The use of natural rubber-based material for the preparation of radiation -curable resin. II. Formulation and ultra-violet (UV) curing of low molecular weight epoxidised natural rubber acrylate (ENRA) - some basic studies
[en] The UV curing of newly developed acrylate resin based on natural rubber has been investigated. Two types of reactive diluent i.e.tripropylene glycol diacrylate (TPGDA) and trimethylol propane triacrylate (TMPTA), together with photoinitiators such as benzophenone, 1-benzoylcyclohexanol and N-methyl diethanol amine were used. Curing was done on a 20 cm width IST Minicure 200 UV curing machine. The curing properties were monitored by cure rate, gel fraction, pendulum hardness and chemical resistance measurements
