ISOBOND SR 740

Product description:

The ISOBOND SR 740 system is a next-generation structural epoxy adhesive specifically formulated for producing bonded joints up to 25 mm thick.

Thanks to its high toughness and excellent fatigue resistance, it is a preferred choice for structural bonding applications subjected to significant dynamic loads.

Designed for multi-material applications, it offers low toxicity, a high glass transition temperature, and is currently undergoing Lloyd’s Register certification. Also available in a 400 ml two-component cartridge for simplified application.
