UV cure optical display adhesives offer crystal clear bonds

This new Dymax family of Ultra Light-Weld optical display and touch screen adhesives are available in varying viscosities for use in flat panel display bonding where bond strength, non-yellowing, and re-workability characteristics are important. The two low-viscosity materials, 9701 and 9702, offer easy-flow characteristics for panel laminations while 9703, the higher viscosity product, is available for damming requirements.

Intertronics advise that these adhesives feature "on-demand cur" with UV/visible light which means that substrates can be repositioned precisely until parts are ready to be cured, while using a thin layer of adhesive controls cost and can reduce the weight of the final product. LCD adhesives help reduce air entrapment and bubbles to create strong, ripple-free bonds that help increase panel strength - they also act as a barrier against stress, significantly improving product reliability and warranty costs. Ultra Light-Weld adhesives are suitable for bonding - glass/glass, PET/ITO glass, CAB polariser/acrylic, polycarbonate/polycarbonate, glass or polycarbonate/CTA, polycarbonate/mesh/polycarbonate.

Other characteristics include: non-yellowing for increased light transmission, enhanced brightness, optical clarity, and better contrast ratios; excellent bond strength; superior re-workability for easy removal or repair; easy flow characteristics for flat panel lamination; excellent thermal shock resistance; and low shrinkage which minimises visible distortion after cure.
