Details
This grey sandable structural adhesive delivers outstanding versatility and performance across a range of demanding applications. It bonds materials securely and sands easily once cured, making it ideal for achieving a smooth, refined finish. Its dense, high-performance formula fills voids and gaps effectively, restoring surface integrity and creating strong, reliable bonds. You can also use it as a fairing compound to shape and smooth uneven surfaces before painting or coating. The non-sag consistency keeps it in place after application, even on vertical or overhead surfaces. Whether you’re bonding, filling, or fairing, this adhesive handles all three tasks with consistent, dependable results
Storage stability
This product should be stored indoors in a dry environment at temperatures between 60–80°F (16–27°C) to maintain performance and extend shelf life. When kept in its original, unopened containers and stored correctly, it has a standard shelf life of six months from the date of shipment from 3M. However, Part A (Accelerator) and Part B (Base) are moisture-sensitive and can absorb humidity from the atmosphere, which may affect performance. Always keep containers tightly sealed, as this helps prevent skin formation and ensures strong, non-porous bond lines during application.
