To find an easy way to study a curing process for urea-formaldehyde resin,the authors made use of time-domain nuclear magnetic resonance(TD-NMR)to evaluate the process with zinc chloride as the curing agent.The results showed that relaxation time distribution for ureaformaldehyde resin in the solidification process was rapidly formed.The curing reaction of the UF resin occurred as the temperature rose from 100℃to 120℃,and was completed at 140℃.
