Spabond 445 Slow is a high-performance, toughened epoxy structural adhesive system developed by Gurit. It is specifically designed for bonding large, complex structures with irregular geometries or vertical gap-filling requirements.The Slow variant utilizes the Spabond 400 Slow hardener, which provides an extended working time (pot life) for assemblies that require precise positioning before curing.
Key Features
- High Gap Filling: Its thick, paste-like consistency allows application up to 30 mm thick at 15°C without sagging or slumping.
- Visual Cure Indicator: When mixed with the slow hardener, the cured adhesive turns a distinct green color.
- Mechanical Properties: Offers a high glass transition temperature (\(T_{g}\)), excellent toughness, low exotherm, and minimal shrinkage during cure.
- Mix Ratio: Easy to dose at a 3:1 ratio by volume.
- Compatibility: Its hardeners are fully shared and compatible with Spabond 435 and 440 systems.
- Certifications: It is Lloyd's Register approved and meets DNV standards.
