DSM have introduced a new resin system that helps pultrusion companies to make profiles and structures at high-speed and with process robustness.
This new product (Daron 220) can be easily tuned for a variety of applications, and used as single resin or as part of a two-component system. Because of its low viscosity, glass fibre impregnation is straightforward. This allows making components with great strength, both with glass and carbon fibre. Moreover, the parts can demonstrate excellent heat resistance.
When used as part of a two-component system the glass transition temperature of the resin can be as high as 220 °C, way above the glass transition temperature of conventional Vinyl ester resins. The chemistry of the resin enables running pultrusion lines at much higher speed vs. traditional high heat epoxy resins.
