property must be documented for the specific version. For tesa ACXplus 07805, the product information states high moisture resistance and describes a closed-cell acrylic foam core that seals against water. tesa 61053 also describes a core that seals against water. This does not establish that every adhesive joint is watertight: the substrate, edges, bonding area and exposure all need to be assessed as part of the complete bond.

State the type and duration of exposure, such as intermittent moisture or direct water contact, and where the joint is located. Both surfaces, their preparation, the bonding area and later loads also matter for technical selection. With those details, the resistance of a particular tesa tape and the construction of the adhesive joint can be assessed for your application.

tesa 61053 is a black acrylic foam tape for display and touch-panel mounting; its product information mentions a closed-cell core and use on components designed to resist water. tesa ACXplus 07805 is a deep-black acrylic foam tape for exterior attachments and can accommodate different expansion of the bonded parts. Choose according to surfaces, geometry, exposure and the relevant product information, rather than their shared moisture-related attribute alone.

A cut or die-cut part defines shape and bonding area; it does not create an additional material property. Krückemeyer GmbH can cut suitable tapes for processing and supply them as die-cut parts. Whether the finished joint keeps water out depends on the tape, both parts, edge design and installation conditions. Tell us your component geometry and water exposure so we can assess an appropriate version.
