HydroGraph, a leading producer of ultra-pure graphene, and SEADAR Technologies, developers of the first subsea radar systems, have signed a letter of intent on September 19, 2025 to integrate HydroGraph’s graphene materials and coating technologies into SEADAR’s current and future undersea products.
The letter of intent describes how HydroGraph and SEADAR will collaborate to explore technical synergies that enhance performance for SEADAR products, positioning both companies to expand into new markets, such as maritime defense and offshore energy.
“Graphene is an extremely versatile and durable substance, and partnering with SEADAR allows us to develop new applications that can deliver real-world benefits,” said Kjirstin Breure, President and CEO of HydroGraph. “Our collaboration will lead to new corrosion-resistant coatings and graphene-enhanced compounds that will demonstrate how sustainable material innovation can have a lasting impact for marine applications and pave the way for new uses in other industries.”
Both companies plan to explore applications for HydroGraph graphene for various SEADAR applications and systems. For example, adding graphene to Kevlar-reinforced survey lines can increase tensile strength, reduce weight, and improve handling. Graphene coating can reduce corrosion and extend the life of SEADAR Shield node boxes and connectors. Graphene composites can make SEADAR structural components lighter and stronger, enabling them to handle mechanical loads and subsea pressures. Graphene can also improve thermal conductivity, dissipating heat to protect sensitive electronics.

“Our partnership with HydroGraph marks a significant step forward for our company,” said Carlos Fonts, CEO of SEADAR Technologies. “Incorporating HydroGraph’s graphene into SEADAR systems will not only improve the performance and durability of our products, but it will open the door for new advancements and applications of our technology.”
HydroGraph specializes in commercializing graphene production, supporting materials innovation for marine, aerospace, and industrial applications. The company has developed a controlled chamber explosion method to produce few-layered graphene at scale, cost-effectively. HydroGraph’s graphene products are engineered to perform in the harshest environments, reducing system weight, increasing strength, preventing corrosion, and enhancing energy efficiency. Graphene is also utilized in electronics for faster circuits and flexible screens, as well as in high-performance batteries, biomedicine, and drug delivery.
