Abstract: A series of UV curable acrylate resins(UV-WZF) has been prepared by the addition of methyl methacrylate(MMA), butyl acrylate(n-BA), tri(propylene glycol) diacrylate(TPGDA), 3-glycidoxypropyltrimethoxysilane(KH570), 1-dodecanethiol(NDM) as a chain transfer agent, 2,2′-azobis(2-methylpropionitrile) as an initiator. The structure and property of the UV-WZF oligomer was characterized using infrared spectroscopy (FT-IR), DSC and TG. In addition, the effects of KH-570 and TPGDA dosage on the adhesion and curing rate of the film are investigated. The results shown that the adhesion is optimal when the KH-570 dosage is 6％ and the curing time is the shortest when the TPGDA dosage is 26％. The UV-curing kinetics of the UV-WZF oligomer are also investigated by real time FT-IR.When the amount of photoinitiator Darocur1173 is 5％, the UV-curing rate of the UV-WZF oligomer is optimal. The increased light intensity of the radiation can improve the UV-curing rate of the system
