Polyester resins are impregnation resins, based on unsaturated polyesters with reactive monomers. The monomers (styrene, vinyl toluene, diallyphthalate) are also used to dilute the base and then react with it at high temperature.
We can offer you varnishes and resins adapted to all types of processing (single dip, drop by drop, dip and roll, dip under vacuum and pressure, …).
