Curing Reaction and Physical Properties of Acrylic High-Solid Coatings

An ACR/HMMM film was prepared by blending high-solid ACR with curing agent, hexamethoxymethyl melamine (HMMM). An active curing reaction was observed at 170℃. The dynamic viscoelastic Tg of the final film increased with the static viscoelastic Tg of the film. The log damp value, which means a viscoelastic ratio, decreased with the increase in the curing temperature of the film. Physical properties of the films were within a suitable range for films, and by an accelerated weathering resistance test the films were proved weather resistible ones.
