Product Name
Permabond ES550 Heat Cure Epoxy Adhesive 320ml and 15LB Cartridge and Starter Kit
Brief Description
Permabond ES550 is a single-part, heat-cure epoxy paste adhesive that is slump-resistant, meaning it does not flow during the curing process. This adhesive is toughened to provide maximum impact resistance, along with excellent peel and shear strength. It is designed for bonding a wide range of materials, including metals, ferrites, ceramics, composites, and diamonds.
Popular Applications & Uses
- Bonding a diverse array of materials such as metals, ferrites, ceramics, composites, and diamonds.- Heavy wear-and-tear applications, including the bonding of tungsten carbide tools and machinery.- As an alternative to traditional joining methods like welding and brazing.- Applications demanding high strength, resistance to vibration, chemical exposure, and elevated temperatures.
Industries that Commonly Use It
- Aerospace/Defense- Automotive Service/Repair- Chemical Industry- Electrical Services or Products- Energy- Engineering Services- Fabrication- General Manufacturing- Government & Military- Industrial Supply- LED/Electronics- Marine- Medical Device/ Prosthetics- Metal Fabrication- Mold Making/ Casting- Plastic Fabrication- Transportation/ Specialty Vehicle
Special and Unique Features
- Single-part formulation, eliminating the need for mixing and simplifying application.- Heat-cure mechanism for reliable and consistent bonding.- Slump-resistant paste consistency prevents flow during the curing process.- Toughened for maximum impact resistance.- Exhibits excellent peel and shear strength.- Provides excellent resistance to vibration.- Offers high temperature resistance, capable of withstanding brief periods of even higher temperatures (e.g., paint baking, wave soldering).- Good resistance to various chemicals.
Key Properties
- Chemical composition: Epoxy Resin- Appearance: Silver-grey- Physical Form: Paste- Viscosity @ 25°C: 1,000,000 to 2,000,000 mPa.s (cP)- Specific gravity: 1.5- Flow at high temperature: No flow (slump-resistant)- Maximum gap fill: 5 mm (0.2 in)- Cure speed (oven): - 130°C (266°F): 75 minutes - 150°C (300°F): 60 minutes - 170°C (338°F): 40 minutes- Alternative cure methods: Induction, hotplates, infrared lamps, hot-air guns- Shear strength (Steel): 27 – 41 N/mm² (4000 – 6000 psi)- Impact Strength (ASTM D-950): 25-35 KJ/m²- Hardness (ISO868): 80-85 Shore D- Temperature Range (Cured Adhesive): -40°C to 180°C (-40°F to 356°F)
Surface Compatibility
Permabond ES550 is ideal for bonding a wide range of materials, including metals (such as steel, aluminum, and zinc), ferrites, ceramics, composites, and diamonds. For optimal adhesion, surfaces should be clean, dry, and free of grease. Degreasing with suitable solvents like acetone or isopropanol is recommended. Light abrasion with emery cloth can benefit some metals, such as aluminum and its alloys, to remove oxide layers.

Comparison Note
Permabond ES550 stands out as a single-part, heat-cure epoxy adhesive, eliminating the potential for mixing errors common with two-part systems. It is specifically formulated to be slump-resistant, ensuring it stays in place during the curing process. This adhesive offers a robust combination of high impact, peel, and shear strength, coupled with excellent resistance to vibration, chemicals, and high temperatures. These characteristics make it a preferred choice for demanding applications, often serving as a high-performance alternative to traditional mechanical fastening methods like welding and brazing.
