Low VOC unsaturated polyester resins are unsaturated polyester resin bases dissolved in reactive diluents that are non-volatile. These products provide a significant reduction in emissions compared to varnishes and monomer containing polyester resins, with excellent tank stability and viscosities that require little or no adjustment for existing impregnation processes.
A high filling content in the windings is possible resulting in a high technical performance.
