Permabond ES558 1-Part Heat-Cure Epoxy, Cartridge and Starter Kit

Product Name

Permabond ES558 1-Part Heat-Cure Epoxy, Cartridge and Starter Kit

Brief Description

Permabond ES558 is a single-part, heat-cure epoxy adhesive paste engineered for high-strength, durable bonding and sealing across a variety of materials, including metals, ceramics, and composites. This toughened adhesive flows like solder when heated, wicking into small gaps before curing to form a robust, impact-resistant bond.

Popular Applications & Uses

- Bonding and sealing metal components.- Sealing heat exchanger tubes.- Replacing welding or brazing joints in manufacturing processes.- Bonding tungsten carbide for tools and machinery wear tips.- Applications requiring high temperature and chemical resistance.- Can withstand solder reflow processing, making it suitable for certain electronic applications.

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- Plastic Fabrication- Transportation/ Specialty Vehicle

Special and Unique Features

- Single-part epoxy formulation, eliminating the need for mixing.- Cures rapidly with heat (oven, infra-red, or induction heating).- Flows like solder when heated, allowing it to wick into small, pre-assembled joints.- Rubber-toughened for maximum impact resistance.- Exhibits high peel and shear strength.- Offers excellent resistance to vibration.- Provides high temperature resistance, capable of withstanding paint bake oven cycles and solder reflow.- Possesses good resistance to various chemicals.- Creates a 100% seal between components.- Ensures better stress distribution compared to traditional joining methods like welding or brazing.

Key Properties

- Chemical Composition: Epoxy Resin.- Appearance: Silver-grey.- Viscosity: 100,000 - 300,000 mPa.s (paste).- Maximum Gap Fill: 0.5 mm.- Cure Speed: Approximately 60 minutes at 130°C or 45 minutes at 150°C (actual times vary with assembly size).- Shear Strength (Steel): 27-41 N/mm².- Hardness: 80 Shore D.- Operating Temperature Range: -40°C to +180°C.- Solubility: Insoluble in water, soluble in organic solvents.

Surface Compatibility

- Aluminium (particularly effective for heat exchanger tube sealing).- Steel, copper, and most other metals.- Tungsten carbide.- Magnets and ferrites.- Ceramic materials.- Some plastics.- Composite materials.- Recommended surface preparation includes degreasing with solvents like acetone or isopropanol, and light abrasion for certain metals to remove oxide layers.

Known backups / known substitutes

- Loctite E-310 (Henkel) - a 1-part, heat-cure epoxy.- Loctite E-309 (Henkel) - a 1-part, heat-cure epoxy.- Permabond ES550 - a similar 1-part, heat-cure epoxy paste from the same manufacturer.- Other 1-part heat-cure epoxies with comparable performance characteristics for structural bonding.

Comparison Note

Permabond ES558 stands out as a single-part, heat-cure epoxy that streamlines production by eliminating the need for mixing and offering a safer alternative to welding or brazing. Its unique ability to flow like solder when heated, combined with a rubber-toughened formulation, ensures high impact and peel strength, providing superior stress distribution and an aesthetically pleasing finish for demanding industrial applications.
