Product Introduction
3M™ Scotch-Weld™ Epoxy Adhesive EC-3537-NA B/A is a two-part, thixotropic epoxy formulated to create tough, highly flexible bonds. Designed to meet demanding aerospace requirements, this off-white adhesive excels at bonding metal and plastic substrates. It offers a versatile cure profile, curing at room temperature in 3-7 days or in less than an hour at 200°F. Its non-sag formula holds its shape, permitting clean application on both vertical and horizontal surfaces. For quality control, the two parts feature contrasting gray and white colors, providing a clear visual confirmation that the adhesive has been thoroughly mixed.
3M™ EC-3537-NA B/A Features
- Highly Flexible: Creates a tough, flexible bond that improves service life and reduces damage from vibration or impact.
- Versatile Cure: Cures at room temperature (75°F) or can be accelerated with mild heat (under 1 hour at 200°F).
- Non-Sag Formula: Thixotropic consistency holds its shape for precise application on vertical surfaces.
- Visual Mix Indicator: Contrasting gray and white parts turn to a uniform off-white color when properly mixed.
- Aerospace Performance: Designed for high-performance bonding of metal and plastic substrates.
3M™ EC-3537-NA B/A Applications
- Aerospace bonding where high flexibility and strength are required.
- Bonding metal to plastic in industrial assemblies.
- Applications on vertical or overhead surfaces where sag resistance is critical.
- Structural bonding that requires a tough, durable, and damage-resistant epoxy.
