3M 7100148761 | Scotch-Weld 640 1.64 fl oz Brown Urethane Adhesive

3M Scotch-Weld Urethane Adhesive DP640NS is a brown, non-sag, two-component polyurethane adhesive. This urethane adhesive has a 60 minute work life for panel bonding or repositioning. Ideal for bonding dissimilar substrates, such as composites, SMC, FRP, many plastics, ceramic, wood, rubber and metal.

When using a Duo-Pak (DP) size adhesive, rely on 3M dispensing equipment for convenient and accurate metering, mixing and dispensing.

As compared to one part sealants, 3M Scotch-Weld Urethane Adhesive DP640NS 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.

• Flexible plastic or composite bonding
• Bonding composite panels to frames for transportation applications
• Bonding wood, metal or composite door frames to wood or other surfaces
• Bonding wood paneling to wood or plaster
• Understanding Urethane Adhesives

Two part urethane adhesives cure chemically, rather than relying on moisture from the air. Because of this, they can cure quickly with no depth of cure issues in contrast to one-part urethane adhesive sealants. Urethane adhesives will bond most common materials such as wood, metals, rubbers, leather, tile and 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.

Features:

• Two part urethane delivers extremely tough, flexible bonds
• Designed for vertical and other applications that require no slumping or sagging of the adhesive bead
• Low-temperature flexibility
• Flexible adhesive that is capable of bonding dissimilar substrates
• Non-Newtonian: (Chemical reaction two-parts)
• Brown color
