Details

3M™ Scotch-Weld™ Urethane Adhesive DP604NS is a black, non-sag, two-component polyurethane adhesive. Rapid-setting, this urethane adhesive offers a fast, very flexible solution that can be used for bonding dissimilar substrates, such as concrete, ceramic, wood, plastic, rubber, and metal.

As a non-sag, two-component polyurethane adhesive, 3M™ Scotch-Weld™ Urethane Adhesive DP604NS is fast-curing. This adhesive quickly establishes tough bonds and offers low-temperature flexibility. 3M™ Scotch-Weld™ Urethane Adhesive DP604NS 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 4-minute work life, reaches handing strength in 20 minutes and full cure in 6 hours. 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, 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

  • Bonding wood, metal, or composite door frames to wood or other surfaces
  • Staking electronic components
  • Covering material against corrosion
  • Sealing fabric water hoses
  • Encapsulating for tamper proofing
