    Adhesive solution for DCPD bonding


    SCIGRIP has launched an enhanced product for bonding dicyclopentadiene (DCPD) composites. The company claims that different grades of DCPD can be adhered successfully using SG600 without the need for time-consuming preparation techniques such as flame treatment.SG600 is cold curing and also features ratio-adjustable cure times and rheology compatible with robotic ...

    Editor's Note: Cutting edge


    Making ‘cuts’ seems to be the automotive manufacturing solution of the moment; whether it’s cutting weight from a vehicle, perhaps most dramatically exemplified by the new Range Rover, or cutting production in the case of many of the European OEMs in the face of a lifeless market. Lightweighting vehicles (a ...
