Spabond 445 is a high-performance, toughened structural epoxy adhesive system manufactured by Gurit. It is specifically designed for bonding large structures and gap-filling on irregular surfaces. It serves as the direct replacement for the legacy Spabond 345 system.
Key Features
- Sag resistance: Thick, paste-like consistency allows vertical application up to 30 mm thick at 15°C without slumping.
- Mechanical properties: High Glass Transition Temperature (Tg), high toughness, and excellent resistance to fatigue and cyclic loading.
- Low shrinkage & exotherm: Minimizes residual stress in critical joints and reduces heat buildup during thick cures.
- Mix ratio: Simplified 3:1 ratio by volume using Spabond 400 series hardeners.
- Aesthetic options: Available in standard color or black version, ideal for cosmetic finishes on exposed carbon fiber parts.
