Permabond ES558 Single Part Heat Cure Epoxy Paste

Description

Permabond ES558 is a single-part heat-cure epoxy paste that flows during cure for metal, ferrite, ceramic, and composite bonding. The formula is toughened for impact resistance and gives buyers a no-mix adhesive option for production assemblies that can move through an oven, infrared heat step, or induction process.

Permabond ES558 Benefits

• Single-part packaging removes mix-ratio checks and pot-life waste from repeat production work.
• Heat-cure flow helps the paste wet bond areas during the cure cycle.
• 0.5 mm maximum gap fill supports close-fitting assemblies without needing a two-part paste.
• High shear, peel, and impact performance fits metal, ferrite, ceramic, and composite joints.
• Silver-gray appearance helps operators see placement on many metal and composite surfaces.

This product belongs in applications where parts can tolerate heat and operators need a repeatable epoxy deposit. It is not a room-temperature repair glue. Plan the fixture, heat profile, and bead size before switching from a two-component adhesive.

Common Applications

• Bonding ferrite magnets into metal housings or motor assemblies.
• Joining ceramic, steel, aluminum, zinc, and other close-fitting parts.
• Composite and FRP bonding where heat cure is already part of the process.
• Tooling, wear-tip, and heat-sink assembly work that calls for a one-part epoxy.

Permabond ES558 Technical Details

• Chemistry: epoxy resin single-part paste.
• Appearance: silver-gray.
• Viscosity at 25 C: 100,000 to 300,000 mPa.s according to the technical data sheet.
• Specific gravity: 1.5.
• Maximum gap fill: 0.5 mm, or 0.02 inch.
• Published heat-cure behavior: free flow at high temperature.

Clean parts thoroughly before dispensing. Remove oils, dust, oxides, mold release, and loose coatings, then confirm the cure cycle on actual parts. Heat-cure epoxies can behave differently on thick metal, small ferrites, and composite fixtures because each part absorbs and sheds heat at a different rate.
