Fillers and additives can be added to Polyester and Epoxy resin to extend the resin and impart specific properties to the resin mix. The amount of filler that can be added depends on the viscosity of the resin and the size of the filler particles, generally, the smaller the particle size the less filler can be added to give a workable mixture. It is best to add fillers and additives just before using the mixture to minimize any settlement that may occur.
