Royalton Coating Systems has announced a collaboration with PETRONAS Technology Ventures (PTVSB), the technology commercialization arm of Petroliam Nasional Berhad (PETRONAS), to validate a graphene-enhanced underwater epoxy coating aimed at improving corrosion protection in marine and industrial environments.
The partnership focuses on upgrading Royalton’s ROYALPOXY UW 410 underwater epoxy system with ProShield+™, a graphene-based additive developed by PETRONAS. The enhanced coating is currently undergoing evaluation for use in harsh conditions, including offshore platforms, pipelines, jetty structures, and marine vessels - applications where continuous exposure to seawater, humidity, and chemicals significantly accelerates material degradation.
According to Royalton, incorporating graphene into the coating formulation is expected to significantly enhance barrier performance by limiting the ingress of water, oxygen, and salts. In addition, the company anticipates improvements in mechanical durability, adhesion, and resistance to micro-cracking, particularly under prolonged immersion conditions.
ROYALPOXY UW 410 is specifically engineered for application on wet, oily, and fully submerged surfaces. This capability allows maintenance and repair work to be conducted without removing infrastructure from service in certain cases, helping operators reduce downtime and associated costs in offshore and marine environments.
Beyond marine use, the companies are also assessing the coating system’s potential in broader industrial and infrastructure applications where corrosion control and maintenance efficiency are critical.
The collaboration is also aligned with efforts to strengthen Malaysia’s industrial innovation ecosystem, particularly in sectors related to energy infrastructure, ports, and heavy industry.
PETRONAS has been known to work with Haydale on various graphene-enhanced commercial applications.
