3M Optically Clear Adhesive 8146-x

Product Description

The 3M™ Optically Clear Adhesive 8146-x represents a significant advancement in pressure-sensitive adhesive technology. This innovative adhesive offers crystal clear, high-reliability optical coupling for a diverse range of transparent materials. Furthermore, it provides robust mechanical joining capabilities, ensuring the integrity and performance of your assemblies.

The 3M™ Optically Clear Adhesive 8146-x is engineered for exceptional long-term durability. It resists yellowing, delaminating, and degradation even under challenging conditions. Consequently, it maintains high light transmission, exceeding 99% when corrected for reflection losses. This ensures the ultimate visual clarity for your optical components.

This adhesive is free of birefringence, a common issue with film carriers, as it uses no film carrier itself. It exhibits high temperature, humidity, and UV resistance. These properties are crucial for devices exposed to varying environmental conditions. The adhesive also provides high cohesive and peel strength, reliably bonding most transparent substrates.

This versatile adhesive is also suitable for bonding a variety of other high surface energy substrates, including glass and PET, as well as some lower surface energy materials. Therefore, its application scope is broad, extending to transparent graphic overlays, projection screens, and advanced avionics/military displays. It is also perfect for optical management films in LCDs.
