METHOD OF MAKING RADAR ABSORBING COMPOUND Russian patent published in 2025 - IPC C09K3/10 C08L83/00 

FIELD: performing operations.

SUBSTANCE: invention relates to methods of producing a multicomponent radar-absorbing compound intended for filling radioelectronic products operating in high-radiation areas. Disclosed is a method of making a radar-absorbing compound containing a dielectric binder – a two-component silicone compound of the type Pentelast-711 grade A – paste K, and a cold curing catalyst Penta-68 O, which differs from known designs in that, as the electromagnetic radiation absorbing filler, a mixture of three components of a powder ferrite fraction is used: 6 weight parts "6000 NM", 3 weight parts "30 VN", 4 weight parts "200 VNS", wherein the order of performing the operations is as follows: put the required amount of paste K into the container and weigh the contents on the scales, taking this weight minus the weight of container as 100%; calculate and weigh 6 parts of the cold curing catalyst Penta-68 O in a separate container; prepare a ferrite powder mixture based on the following ratios: 6 parts of "6000 NM", 3 parts of "30 VN", 4 parts of "200 VNS", one part – 3 cm³, thoroughly mix the powder mixture; thoroughly mix the contents of the K paste container and 6 parts of the cold curing catalyst Penta-68 O using a mixer; prepared ferrite powder mixture is placed into the content of the compound, mixed thoroughly, the compound is ready for pouring; pouring prepared compound into prepared products, excluding formation of voids; poured products are held for at least 10 hours at temperature of 23 °C for curing, after which the products are ready for use.

EFFECT: high resistance to radiation, high resistance to tropical climate factors, high heat resistance while maintaining radio characteristics.
