Permabond ET505 Slow Set 60 - 120 minute Toughened Flexible Epoxy Adhesive

Product Name

Permabond ET505 Slow Set 60 - 120 minute Toughened Flexible Epoxy Adhesive

Brief Description

Permabond ET505 is a two-part, 1:1 mixable, semi-flexible, toughened epoxy adhesive. It offers an extended work life of 60-120 minutes, making it highly suitable for larger applications and complex assemblies where adjustment time is crucial. This adhesive forms tough bonds, providing high peel resistance and high shear strength.

Popular Applications & Uses

- Bonding handles onto tools- Aerospace structures- Kitchen countertops- Motor housings and mounting brackets- General assembly applications- Structural bonding applications- Bonding dissimilar substrates

Industries that Commonly Use It

- Aerospace/Defense- Automotive Service/Repair- Cabinet & Woodworking- Chemical Industry- Construction/ Building Services- Countertop- Electrical Services or Products- General Manufacturing- LED/Electronics- Marine- Metal Fabrication- Plastic Fabrication

Special and Unique Features

- Extended work life of 60-120 minutes allows for adjustment and is suitable for larger applications or complex assemblies.- Semi-flexible and toughened, providing high peel and shear strength, and good impact strength.- Achieves full cure at room temperature.- Exhibits good chemical resistance to substances like petrol, oils, and water.- Easy to apply.- Operates effectively in temperatures ranging from -40°C to +80°C.

Key Properties

- Chemical Composition: Epoxy Resin, Amine Hardener- Mix Ratio by Volume: 1:1- Usable / Pot Life @23°C: 1-2 hours (60-120 minutes)- Handling Time @23°C: 3-5 hours- Full Cure @23°C: 72 hours- Shear Strength (mild steel): 18-21 N/mm² (2600-3000 psi)- Peel Strength (aluminum): 60-80 N/25mm (13-18 PIW)- Hardness: 65-75 Shore D- Elongation at Break: 5-10%- Maximum Gap Fill: 2mm (0.08 inches)- Viscosity @25°C: 14,000-28,000 mPa.s (cP) for ET505A, 10,000-25,000 mPa.s (cP) for ET505B- Service Temperature: -40°C to +80°C

Surface Compatibility

Permabond ET505 demonstrates good adhesion to a wide variety of substrates, including:- Wood- Metals (e.g., mild steel, aluminum, brass, cast iron)- Ceramics- Plastics (including some plastics, thermoplastics, thermosets, automotive sheet molded compounds (SMC), and fiberglass reinforced plastics (FRP))- Composites- RubberFor optimal bonding, surfaces should be clean, dry, and grease-free. Light abrasion may enhance adhesion on some metals.

Known backups / known substitutes

Comparison Note

Permabond ET505 is distinguished by its extended work life of 60-120 minutes, which is significantly longer than faster-curing epoxies like Permabond ET510 (with a handling time of 10-15 minutes). This extended open time makes ET505 particularly advantageous for applications that require precise alignment, larger bonding areas, or more complex assembly processes. It provides a semi-flexible, toughened bond with excellent peel and shear strength, along with good impact resistance, ensuring durable and reliable performance.
