Solvay FM® 490A Core Splice Adhesive
Categories: Polymer; Adhesive; Thermoset; Epoxy; Epoxy Adhesive

Material Notes: Description: 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.

Features & Benefits:

  • Use temperature ranging from -67°F to 350°F (-55°C to 177°C)
  • Wide curing window: 225°F to 350°F (107°C to 177°C)
  • Uniform cell structure: ambient to 10 inches of mercury vacuum
  • Achieves uniform expansion independent of heat-up rate 1°F to 10°F/minute (0.6°C to 5.6°C/minute)
  • Non-asbestos, no metallic fillers
  • Radar transparent
Applications:
  • Honeycomb splicing
  • Localized reinforcement
  • Bonding of edge members and inserts
