Deuteron® LE 50 serves as a conductivity additive formulated with tetraalkylammonium ethyl sulfate. These anti-static additives enable the adjustment of surface and volume resistivity within diverse systems. Their efficacy primarily relies on surface migration and the ionic characteristics of the cations to achieve the desired effects on electrical properties.

Product Highlights
  • Deuteron® LE 50 is conductivity additives based on tetraalkylammonium ethyl sulfate. The use of our anti-static additives allows the adjustment of the surface and volume resistivity in various systems. The effect of Deuteron®’s anti-static additives is mainly based on surface migration and the ionic character of the cations.
  • Deuteron® LE 50 is are liquid products diluted in 1-Butanol. Due to their cationic character and the associated extremely high polarity, the products dissolved in butanol considerably reduce the electrical resistance of organic solvents and their mixtures.
  • The products are miscible in all solvent mixtures commonly used in coatings, partly slight turbidity can occur. Because of its lower active content Deuteron® LE 50 carries a less critical GHS labeling.

Application and Dosage Information
  • Deuteron® LE 50 is mainly developed to adjust the resistivity of electrostatic spray paints. They can be used in air-drying as well as forced-drying primers and top coats. For use in isocyanate-systems the proportion of hydroxy groups of the Butanol can be taken in consideration.


  • Deuteron® LE 50: approx. 0.3 % to 4 %.
  • The exact quantities to be used depend on the system and must be determined individually for the intended application.


  • Deuteron® LE products can be added to the system at any time during the production process or they can be used as post addition additives to further adjust resistivity.
