This modified epoxy adhesive is available in sheet form and can be cured through free or restrained foaming processes. It operates effectively at temperatures between 225 to 350 degrees F and is suitable for applications like honeycomb splicing and bonding, while ensuring radar transparency due to the absence of metallic fillers.This modified epoxy adhesive is available in shee

Overview
FM® 490A core splice adhesive is a modified epoxy material supplied in sheet form that may be cured in place by either free foaming or restrained foaming processes. FM® 490A may be processed at any temperature ranging from 225 to 350 degrees F (107 to 177 degrees C). It is specifically designed to minimize variation in cell structure induced by typical process variables such as heat up rates and vacuum conditions. Since FM® 490A core splice adhesive contains no metallic fillers, it is appropriate for applications requiring radar transparency. Typical applications for FM® 490A include honeycomb splicing, bonding of inserts or edge members to core and localized reinforcement of honeycomb core where increased shear strength is required.
