Abstract: Properties of cured product and affecting factors of the reaction were researched using allyl resinate as monomer. Conversion rate of vinylic double bonds was characterized and detected by FT-IR analysis and mechanical properties of cured films were detected. Results showed that conversion of double bonds first increased and then decreased with the increase of the dosage of initiators, and increased with the increase of irradiation time. Surface drying time became shorter, that is, relative curing speed became faster with the increases of dosage of initiator and irradiation intensity, and the decrease of lamp distance. At lamp distance 4.5cm and irradiation intensity 100%, conversion rate of vinylic double bonds was 97.9% using irradiation time 250s with 8% of MK, while conversion rate was 97.6% using irradiation time 300s with 5% of Darocure 1173 as photoinitiator. The obtained UV-cured coating possessed superior properties in flexibility, impact strength and adhesion, as well as good properties in hardness, acid resistance, alkali resistance, salt resistance and water resistance.
