OpticPB® 693 Series is a UV-cut optically clear adhesive (OCA) designed for outdoor displays and E-paper applications, enabling full lamination of touch display modules. The product provides excellent UV blocking capability, effectively reducing ultraviolet penetration into the display module and minimizing degradation of optical components caused by prolonged sunlight exposure.
It maintains high optical transparency and stable performance, allowing visible light transmission while blocking harmful UV radiation to preserve display quality. Suitable for outdoor touch displays and E-paper devices (e.g., reMarkable), the series is available in 100 μm and 250 μm thicknesses to meet various design requirements.
UV-Cut OCA OpticPB® 693 Series, designed for full lamination of outdoor touch displays and bonding of outdoor optical components.
Outdoor Touch Display Full Lamination — OpticPB® 69310 (250 µm)
Outdoor Optical Component Bonding — OpticPB® 6934 (100 µm)
