Abstract
Disclosed is a sealant composition, a liquid crystal device and a method for preventing liquid crystal contamination using the sealant composition. The sealant composition consists of 20-30 parts by weight of an ultraviolet polymerizable double bond monomer, 15-20 parts by weight of a heat polymerization monomer, 5-20 parts by weight of a polymerizable oligomer, 0.1-5 parts by weight of a photoinitiator, 10-20 parts by weight of a heat curing agent and 0-20 parts by weight of a particulate additive, wherein said polymerizable oligomer is poly(ethylene glycol) diacrylate or derivatives thereof. Through the reaction between the polymerizable oligomers and the polymer of the ultraviolet polymerizable double bond monomers to generate a reticular high molecular polymer, the anchoring effect of the polymer on the surrounding unreacted heat polymerization monomers is effectively enhanced, thereby reducing the contamination of the crystal liquid by the sealant.
