This brush is made with a mixture of Thunderon, a conductive filament, and Goat hair. Thunderon is a very fine (0.0015 diameter) acrylic fiber chemically bonded with copper sulfide. The special fiber will dissipate a charge on any electrically charged surface. The surface resistivity of Thunderon is 10-2ë©/cm. The plastic handle is dissipative with a surface resistivity of 105ë©/cm.
Note: Conductive fibers are NOT recommended for use with unencapsulated electronic microcircuits. Minute pieces of conductive material have been known to cause short circuits.
