Material Notes:

Redux 641 is a high temperature modified epoxy film adhesive curing at 350°F. It is suitable for bonding metal to metal and for sandwich structures where operating temperatures are experienced up to 350°F for short periods, or 300°F for continuous operation. Redux 641 is a hot melt film which is free from solvents and consequently has a very low volatile content.Features: Cures in 1 hour at 350°F; Good hot lap shear performance up to 300°F; Good peel performance in sandwich structures at temperatures up to 300°F; Excellent metal-metal peel properties; Excellent drape and handleability; Very low volatile content.Applications: Metal to metal bonding; Sandwich constructions with a variety of skins and cores.
