Antistatic powder coating compositions and their use

摘要

This invention relates to a powder coating composition comprising a mixture of conventional, possibly coloured, non-conductive thermosetting powder coating compositions with highly conductive thermosetting powder coating compositions so as to produce a coating having an electrical surface resistance of less than 10<10 >Omega (ohm), preferably of less than 10<8 >Omega (ohm), and to the substrates coated therewith. This invention also relates to using a mixture of non-conductive and conductive powder coating compositions to produce a coated surface having an electrical surface resistance sufficiently low to possess antistatic properties.
