Because of its special structure WACKER® L 066 exhibits unique high surface activity, which allows it to wet and spread effectively on nearly any surface.

WACKER® L 066 is therefore primarily used for lowering the surface tension of aqueous and non-aqueous solutions, as a highly effective wetting agent and for hydrophilic treatment of numerous materials and surfaces.

Specific features of WACKER® L 066

  • Fluid
  • WACKER® L 066 enables efficient wetting and improves the effectiveness of water- based herbicides, insecticides and fungicides (used in concentrations between 0.05-0.25%).
  • WACKER® L 066 significantly improves the penetration of ironsulfate to prevent/cure iron chlorosis and ofmagnesium chlorate in cotton defoliation (used in concentrations between 0.05-0.25%).
  • WACKER® L 066 improves wetting of hydrophobic surfaces, e.g. in the textile industry.
  • Hydrophilic treatment of hydrophobic surfaces like plastics (enhanced wetting and antistatic effect).
