Trying to make some shielding paper for experiment. HSF54 is more shielding than absorption.
I have ordered some EMI absorption sheets (arriving soon). Combine with HSF54 and try out this cocktail shielding method.
Trying to use it inside DAC or Amp to improve shielding between components. e.g. covering the transformer and improve isolation with digital circuits. EMI absorption sheet will be applied inside wall of the case to reduce the internal reflection of EMI.
Not sure yet. I think if you wrap cable with cotton cloth. Paint it with HSF54 will add shielding effect. But you may better buy shielding cloth instead.
This is measurement. Unlike many other audiophile products with no spec, this paint measurement is published and pretty good. Almost straight line -38dB from 30MHz to 18GHz.
