DSM Composite Resins (Schaffhausen, Switzerland) has developed Synolite 1790-G-3, an unsaturated polyester resin system specifically formulated for wind turbine blade applications. The new high-performance resin reportedly was developed and tested in cooperation with wind industry manufacturers. The low-viscosity resin system is designed for vacuum infusion and is said to offer a range of performance improvements over other commonly used unsaturated polyester and epoxy resin solutions. Reported benefits include better wetout, room temperature cure with no necessity for postcure, very low exotherm and fast through-cure in thin-laminate parts. The new specialty resin is commercially available and will be produced in China and Europe.
