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.

Key Features

1. Mechanical Strength: Epoxy polyester resins exhibit excellent mechanical properties. For example, adding polyester enhances the impact strength significantly compared to pure epoxy, which can increase impact strength by over 250% and fracture strength by 127% when modified appropriately (Luo et al., 2011).

2. Thermal Stability: The thermal stability of epoxy polyester blends is enhanced by polyester. For instance, blends with polyester show improved thermal conductivity, specific heat capacity, and a slight reduction in glass transition temperature. The decomposition temperature of these resins can improve by about 20°C with the proper addition of polyester (Ali et al., 2021).

3. Processing Ease: One of the significant advantages of epoxy polyester resins is their ability to be processed easily at ambient temperature with a low viscosity and easy molding properties, making them suitable for diverse applications in coating and composite materials.

4. Environmental Resistance: These resins show excellent resistance to water, chemical corrosion, and UV degradation, making them ideal for use in harsh environments. The blend of polyester in epoxy helps improve chemical resistance, a feature critical for applications like automotive and construction materials (Torrón et al., 2016).

5. Adhesion: Epoxy resins provide superior adhesion to various substrates, including metals, plastics, and glass, while polyester increases the resin's ability to adhere to fibrous materials (Oliveira et al., 2019).
