FM® 355 is a 350°F (177°C) curing epoxy adhesive formulated to maximize toughness in applications requiring hot/wet performance up to 350°F (177°C). It contains no asbestos or aluminum fillers, which is desirable for radar transparent applications. FM® 355 adhesive film is supported with a lightweight nylon carrier and will cure at 350°F (177°C) in one hour. For composite bonding applications, FM® 355 adhesive provides excellent toughness and shear strength properties. It was developed for co-cure as well as secondary bonding applications. In addition FM® 355 adhesive can be co-cured with epoxy or bismaleimide composite systems requiring post-cures of up to 475°F (246°C).
