3M™ Scotch-Weld™ DP6330NS Multi-Material Urethane Adhesive

The 3M™ Scotch-Weld™ DP6330NS Multi-Material Urethane Adhesive is a green, non-sag, two-part urethane paste system designed to bond a variety of composites, plastics, metals, and wood. This flexible adhesive features excellent elongation and stress-handling properties for durable bonding of composite parts and assemblies involving different materials.

When using a Duo-Pak (DP) sized adhesive, rely on the 3M dispensing equipment for convenient and precise dosing, mixing, and application.

Features:

• Bonds most composites and different substrates
• Specifically designed for composite and multi-material assemblies, the 3M™ Scotch-Weld™ DP6330NS Urethane Adhesive delivers outstanding strength and performance.
• With excellent elongation and stress resistance properties, it ensures durable bonding of composite parts and multi-material assemblies, including plastics, metals, and wood.
• It has a 1:1 mix ratio, a 30-minute open time, and reaches handling strength in approximately 2 hours.
• This green adhesive offers excellent water and moisture resistance, along with very good chemical resistance.

Recommended Applications:

• Bonding composite or plastic panels to metal frames
• Bonding composites to each other

The 3M™ Scotch-Weld™ DP6330NS Multi-Material Urethane Adhesive can replace rivets and screws in bonding composites to other substrates, providing a more aesthetic and fatigue-resistant bond line. It also bonds well to most metals without the need for priming.

What Are Urethane Adhesives?
Two-part urethane adhesives cure chemically rather than relying on air moisture. As a result, they cure quickly without depth-of-cure issues, unlike one-part urethane adhesive sealants. Urethane adhesives bond most common materials such as wood, metals, rubber, leather, tiles, glass, various plastics, concrete, and more.

The versatility of urethane adhesives is evident in their different formulations, offering varied curing properties such as levels of stiffness or flexibility, open times, curing speeds, and hardness. They can cure to a relatively rigid or highly flexible state to meet a wide range of requirements. In either state, urethane adhesives maintain bond strength integrity despite variable environmental factors such as temperature, humidity, and chemical exposure.
