Highlights
  • Two-part urethane delivers extremely tough, flexible bonds
  • Designed for vertical and other applications that require no slumping or sagging of the adhesive bead
  • Flexible adhesive that is capable of bonding dissimilar substrates
  • Non-Newtonian (Chemical reaction two-parts)

3M™ Scotch-Weld™ Urethane Adhesive DP640NS is a brown, non-sag, two-component polyurethane adhesive. This urethane adhesive has a 60 minute work life for panel bonding or repositioning. Ideal for bonding dissimilar substrates, such as composites, SMC, FRP, many plastics, ceramic, wood, rubber, and metal.

Compared to one part sealants, 3M™ Scotch-Weld™ Urethane Adhesive DP640NS is fast-curing, establishes tough bonds and offers low-temperature flexibility. It dispenses as a non-sag paste for accurate and precise handling during application. This adhesive can be used for bonding dissimilar substrates, such as concrete, ceramic, wood, plastic, rubber, and metal. With a 1:1 mix ratio, this urethane adhesive has a 60-minute work life, reaches handing strength in 8 hours and full cure in 7 days. Two part urethane adhesives cure chemically, rather than relying on moisture from the air. 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.

Suggested applications
  • Flexible plastic or composite bonding
  • 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
