FIELD: physics.
SUBSTANCE: composite joint filler with resistivity of not less than 10 kOhm·cm contains the following (pts. vol): polyurethane elastomer with Shore hardness of not less than 85 units - 65-85 and iron powder with purity of not less than 99.98% on mass and fraction of up to 100 mcm - 15-35.
EFFECT: lower magnetic field strength in the joint clearance and avoiding possibility of short circuiting with metal particles.
