Polyurethane Adhesive

Mon, 11/14/2011 - 6:50am

Henkel (Rocky Hill, CT) has introduced a new high-performance polyurethane adhesive that prevents crack propagation on wind blades and delivers excellent long-term structural integrity on turbine assemblies. The first ever Germanischer Lloyd-approved polyurethane adhesive, Macroplast UK 1340 cures rapidly at room temperature, reduces production costs, and shortens production cycles by 15 to 30 percent. Macroplast UK 1340 has demonstrated a tensile shear strength exceeding 20 megapascals at -40 to +80 degrees C. The adhesive has demonstrated superior dynamic fatigue strength, which allows wind blades to handle deflection, dynamic load, and stress on the adhesive bond line and reduces the risk of stress cracking.
