Curing behavior of melamine-urea-formaldehyde (MUF) resin adhesive

In this work, MUF resin was tested by DMA method. It showed that G′ curves and strain curves together could be used to predict the curing behavior of MUF resins. The study showed that sequential formulation was preferred for the preparation of MUF resins. Hardener could accelerate the curing of MUF resins. But its addition amount should not be too high to affect the resins' shelf time. MUF showed medium thermal resistance when compared with UF and MF resins.
