Product Description

3M™ Scotch-Weld™ Urethane Adhesive DP604NS Black is a rapid-setting, two-component polyurethane adhesive supplied in a 1:1 ratio duo-pak cartridge. The EPX™ dispensing system mixes the components into a bubble-free, non-sag black paste for structural bonding and sealing. The mixed adhesive provides a 4-minute open time and reaches set strength in approximately 20 minutes at 23 °C. After cure, it combines 85 Shore A hardness with 420% strain at break and a continuous temperature range of -51 to 121 °C. Applications include manufacturing and assembly, building maintenance and repair, bonding door frames and sills, and general structural bonding and sealing.

Key features

  • Rapid-setting formulation: Provides a 4-minute open time and approximately 20-minute set time at 23 °C.
  • Controlled 1:1 dispensing: Duo-pak packaging supports automatic component mixing and bubble-free application through the 3M™ EPX™ system.
  • Flexible cured performance: Delivers 420% strain at break, 85 Shore A hardness, and a continuous temperature range of -51 to 121 °C.

Applications / Suitable for

  • Manufacturing and assembly
  • Building and construction maintenance and repair
  • Bonding wood or metal door sills to concrete
  • Bonding wood and metal door frames to supporting structures
  • General structural bonding and sealing
