3M™ Optically Clear Adhesive 826x
3M™ Optically Clear Adhesive 826x is bare ITO compatible and outgassing resistant. It is commonly used in touch screen displays and other applications requiring an optically clear bond.
Features and Benefits
High interfacial adhesion
Non-whitening at high temperature/humidity
Enhanced durability on outgassing substrates (PC, PMMA)
Bare ITO compatible for touch applications
High temperature, humidity, and UV resistance
Long term durability without yellowing, delaminating, or degrading
High cohesive and peel strength for reliably bonding most transparent substrates
Wound on plastic cores and wrapped in plastic to eliminate paper fiber contamination
Two film liners for optimum adhesive smoothness and differential release for ease of processing and protection from contamination.
3M™ Optically Clear Adhesives (OCA) are highly specialized optically clear free-film adhesives offering superior clarity and excellent adhesion to various types of transparent substrates. 3M OCAs are easy to convert and are contaminant-free, resulting in improved bubble resistance in lamination exposed to high temperature and high humidity. Common application example is display bonding. Available in the following product numbers: 8261, 8262, 8263, 8264 and 8265.
