DSM Launch New Resin Systems

DSM have announced the release of some new resin systems at this years JEC Composites Show in Paris.

Beyone 1 resin is styrene as well as cobalt-free and contains approximately 40% of the raw materials based on renewable resources. This resin is targeted at applications in Building, Infrastructure, Marine and Wind energy.

The low resin viscosity enables easy impregnation and high processing speeds, saving cost and yielding high process output. Close to 40% of the raw materials used for this resin are derived from renewable resources, diminishing considerably the ecological footprint and already clearing the way for continued supply in future when availability of fossil-based raw materials may be reduced.

DSM have also introduced two resin systems for the manufacturing of components and structures through vacuum infusion at high-speed, called Daron 90/B18 and Daron 135/B5 DSM claim these new resin systems allow part manufacturers to reduce production cycle times, and make strong parts with excellent durability and resistance to fatigue. Target markets include Wind Energy, Building & Infrastructure and Marine.

Because of their low inherent viscosity and compatibility with multiple fibre sizing types, glass impregnation with Daron 90/B18 and Daron 135/B5 resin systems is straightforward. The curing can take place at room temperature and is fast. Unlike comparable epoxy resin systems, a great through cure can be achieved by applying only a limited post-cure. The Daron® 90/B18 and Daron® 135/B5 resin systems can give excellent static and dynamic properties both with glass and with carbon fibres.

The market for large structural composite parts has been dominated by epoxy resins for their good fatigue resistance (in spite of epoxy processing limitations and part manufacturing inflexibility). Unsaturated polyester and vinyl ester systems do provide significant processing benefits and with these new resin systems DSM claim to offer the best of both worlds, allowing parts with great mechanical integrity and fatigue resistance to be made at high-speed and low-cost.
