3M™ Scotch-Weld™ Urethane Adhesive 620NS is a flexible, two-part polyurethane based structural adhesive that performs well in numerous applications where some flexibility is needed. It effectively bonds to many substrates such as composites, metals, wood, and many plastics and rubbers, ceramics and glass (may require primer for durability).
- Bonding composite panels to frames for transportation applications
- Bonding wood, metal or composite door frames to wood or other surfaces
- Bonding wood paneling to wood or plaster
- Sealing fabric water hoses
- Encapsulating for tamper proofing
- Flexible plastic or composite bonding
Two part urethane adhesives (PDF, 1.36 Mb) cure chemically, rather than relying on moisture from the air. Because of this, they can cure quickly with no depth of cure issues in contrast to one-part urethane adhesive sealants. Urethane adhesives will bond most common materials such as wood, metals, rubbers, leather, tile and glass, many plastics, concrete and more.
The versatility of urethane adhesives is exhibited in the different formulations that have varying cured properties such as different levels of stiffness or flexibility, open time and cure speed, and hardness. They can cure to a relatively rigid or highly flexible state to meet a wide range of requirements. In either finished state, urethane adhesives will maintain bond strength integrity through variable environmental factors such as temperature, moisture and chemical exposure.
