Adheco offers a bonding and sealing solution that can be used in place of welding or brazing joints: Permabond ES558. This single-part epoxy adhesive can simplify production lines and reduce the hazards associated with labour-intensive welding processes, making it a top choice for applications that require a strong bond for metal components.
Key features and advantages
One of the major benefits of Permabond ES558 is its excellent strength and durability. The adhesive is cured by oven, infrared or induction heating. When heated for curing, it flows like solder and wicks into small gaps where it will cure, forming a high strength, durable bond and a 100 per cent seal between components. In addition, ES558 is rubber toughened, which gives it a high peel and shear strength and good impact resistance, as well as better stress distribution. Plus, it can go through a paint bake oven cycle and withstand solder reflow processing thanks to its excellent thermal resistance. ES558 also offers resistance to vibration and chemicals.
This adhesive is also easy to apply, as no mixing or measuring is required. It comes in a convenient 320-millilitre cartridge, which fits in a regular caulking gun, and has its own nozzle, which can be cut to an appropriate bead size that will cover the bond area. The user simply applies the adhesive to a clean, dry and grease-free surface before assembling the parts with sufficient pressure to ensure the adhesive spreads to cover the entire bond area. Following this, a jig or clamp is used to prevent parts from moving during heat cure.
The Permabond ES558 adhesive is ideal for use on a wide range of materials. It is particularly suited for bonding aluminum, steel, copper and most other metals, tungsten carbide, magnets, ferrites, ceramic materials, some plastics and composite materials.
