About 3M DP620NS Black Urethane Adhesive

3M DP620NS 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, plastics, rubbers, ceramics, and glass (may require primer for durability).

Flexible Adhesive That Delivers Tough Bonds

Compared to one-part sealants, 3M Scotch-Weld Urethane Adhesive DP620NS 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 and can be used for bonding many dissimilar substrates. With a 1:1 mix ratio, this urethane adhesive has a 20-minute work life, reaches handling strength in 4 hours, and fully cures in 48 hours.
