Abstract:

The factors of the UV curing reaction were investigated using isopimaric acid as monomer. Conversion rate of double bond was characterized and detected by FT-IR analysis. And the obtained UV-cured coating was characterized by gel permeation chromatography (GPC), differential scanning calorimetry (DSC), and thermogravimetric analysis (TG), respectively. The results showed that the conversion of double bonds increased at primary stage and then decreased with the increment of the dosage of initiators meanwhile increased with the increment of irradiation time. Relative cured speed increased with the dosage of initiator, irradiation intensity, and the decreasing lamp distance.

Key words: Iso-pimaric acid, UV curing, Conversion rate of double bonds, Performance
