In this study, the effects of four single-component curing agents on the basic properties of UF resins were investigated. The basic properties include pH, gel time and valid period. The studies have shown that different curing agent types and additions have different effects on the basic properties of urea-formaldehyde resins. The degree of influence of different curing agents of the same addition amounts: APS>AC>AS>AP, the degree of influence of different addition amounts of the same curing agent: 5%>2%>1%. Comprehensive comparison of four single-component curing agents, the optimal curing agent is AC, the optimal addition amount is 2%. This study laid the foundation for the subsequent study of the effects of multi-component curing agents on the properties of resins.
