polyesterharts
Polyesterharts are a class of thermosetting polymers formed by crosslinking polyester resins with reactive hardeners to create rigid three‑dimensional networks. They are commonly referred to as polyester hard resins and are valued for their combination of chemical resistance, mechanical stiffness, and heat tolerance.
Chemistry and synthesis aspects commonly involve unsaturated polyesters derived from diols and dibasic acids, such as
Properties of polyesterharts typically include high modulus and good chemical and weathering resistance, along with the
Processing and applications encompass coatings, fiber‑reinforced composites, automotive refinishes, marine coatings, and construction laminates. Polyesterharts are
Safety and environmental considerations include handling of solvent‑borne formulations to control volatile organic compounds, proper ventilation,
