The acrylated epoxy resins are the acrylated epoxy resins of resorcinolformaldehyde resin.
The viscosity of the thermal curing agents is 100-170Pas at 25 DEG C.
The organic filler is selected from polymethyl methacrylate, polystyrene, methyl methacrylate and other monomers
It is one or more of in copolymer, the copolymer of styrene and other monomers, polyester micropartical, polyurethane grain and rubber particle
Mixture.
The light trigger, which is preferable over, can form the light trigger of free radical, include benzoin based compound, acetophenones
Compound, benzophenone compound, thioxanthene ketone class compound, α-acyl group oxime ester compound, benzoin class compound, benzene are even
Relation by marriage ether compound, benzoyl formic acid esters compound, benzil class compound, Azo, green onion quinones.
Compared with prior art, the beneficial effects of the invention are as follows：Sealant produced by the present invention not only can be to display surface
Plate carries out the stable accurate coating of sealed width, and when being positioned over 25 DEG C sealant viscosity B coefficent it is also small；Can by with
Liquid crystal pollution when light irradiation is carried out in the state of liquid crystal contact suppresses in Min., and in reliability test, heat
The sealing of the display panel completed after solidification will not also be peeled off occur liquid crystal leakage.
