This is the greatest advantage of unsaturated polyester resin. It can cure at room temperature and form under normal pressure, with flexible process performance, especially suitable for large-scale and on-site manufacturing of fiberglass products. After curing, the resin has good comprehensive properties, with mechanical performance indicators slightly lower than those of epoxy resin but superior to phenolic resin. Corrosion resistance, electrical properties, and flame retardancy can be met by selecting appropriate grades of resin. The resin has a light color and can be made into transparent products.
