Solvay expands range of FusePly Covalent bonding tech

Solvay, a global leader in specialty materials, has expanded its range of FusePly chemical bonding technology with a second product, FusePly 250, designed to bond composite structures at 250°F and higher.

The new product complements the previous FusePly 100 grade, introduced in 2018 which has now been renamed FusePly 350 to reflect its compatibility with 350°F cure film adhesives. Both grades offer step-change bonding performance and durability and can easily be integrated into existing manufacturing processes as an upgrade for traditional surface preparation methods.

FusePly is a breakthrough composite bonding technology resulting in covalent bonds between adhesives and composite structures. While it handles and processes like a conventional peel ply product, it creates a reliable chemically functionalised composite surface which eliminates time and labour-intensive surface preparation steps and assembly processes.

“The reliability and robustness of bonded structures are a top priority for users of composites in safety critical applications in aerospace and other demanding markets” said Stephen Heinz, VP research and innovation for Solvay’s global Composite Materials business unit. “We developed FusePly, a fundamentally new bonding approach, to meet the needs of leading aircraft OEMs and enable them to take full advantage of composites for lighter, stronger structures.”
