Biodegradable lignin as a reactive raw material in UV curable systems

ABSTRACT

Radiation curing technologies, including ultraviolet (UV) and electron beam curing, have received increasing attention especially after the increasing concerns on energy consumption, environmental protection, and occupational health and safety. Ultraviolet (UV)-curable polymerization are progressively being utilized in numerous manufacturing since they can be speedily applied in addition to their outstanding physical properties such as excellent surface quality, productivity, and slow energy consuming.This paper briefly reviews the research milestones in the area of wood chemical modification, focusing on the basic principles and applications of UV curable systems and polymerization. The study also extends to highlight the effect of lignin incorporation into UV curable system on coating quality, thermal stability, chemical resistance and mechanical properties.
