In early August, a type of water-based electromagnetic screen paint developed by a research institute of the Logistics Department of the PLA Navy was applied in reforming the electromagnetic shielding of a confidential room in a Shanghai-based unit of the PLA Navy. It has been proved that the paint can basically stop the leakage of electromagnetic waves emitted by the commonly used office equipment such as computer, printer and copier as well as mobile phone in a shielded room, thus it is of great significance to ensuring the security of electromagnetic information communication in a building.

　　The type of electromagnetic screen paint has such an excellent shielding performance that it is suitable for various buildings such as operation command center, computer and precision instrument room and communication center. It is tested and confirmed by the PLA Information Security Detecting and Certification Center that the paint has a sound performance of being capable of shielding against 99.99% of the common electromagnetic wave, hence enjoying the advanced level in China.

　　The briefing has it that the paint can both improve the effect of stopping the leakage of electromagnetic information from important buildings and cut off the jamming of external electromagnetic waves. Compared with traditional metal shielding equipment, the paint can be easily sprayed, coated, brushed on and scraped off the internal surface of plastic housings in different shapes.
