Electrically conducting glass strands and structures comprising such strands

A glass strand or glass strand structure coated with an electrically conducting coating composition, the amount of said electrically conducting coating composition representing at least 20% and at most 200% (as % by weight of solid matter) of a glass strand or glass strand structural body, said electrically conducting coating composition comprising as % by weight of solid matter:

• 6 to 50% of a film-forming agent, wherein the film-forming agent is a polyvinylpyrrolidone, a poly(vinyl alcohol), a styrene polymer, a poly(vinyl chloride), a polyurethane or mixture thereof,
• 5 to 40% of at least one compound chosen from plasticizing agents, surface-active agents and/or dispersing agents,
• 44 to 75% of electrically conducting particles,
• 0 to 10% of a doping agent,
• 0 to 10% of a thickening agent,
• 0 to 15% of additives,
• wherein the electrically conducting particles consist of a mixture of (A) 2.5 to 45% by weight of solid matter of graphite particles having a size of from 10 to 100 μm, at least 5% by weight of the graphite particles are in the form of flakes or needles with an aspect ratio of greater than or equal to 5;
• (B) 0 to 45% by weight of solid matter of graphite particles having a size of less than 10 μm, and (C) 2.5 to 45% by weight of solid matter of carbon black particles having a size of less than 1 μm.
