The two-part Core-Bond system product range from Scott Bader North America (formerly Scott Bader-ATC) has recently been awarded Product Design Assessment (PDA) certification for composite core installation by the American Bureau of Shipping (ABS) for marine and offshore applications.
According to Scott Bader, the three Core-Bond hand-mixed adhesive grades (B70/ B72 / B73) and the two spray grades (B71/ B75), plus the ATC priming and sealing resin ortho and ortho/DCPD options, developed for this application system, have all been awarded a PDA certificate for sandwich core construction of FRP composite parts by hand lay-up or vacuum infusion, which can be installed on an ABS classed vessel, Mobile Offshore Drilling Unit (MODU) or offshore facility.
Jean-Pascal Schroeder, COO of Scott Bader North America commented, “This product design accreditation from ABS for our Core-Bond system is a major feather in our caps as the marine and offshore industry is one of the toughest sectors to meet. This prestigious application approval underpins our focus on producing high performance, high quality technical products for composite manufacturers.”
Scott Bader explains that Core-Bond is a long established system for FRP boatbuilding, with an early application success back in the mid 80s being its use for foam core installation on US Navy personnel boats. Core-Bond was initially developed for synthetic core foams, but later also proved ideal for bonding in balsa wood cores. The two-part system works by having the Core-Bond adhesive and priming resin cure together at about the same time; the priming resin also serves to fill the voids between the cuts in the core or the bleeder holes in plain cores. The Core-Bond range has grade options for either a BPO or MEKP catalyst system, and Scott Bader North America also produces ‘Regular’, ‘Summer’ and ‘Winter’ versions in order to provide moulders with a consistent, optimised gel-time of around 50-60 minutes all year round at both higher and lower ambient temperatures.
