Both the transparency and the yellowness index of the cured materials are significant impact factors for LED filament bulb package.The materials cured by various curing agents exhibited fairly high transparency as shown by Fig.6.The yellowness index(Table 2)for the material cured by PEA-230 was the lowest,which indicated that the anti UV ability of the material was the best.The tensile shear test for the cured materials obtained by various curing agents is summarized in Table 3.As can be seen,the cured materials had good adhesive ability.
