SCIGRIP’s SG230 HV Methacrylate Adhesive Strengthens Aging Marine and Land Infrastructures

11 December 2012

An Australian company specialising in composite repair structures for marine pilings recently selected SCIGRIP’s SG230 HV (High Viscosity) methacrylate adhesives the bonding agent in its PileJax pile encasement repair system.

The selection came after rigorous testing by the University of Southern Queensland Structural Composites Faculty, National Association of Testing Authorities (NATA) certified laboratories and a specialist composite facility in the US. Brisbane-based Joinlox required an adhesive that could provide strong durable joints for assembling composite forms in a variety of chemical environments, including permanent and complete immersion in salt water. In addition to the ability to withstand prolonged salt water exposure, SCIGRIP’s SG230 HV was also recommended for its proven ability to adhere to vertical or overhead surfaces without sliding or sagging – and cure completely under water.

“The PileJax system is designed to be a heavy duty structural component in the rehabilitation of aging wharf and bridge piles,” said Joinlox CEO, John Pettigrew. “SCIGRIP’s SG230 HV adhesive provides our rapid-fit composite jacket with a bonding agent that is lightweight, easy to apply and exceedingly strong.”

SCIGRIP’s SG230 HV methacrylate adhesive is a two-component, 10:1 mix ratio product for bonding composite and other plastic parts with minimal surface preparation. The adhesive is designed to work with a selection of activators, providing a wide range of working times ranging from 30 to 120 minutes. 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 39 mm, the SG230 HV adhesive is available in 490 ml cartridges; 19- and 189-liter bulk containers for application with meter-mix dispense equipment.

“At SCIGRIP we continually strive to find smart adhesive solutions to difficult bonding problems in collaboration with customers, such as Joinlox, who need solutions to their product development challenges,” said Manny Tesfaye, Director of Global Technical Services. “The unique advantages of the SG230 HV enabled Joinlox to offer the Pilejax encasement system as a cost effective method of repairing and strengthening marine and land infrastructure.”
