Abstract. The development of information technologies necessitates the solution of various
problems of information security. Physical means of protecting information processed by computer
objects include radio-absorbing materials. They prevent the interception of information on
electromagnetic radiation and interference in power supply and grounding lines. The general
requirements for radar absorbent coatings are: a high level of attenuation of the reflected signal,
a wide frequency range of operation and the cost-effectiveness of the structure during its
manufacture and operation. The ability of a material to absorb high-frequency radiation depends
on its composition and structure. The materials are quite diverse in their design and structure,
and yet there are averaged performance indicators for the most established RPM groups.
However, not every material can maintain performance under harsh external application conditions.
The paper develops criteria for comparing the following radio-absorbing coatings: conductive
paint (Shielding coating) with water-based silver Water Based Silver Conductive Coating MG
Chemicals 842WB Super Shield™; Water Based Silver Coated Copper Conductive Coating
MG Chemicals 843WB Super Shield™; Water Based Nickel Conductive Coating MG Chemicals
841WB Super Shield™. Their properties and advantages were investigated, and their comparative
analysis was carried out on the basis of the selected criteria.
Key words: shielding coating, conductive paint, radio-absorbing coating, information
security product, electromagnetic and radio frequency interference.
