Self-adhesive grounding strap EB1 with conductive glue for shielded surfaces.
This grounding strap is based on our shielding fabric HNV80 and has been converted to a high-performance self-adhesive grounding strap with electrically conductive glue. Due to the use of HNV80 as a basis, the grounding strap contain also a screen attenuation of 80 dB against high-frequency radio radiation. Thus, this grounding strap EB1 is not only suitable for use as a grounding strap but also for shielding small cracks and can effectively bridge them.
As an alternative to the EB1, the ground strap EB2 is also available, which contains a very strong adhesive with 10 N / cm adhesive bond. However, this adhesive is electrically nonconductive whereby the mounting of this grounding strap must be done under the shielding material. We recommend EB2 only if the application of EB1 is not possible despite the primer due to the nature of the substrate.
Grounding a Faraday cage is mandatory!
The grounding of a Faraday cage is imperative. This is also a legal requirement – an electrically conductive surface must be grounded for reasons of personal safety by law. This is about the mandatory potential equalization (up to the FI circuit breaker) which results from the “requirements for protection against electric shock” and is binding in a DIN VDE regulation.
Processing of self-adhesive ground strap EB1
An electrically conductive grounding strap is an excellent way of electrically connecting a shielded conductive surface and tracks. An alternative to the ground strap is our AF3 additive, which contains electrically conductive carbon fibers. The grounding strap is adhered directly to the processed shielding material for electrical contacting, therefore, the adhesive used is electrically conductive.
This ground strap EB1 is suitable for processing on shielding paints, shielding fabrics and shielding fleeces. EB1 can be glued both under and on the shielding material. For practical reasons, we recommend applying on the shielding material. Due to the electrically conductive filling of the adhesive on the back, the adhesive power is 3 N / cm. EB1 sticks badly on difficult surfaces (eg gypsum plaster boards), therefore these should be pretreated with the GK5 primer.

Schematic representation of grounding a room using EB1 grounding strap
In the case of the shielding paint, the tape is stuck between layer 1 and layer 2. For shielding fabric and shielding fleece after assembly. Basically, the grounding strap is laid so that all surfaces are connected to each other. Whether this connection is done down at the bottom or above just below the ceiling is irrelevant.
All shielded surfaces are always grounded, in the predictive installation are the 6 sides – floor, ceiling and 4 walls. Simply put, the grounding tape is glued all around, so that all 4 walls are connected to each other. Then up to the ceiling and along one side of the ceiling. Then down to the ground and along one side of the floor area. In this simple way, all surfaces are electrically connected together and can be easily connected to the grounded outlet or grounded heating pipe.
This simple theory is usually more complex in practice, for example. Wall breaks, doors, windows, glued parquet floors, etc. In such cases it may be necessary to combine different grounding materials and shielding materials. Use our hotline for advice!
The connection to the earthing must be carried out by the electrician. We recommend checking the electrical installation and grounding. Grounding is only permitted in buildings with TN-S, TT and IT systems. The ground connection on a TN-C system is not possible or connected to a renewal of some parts of the electrical system. Under no circumstances may earthing be carried out in network forms with a combined PEN conductor!More Information
Beware of unreasonable purchase of improper or incorrect use of this grounding straps!
Even if the health risk is rather low, ultimately it’s about nothing but your own safety and in the worst case of your own life. If, for example, a grounding strap is used with conventional industrial adhesive, it acts as an insulating instead of a connecting element, and thus the shielded area remains ungrounded if the grounding strap is used incorrectly and the shielded room can become life-threatening.
This is about the problem when drilling in the electrical line or a nail is hit. Without functioning grounding or equipotential bonding, the electrical current could spread to the entire shielded area via the shank of the drill or nail. Even if the chance for it is very small, it is assumed the highest possible risk. This would be at home current 220 V at 16 A on the wall, with power much more.
The life-threatening accident happens when touching the wall surface by an electric shock. Grounding or potential equalization of shielded, conductive surfaces prevents this.
