Developing acrylated soybean oil-based UV-curable coatings
The combination of biomass and UV curing technology can reduce the dependence on petroleum products and VOC emissions. In an article, a new environment-friendly UV-curable coating with good performance was prepared from acrylated soybean oil.
Acrylated soybean oil (ACSO) was obtained at low temperature without catalyst and inhibitor by reacting soybean oil-based polyol with acryloyl chloride and characterised by Fourier transform infrared spectroscopy and nuclear magnetic resonance.
Better adhesion and impact resistance
It was found that the UV-curable oligomer of ACSO had lower viscosity and better ductility, compared to acrylated epoxidised soybean oil (AESO). The properties of UV-cured films prepared by ACSO were studied and compared with films from AESO. The results showed that the ACSO-based films were significantly improved in the adhesion and impact resistance. Furthermore, the addition of styrene could enhance the hardness and impact resistance of films.
