Composite Advantage required a strong but lightweight adhesive that could provide permanent adhesion in harsh operating environments, while maintaining elasticity. In addition to its strength SCIGRIP SG230 HV was recommended for its ability to work with a selection of activators to provide working times of 30 to 120 minutes.
"The bridge at Wolf Trap National Park in Vienna, VA needed to be erected quickly at night with only 15 minutes of road closure per span," reports Scott Reeve, President of Composite Advantage, Dayton, Ohio, USA.
"Lighter weight means faster installation and the SG230 HV bonding agent is lightweight, easy to apply in large structures having variable thickness bondlines and remarkably strong."
SG230 HV adhesive is a two component 10:1 mix ratio product designed for bonding composite and other plastic parts with minimal surface preparation. Typically used in marine, transportation and construction applications, and especially suited for bonding large structural parts requiring long working times and for filling deep irregular gaps up to 1.5 inches (39 mm), the adhesive is available in 490 ml catridges, 5 and 50 gallon (19 and 189 litre) bulk containers for application with meter-mix dispense equipment.
