Spabond 540 Extra Slow Hardener is a curing agent designed by Gurit for its Spabond 540 modified epoxy adhesive system. This specific variant is formulated to provide the longest working time (pot-life) possible, making it ideal for bonding large-scale components in marine and industrial applications.Key Features
- Extended Working Time: Allows ample time for aligning, repositioning, and clamping large composite structures without the risk of premature curing.
- Low Exotherm and Shrinkage: Drastically reduces heat generation and shrinkage when filling thick bondlines.
- High Sag Resistance: Maintains excellent stability on vertical surfaces up to 30 mm thick without slumping.
- Visual Mix Indicator: The resin and hardener feature contrasting colors to easily confirm a completely homogeneous mix.
- High Toughness: Provides exceptional impact resistance and peel strength.
Common ApplicationsThis system is widely used in boatbuilding to bond critical structural components:
- Hull-to-deck joints.
- Bulkheads and stringers.
- Internal reinforcement framing.
