Overview
Engineered for bonding metals, composites, and plastics—including dissimilar materials—SG350L delivers strength and flexibility in the most demanding environments.
- With an advantageous balance between open time and fixture time compared to other methyl methacrylate systems, it ensures efficient application without compromising performance.
- SG350L remains stable without boiling even at large bond gaps up to 150mm, making it ideal for repair or backfill of large composite structures across transportation and marine applications.
- SG350L is DNV GL approved for wind blade applications, giving manufacturers confidence in its performance for structural bonding within the wind energy sector.
