Antistatic coatings for wood-floorings by imidazolium salt-based ionic liquids

The tendency to electrostatic charge is at least an unpleasant property, which is unfortunately typical for many floors. Ionic liquids represent a good alternative to overcome the disadvantages from typical antistatic agents like worse leaching behavior and at least haze in the coating. 1-Allyl-3-alkyllimidazolium salts have been evaluated as antistatic additives in a UV-curing coating for parquet flooring. 1-Allyl-3-methyllimidazolium chloride has been identified to exhibit the highest activity and a minimized leaching. The measured body voltage regarding EN 1815 was below ≤2.0 kV and the resistivity regarding EN 1081 below 1010 Ω. In addition, there is a synergistic effect with conductive and transparent indium-tin-oxide pigment particles.
