Description: FusePly® 350 is a technology designed to achieve reliable bonding through creating covalent chemical bonding interface in adhesive joints of pre-cured composite structures using either conventional co-bonding or secondary bonding processes. 



FusePly® 350 is compatible with most commercial 350°F cure epoxy-based prepregs and adhesive systems and requires no additional processing steps, such as sanding or solvent wiping prior to bonding. 


About FusePly® range:

Through patented technology, FusePly® is able to bring a new level of reliability to the bonding process by creating a chemically-active surface for bonding, rather than just a mechanically-prepared surface as with traditional peel plies, sanding, or plasma surface treatment. 


FusePly® deliver structural performance and dependability of co-cured bonded structures with the convenience and flexibility from using pre-cured composites. FusePly® was designed to be processed and handled just like conventional peel ply surface treatments, allowing for seamless insertion of the technology into a manufacturing shop. The system, supplied in film form with a polyester peel ply fabric, is engineered to offer a clean, fiber-free surface for composite bonding applications.
