Product Description
Araldite® AW 8680 Resin / Hardener HW 8680 is a general-purpose, two-part polyurethane adhesive designed for bonding a wide variety of substrates. It provides a long open time and cures to form a highly flexible bond, making it particularly well suited for primed metals and plastics such as polycarbonate and nylon.
Key features
- Excellent flexibility: Delivers highly flexible bonds with an elongation of 225% once fully cured.
- Convenient processing: Features an easy-to-use 1:1 mix ratio by volume for straightforward application.
- Extended open time: Offers a 15-minute pot life at 77°F (25°C), providing ample time for assembly.
Applications / Suitable for
- General plastic bonding.
- Bonding polycarbonate and nylon headlamps.
- Primed metal bonding applications.
