Patent ID: 8866479

Claim:
A casting compound that is used in casting an electronic module, of a magnetic resonance gradient coil, the casting compound comprising: a resin support material that forms a casting compound support matrix, said matrix including therein: at least one filler comprised of inorganic microparticles, and at least one filler comprised of polymer nanoparticles; whereby the presence of said matrix of inorganic microparticles and polymer nanoparticles, causes said casting compound to flow into and impregnate, without voids and bubbles, existing interstices in a conductor pattern of a magnetic resonance gradient coil and wherein the presence of said matrix of inorganic microparticles and polymer nanoparticles, also makes said casting compound, when cured crack-resistant with an improved critical stress intensity factor K 1c and an improved critical fracture energy G 1c .
