    摘要: Improved compositions are disclosed which are useful in providing a conductive layer of coating on a surface to provide protection against harmful electrostatic discharges. Also disclosed are compositions useful in absorbing and dissipating mechanical and electromagnetic energy and preventing electrostatic build-up; these compositions also provide electromagnetic compatability. The compositions contain elemental carbon and a polymeric matrix or binder. The improvement comprises employing a unique ground calcined, coal-based coke which approaches graphite in terms of its performance as a conductive additive or pigment but which does not possess the disadvantages associated with the use of graphite.The unique coke employed in the compositions and methods of the present invention has a level of graphitic structure which approaches that of a true graphite. This level of graphitization can be most easily recognized by utilizing x-ray powder diffraction. More specifically, when the value of E.sub.c or the inverse carbon peak width (the 002 peak) is measured for this material using Mo K.sub..alpha. radiation (.lambda.=0.71 .ANG.), the value is in the range of about 27 to about 80, and preferably about 28 to about 75.The final compositions employ a polymer resin or matrix system as a binder.The invention also relates to the method of applying the compositions to protect the article and reinforce the substrate, and the resulting coated articles, particularly containers for shipping and storage of electronic components and magnetic information-storage materials. The conductive coating may also add strength to the containers. The compositions may also be used to absorb both mechanical and electromagnetic energy thus providing EMC, and dissipate static electricity, thus preventing electrical static build-up.

    摘要: A new copper dispersion coating composition particularly useful as a copper shielding coating for plastic enclosures to protect electronic equipment from electromagnetic interference (EMI). The coating maintains high electrical conductivity even after exposure to heat, humidity or salt spray. The coating composition may also be used as a one-coat air dry system that is spray applied and needs no protective overcoat.

    摘要: Disclosed are improved compositions useful in providing a conductive layer or coating on or within a conductor. The compositions contain elemental carbon and a polymeric matrix or binder. The improvement comprises employing a unique ground calcined, coal-based coke which approaches graphite in terms of its performance as a conductive additive or pigment but does not possess the disadvantages associated with the use of graphite.The unique coke employed in the compositions and methods of the present invention has a significant level of graphitic structure. This level of graphitization can be most easily recognized by utilizing x-ray powder diffraction. More specifically, when the value of E.sub.c or the inverse peak width (using the 002 peak) is measured for this material using Mo K.alpha. radiation (.lambda.=0.71 .ANG.), the value is in the range of about 27 to about 80, and preferably about 28 to about 75.The final compositions employ a polymer resin or matrix system as a binder, preferably an acrylic emulsion or a fluoroelastomer. They are particularly useful as a sheath coating for elongated conductors such as automobile ignition cables.The invention also relates to the method of applying the compositions to the conductors, and the resulting coated conductor.
