Product Introduction
3M™ Scotch-Weld™ Urethane Adhesive EC-3587 B/A is a two-part urethane adhesive that creates tough, impact-resistant bonds on a wide variety of primed or painted metal and plastic substrates. Formulated to resist sagging within 30 seconds of mixing, it ensures clean and accurate application, even on vertical surfaces. This adhesive offers process flexibility by curing at room temperature or with accelerated heat. It is available in two versions to suit different production needs: EC-3587 B/A B-1/4 provides a 20-minute work life for faster assembly, while EC-3587 B-1 offers a 60-minute work life for applications requiring more time for positioning and adjustment. Both versions deliver high peel strength and long-term durability.
3M™ EC-3587 B/A Features:
- High Peel Strength: Provides strong, durable bonds for long-term reliability.
- Impact Resistant: Formulated to withstand shock and impact, creating tough structural bonds.
- Sag Resistant: Enables accurate, drip-free application on vertical or overhead surfaces.
- Variable Work Life: Available in a 20-minute (B-1/4) or 60-minute (B-1) work life for process flexibility.
- Flexible Curing: Cures effectively at room temperature or with heat to speed up production.
- Excellent Adhesion: Bonds well to many primed or painted metals and plastics.
3M™ EC-3587 B/A Applications:
- Bonding primed or painted metal components in automotive and industrial assemblies.
- Structural bonding of plastic parts.
- Applications requiring high peel strength and superior impact resistance.
- Situations demanding non-sag adhesives for vertical or precision applications.
- Projects that benefit from adjustable work life and room-temperature curing options.
