Abstract
A formulation based on two components, which, when added to items produced with epoxy vinyl ester or unsaturated polyester resin, provides the formulation with electric charge dissipation and/or antistatic characteristics, maintaining the mechanical characteristics thereof and the possibility of dyeing the material in all of the possible colour ranges includes a first component which is an active substance which is an ionic salt that allows ion mobility. The cation is a compound based on the (R4)N,N,N-trialkyl-alkyl-ol-ammonium species, as it is or derivatised on the OH group, and a system that supports said active substance. This additive or formulation added to epoxy vinyl ester or unsaturated polyester resin can be used in the production of agglomerated stone, gel coat, sheet moulding composite or bulk moulding composite.
