ADHESIVE SPECIALIST Henkel's new polyurethane (PUR) adhesive Macroplast UK 1340 is said to speed up the process of wind turbine blade bonding.Traditionally, wind turbine blade shells and spars have been bonded using two-component epoxy resins, reports Henkel. One of the major benefits of Macroplast UK 1340 is its faster cure, since PUR-based adhesives react much faster than the epoxy resins used up to now. The two-component PUR adhesive is highly reactive and also produces less reaction heat, considerably reducing the duration and the temperature of the cure phase.
