Scott-Bader, a global chemical company developing a wide range of synthetic resins and polymers, has announced that the two-part Core-Bond system product range from Scott Bader North America has bagged Product Design Assessment (PDA) certification for composite core installation by the American Bureau of Shipping (ABS) for marine and offshore applications.

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 fibre- reinforced polymer (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.

Core-Bond is a long established system for FRP boatbuilding, with an early application in 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 balsawood 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.

Jean-Pascal Schroeder, COO of Scott Bader North America said, “The 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. The prestigious application approval underpins our focus on producing high performance, high quality technical products for composite manufacturers.”

The Core-Bond range along with the marine grade laminating resins, gelcoats, bonding pastes, structural adhesives, and tooling products for FRP boat building will be shown at The International Boatbuilders Exhibition & Conference (IBEX) in Tampa, Florida from October 4 to 6, 2016, in booth #944.
