RF Shielding Paints

woman-painting-wall-black.jpg

For shielding of walls, ceilings and floors. These RF shielding paints are electro-conductive coatings for the shielding against high-frequency (HF) radiation and/or low-frequency (LF) electric fields. Typical areas of application are laboratories, work spaces, living areas, or general architectoral shielding of buildings.

 
Typical application

Industry: To prevent interception of data from wireless networks, avoiding EMI imigens and to shield sensitive locations such as conference rooms, from eaves dropping.

Science and R&D: Shielding of EMI-sensitive facilities and equipment. 

Medical: Protection of sensitive technical equipment; to protect medical data, integrity of medical devices and protection from other electromagnet interference (EMI) effects.

General Industry: To reduce ingress and egress of electromagnetic interference. Effective in data centers, technical areas, schools, recording/broadcast studios, nurseries, hotel rooms, hospital rooms, etc.

Living areas: Protection against HF-radiation from cell phone towers, TV and radio broadcasting antennas, radar, digital standard cordless telephones and wireless networks, etc. Protection against low-frequency electric fields from power supply lines, etc.
