Abstract A novel Sn-Ni-coated Calcium-magnesium Silicate whisker/Nickel powder/
epoxy resin electromagnetic shielding composite coating was prepared according to
the method of paint preparation by using Sn-Ni-coated whisker and nickel powders as
filler and using epoxy resin as binder. The main characteristics and market prospect of
the electromagnetic shielding coating are introduced. The test result indicates that the
shielding effectiveness of the coating is 37.197 ~46.139 dB in the frequency range of
300 kHz~1.5 GHz.
