3M™ Plastic Bonding Adhesive
For reducing costs, streamlining assembly, and improving yield, 3M™ Plastic Bonding Adhesive 2665 is a product whose time has come. Based on hot-melt, moisture-curing adhesive technology, it delivers a long open time for easy assembly of parts requiring a thin bond line.
Features and benefits:
High tack holds parts together for immediate handling and fast production
4-minute open time allows initial repositioning even with thin bond lines that would otherwise cure too quickly for assembly
Low viscosity holds bead shape and size in small, defined areas
One-component eliminates potential inconsistencies of metering and mixing
100% solids provides a low-VOC system with no drying equipment and attack on plastics
Bonds and seals simultaneously
High performance for a wide range of consumer electronics because:
Tough flexible bond lines help improve fit, appearance, and reliability
High strength bonds plastics and metals, dissimilar substrates, and even hard-to-bond plastics such as polycarbonate
Improved appearance without the whitening from cyanoacrylate and cracking from ultrasonic welding
