Product Introduction
3M™ Scotch-Weld™ Urethane Adhesive 3549 is a brown, non-sag, two-component polyurethane adhesive designed to create tough, flexible bonds. It is particularly effective for bonding dissimilar substrates such as composites, SMC, FRP, plastics, wood, and metal. With a generous 60-minute work life, there is ample time for positioning parts. This fast-curing adhesive forms a non-sag paste upon mixing, allowing for precise application on vertical surfaces without dripping. As a two-part urethane, it cures chemically, ensuring a quick and deep cure that provides excellent low-temperature flexibility and long-term durability.
3M™ 3549 Features
- Tough, Flexible Bonds: Two-part urethane formula delivers extremely durable and flexible bonds.
- Non-Sag Formula: Ideal for vertical applications, as the adhesive bead will not slump or sag.
- Low-Temperature Flexibility: Maintains bond integrity even in cold environments.
- Bonds Dissimilar Substrates: Effectively joins a wide range of materials, including composites, plastics, wood, and metal.
- 60-Minute Work Life: Provides ample time for panel bonding and repositioning.
3M™ 3549 Applications
- Bonding flexible plastics or composites.
- Attaching composite panels to frames in transportation applications.
- Bonding wood or metal door frames to various surfaces.
- Securing wood paneling to wood or plaster.
- General industrial applications that require a strong, flexible, and non-sag adhesive.
