Modified bitumen-polymer mastic to protect metal coatings from corrosion

Abstract

The protection of metallic structures against corrosion remains a pivotal challenge across numerous industries. In recent years, the amalgamation of modified bitumen with epoxy resin has emerged as a promising avenue in the pursuit of enhanced corrosion protection. This novel composite material showcases exceptional potential in thwarting the deleterious effects of corrosion, offering an innovative solution to safeguard vital infrastructure, industrial components, and diverse metallic substrates. The synergistic properties stemming from the combination of modified bitumen and epoxy resin present an intriguing prospect for superior durability, chemical resistance, and structural integrity, thereby fostering advancements in the realm of anti-corrosion coatings. This scientific article endeavours to explore the efficacy, mechanisms, and potential applications of this composite material as an effective barrier against corrosion, shedding light on its transformative impact within corrosion mitigation strategies. In this study, bitumen was modified using epoxy resin ELM-NG900Z and hardener in a ratio of 1.0: 5: 1.5 respectively. The modified bitumen was further tested by mechanical tests and solvent tests. The samples of modified bitumen successfully passed the tests and showed results better than the reference(epoxy resin without bitumen).
