PAINT COMPOSITION

摘要

This invention relates to the field of an electromagnetic (EM) field shielding paint compositions, in particular, those capable of providing substantially non metallic finish. The paint composition finds particular use in attenuating EM signals that may be used to carry data between communication devices, especially mobile phone and wi-fi devices. EM field shielding paints are typically available in jet-black or bright metallic finishes and usually possess limited scratch & abrasion resistance. The paint composition provides a one-pot solution to furnish a composition which has the visual appearance of a domestic type paint i.e. one with a non-metallic finish, with the ability to shield electromagnetic radiation. The composition comprises a supported metallic flake and a pigment, which have been provided in a narrowly defined range to furnish a desirable non-metallic appearance and possess electromagnetic shielding properties.
