A line of conductive gelcoats from BÜFA Composite Systems, with colored and glossy surfaces, is changing the perception of conductive gelcoats, according to OCSiAl. Surface resistivity as low as 10^3 Ω/sq in polyester-based gelcoats can be achieved by adding a tiny amount of TUBALL single wall carbon nanotubes, OCsiAl noted.
“Application of carbon black or graphite as a conductive additive negatively affects the original color, resulting in a black surface, or dark grey at best. That strong correlation has resulted in the stereotype about conductivity always being associated with a black color,” said Elmar Greiff, project leader Nanocomposites, BÜFA Composite Systems. “We now make conductive gelcoats with previously unachievable color shades, including almost white.”
BÜFA Composite Systems developed a tooling gelcoat with TUBALL nanotubes. Its surface resistivity of 10^6 Ω/sq is low enough to prevent any accumulation of electric charge.
