Abstract

Hermetic sealing of a display cell containing a highly corrosive liquid, such as heptyl viologen, has proved difficult. The cell consists of a glass base 1 and a transparent plastic cover 2. These are conventionally bonded with an ethyl-cyanoacrylate instant adhesive 3. A fillet 4 of high viscosity modified methylacrylate ester is laid around the perimeter of the cell and is partially cured by ultraviolet irradiation at 365 nm. The resultant, highly tacky substance provides the hermetic seal. The seal is encapsulated in a liquid plastic 5.
