DSM has recently released a second generation of unsaturated polyester resins in the Synolite 1777 series. These resins are now penetrating the wind turbine blade market.
When combined with glass fiber reinforcement and the right sizing, Synolite 1777 resin has very high mechanical properties. Blade manufacturers supplying the Chinese market are now discovering the advantages. As well as a lower cost of the material, this new generation of unsaturated polyester resin is much lower in viscosity compared to epoxy and does not require post-curing. Synolite 1777 resins can be produced locally in DSM's Nanjing plant. DSM has recently launched a new sizing for the glass fiber reinforcement of the resin for wind-turbine blades. Neoxil 728 sizing will be produced at DSM's dedicated Neoxil sizing plant in Shanghai, China, in Q1, 2008 and can also be produced in the Neoxil plant in Filago, Italy.
