Verazol™ | Organic Conductive Polymer
Product Description
Verazol™ is a conductive polymer whose structure is based on conjugated polymers known for their electrical conductivity. Taking advantage of its conductive properties, it is used as an antistatic agent and electrode material. Compounding with various binders can enable printing on various substrates. Soken's proprietary dopant design enables provision of the product in powder, solvent-soluble, and water-soluble forms.
