Antistatic properties of clear coatings through the use of special additives

In recent work, researchers have evaluated different substances to study their ability to produce anti-static effects, especially in UV-transparent coatings.
they developed a method to evaluate the suitability of anti-static additives by studying the position of anti-static additives in the coating substitum, as well as the position of the coating resistance and the resulting coating properties. We compared a range of chemicals, from traditional season salts to polymer materials and pigments, to give anti-static effects to better understand their performance in coatings and to understand their benefits or

additives help reduce surface resistance, thus increasing the potential for anti-static properties. Scientists have found the most effective way to reduce resistance to ionic liquids and conductive pigments, but they have not been able to target surfaces that require anti-static behavior.
the most effective additives on the surface of
anti-static behavior, but they rely mainly on improved hydro-hydrogenicity, resulting in reduced hardness of the coating and a tendency to leach out of the coating. The modified seasonal ammonium salt (seasonal ammonium cation material) with PDMS (polydymethane) provides the strongest surface affinity, but this anti-static behavior is reduced compared to low molecular similaries due to the low molar concentration of the active group.
researchers believe that formulat designers can use this work to better design additives to find the right place in the coating to avoid waste and side effects, and to solve persistent problems through cross-linking.
the study has been published in the Journal of Coating Technology and Research, Volume 17 (2020).
