Composites adhesives


SCIGRIP (Tyne and Wear, U.K.) is launching at JEC Europe 2013 an enhanced product for bonding dicyclopentadiene (DCPD) composites. As a result of its developmental work with SG600, a methyl methacrylate (MMA) structural adhesive, SCIGRIP has produced an advanced product that is suitable for bonding many difficult substrates, including grades of DCPD. SCIGRIP says many grades of DCPD adhered successfully with SG600 without time-consuming preparation techniques such as flame treatment. SG600 is cold curing to produce tough and fatigue-resistant bonds and also features ratio adjustable cure times and rheology compatible with robotic application. SG600 has also performed well in trials bonding ABS, PVC and SMC as well as traditional PE, VE or epoxy composites. SCIGRIP will also feature its 10:1 MMA range, now in full EU and USA production. These include SG230HV, the high-gap-fill, low-exotherm MMA for large composite component assembly, and SG300, popular in many transport sectors for tough bonding of composites and metals without primer.
