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°F to 350°F (107°C to 177°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.
