Epoxy resins, initially characterized by their robust mechanical properties and chemical resistance, undergo a series of alterations at the molecular level over extended periods. These modifications, driven by both internal factors related to the resin’s composition and external environmental influences, impact the material’s long-term performance. For example, a cured epoxy coating exposed to ultraviolet (UV) radiation may exhibit discoloration and a reduction in gloss due to degradation of the polymer chains.
Understanding the processes that influence an epoxy’s longevity is critical for applications ranging from aerospace engineering to civil infrastructure. Predicting and mitigating degradation contributes to enhanced structural integrity, extended service life, and reduced maintenance costs. Historically, advancements in polymer chemistry and materials science have steadily improved the durability and stability of epoxy formulations, leading to their widespread adoption across various industries.
