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. It 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. Typical applications include bonding of inserts or edge members to core and localized reinforcement of honeycomb core where increased shear strength is required. Because FM 490A core splice adhesive contains no metallic fillers it is appropriate for applications requiring radar transparency. Suggested Applications: Honeycomb splicing Localized reinforcement Bonding of edge members and inserts
