Permabond ES05500007K0101, ES550 1 Part Epoxy, 7Kg Pail
Permabond ES550 — 1-Part Toughened Epoxy Paste, 7kg Pail (ES05500007K0101)
Permabond ES550 (SKU: ES05500007K0101) is a single-part, heat-cure toughened epoxy paste adhesive designed for high-strength structural bonding of metals, ferrites, ceramics, and composites. Slump-resistant — it does not flow during cure, making it suitable for vertical and overhead bonding applications. Toughened formulation delivers maximum impact resistance along with excellent peel and shear strength. Supplied in a 7kg pail for high-volume production applications.

Frequently Asked Questions
How is Permabond ES550 cured?
ES550 is a single-part heat-cure epoxy — it requires elevated temperature to cure and will not cure at room temperature. Refer to the Permabond TDS for the recommended cure schedule (temperature and time). Faster cure cycles are achievable at higher temperatures within the recommended range.
Why is ES550 described as toughened?
Toughened epoxies contain elastomeric or rubber-phase modifiers that absorb impact energy and resist crack propagation. Standard (non-toughened) epoxies are brittle and can fail suddenly under impact or peel loads. ES550's toughened formulation provides significantly higher impact resistance and peel strength, making it suitable for joints subject to vibration, shock, or dynamic loading.
What is the advantage of a slump-resistant paste for bonding?
Slump resistance means the adhesive maintains its position after application and does not flow or sag before or during cure. This is critical for vertical surface bonding, gap-filling applications, and situations where the assembly cannot be repositioned horizontally during cure. ES550's paste consistency allows precise bead placement that stays put through the heat cure cycle.
What substrates does ES550 bond well to?
ES550 is formulated for bonding metals (steel, aluminum, copper, etc.), ferrites (used in magnetic components and transformers), ceramics, and composites. Surface preparation (cleaning, abrading, and priming where appropriate) is recommended for maximum bond strength. Refer to the Permabond TDS for substrate-specific preparation guidance.
Is the 7kg pail compatible with automated dispensing equipment?
The 7kg pail format is designed for high-volume production use and is compatible with pail-fed dispensing systems. Contact MTE Solutions or Permabond for dispensing equipment recommendations compatible with ES550 viscosity and cure requirements.
