FM® 300 is a 350ºF (177ºC) curing modified epoxy film adhesive available with three different moisture-resistant polyester carriers, and is designed for bonding metal-to-metal and sandwich composite structures. To achieve ultimate environmental resistance in bonding aluminum details, use pre-cured BR® 127 primer with FM® 300 film adhesive.

Extensively used as a surface finished ply on composite materials’ outside layers, FM® 300 film adhesive has unique properties which drastically reduce, and in some cases virtually eliminate, time-consuming sanding and filling operations.

FM® 300 film adhesive has high elongation and toughness with high ultimate shear strength. This makes it particularly suitable for redistributing the high shear stress concentrations of graphite epoxy-to-metal bonds, and allows it to accommodate the low inter-laminar shear strength of the composite.
