Abstract
Disclosed is a sealant composition. The sealant composition is composed of an epoxy resin having an active group, α-cyanoacrylate, an initiator wrapped with an inert sheathing material, a thermal curing agent, a filler, a coupling agent and an epoxy resin having no active groups. In the invention, a method for initiating sealant curing via a chemical initiator is employed, thus the UV irradiation process may be avoided, the cell alignment process may be simplified, and the cost of UV process and UV Mask, etc., may be saved; additionally, the sealant cure effect is uniform and controllable, and the risk of sealant break and liquid crystal pollution may be avoided.
