3M Scotch-Weld™ Structural Adhesives Primer EC-1945 B/A for Metal & Composite Bonding | Two-Part High-Performance Primer

3M Scotch-Weld Structural Adhesives Primer EC-1945 B/A is a two-part, chemically curing primer system (Base + Accelerator) designed to enhance adhesion and corrosion resistance in structural bonding applications. It is widely used in aerospace and high-performance industrial assembly, where strong, durable bonding between metal substrates and structural adhesives is critical. This primer improves the performance of epoxy and polyurethane adhesives, while also protecting bonded surfaces from corrosion over time.

Features:

- Base + Accelerator ensures strong, stable primer layer.
- Designed for aluminum, steel, and other metal substrates.
- Protects both inside and outside the bond line.
- Eliminates need for additional heating process.
- Suitable for complex or large-area processes.

Applications:

Aerospace structural bonding, Aircraft components and assemblies, Metal-to-metal bonding systems, Epoxy & polyurethane adhesive systems, Anti-corrosion coating for metal parts.
