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.

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.”

The Core-Bond range along with the marine grade laminating resins, gelcoats, bonding pastes, structural adhesives and tooling products for FRP boat building are being shown at The International Boatbuilders Exhibition & Conference (IBEX) in Tampa, Florida from October 4-6, 2016, where Scott Bader North America is exhibiting (booth #944).

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 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. 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 molders with a consistent, optimized gel-time of around 50-60 minutes all year round at both higher and lower ambient temperatures.  

In addition to the Core-Bond range, the Scott Bader plant in Drummondville, Canada manufactures a wide range of polyester and vinyl ester based pastes and compounds for tooling and fairing production, compression and displacement molding, bonding, repair and protection, supplied to the global composites market place. Scott Bader North America’s extended product portfolio includes Scott Bader’s urethane acrylate Crestomer® and primerless Crestabond® MMA structural adhesive ranges, and high performance Crestapol® acrylic resins for producing advanced performance, lightweight and fire retardant FRP composite parts.

ABS, with 200 offices in 70 countries, is one of the leading marine and offshore classification societies for the marine, offshore energy and gas industries. Its global network of surveyors, engineers and technical specialists focus on safety and understanding the long-term impact of what is used by these industries in order to protect life, property and the environment.
