3M Scotch-Weld DP-6310NS

This product is a high-strength bonder with some flexibility to accommodate thermal expansion and contraction differences when bonding dissimilar materials. It bonds most composites and a wide range of metals without the need for priming, and its non-sag formulation resists running or slumping for precise application. Curing occurs at room temperature, with the option to accelerate the process using heat. It can replace rivets and screws for attaching composites to other substrates, creating a more aesthetically pleasing, fatigue-resistant bond line.

Designed for durable bonding of composite parts and multi-material assemblies, this flexible adhesive offers excellent energy absorption, elongation, and stress-strain properties. Supplied as a green, 1:1 mix ratio system, it provides a 10-minute open time and reaches handling strength in approximately 45 minutes, making it ideal for assemblies where adjustment and precise positioning are required.
