Prestone Products, a US-based supplier of coolants and corrosion protection fluids, has introduced three new low-conductivity, corrosion-protectant thermal management fluids to meet upcoming industry specifications for EV coolants. These products include a new silicate organic inhibitor technology EV thermal management fluid that meets standards such as the EV coolant-specific GB29743.2 standard, which aims to enhance safety by providing enhanced reserve alkalinity to extend EV lifespans. Additionally, Prestone has launched a low-conductivity phosphate organic acid technology EV thermal management fluid that also meets the GB29743.2 standard and provides corrosion protection and compatibility with flux-brazed aluminum without containing silicate, borate, or amine.
In addition to these products, Prestone has introduced an ultra-low conductivity fuel cell coolant designed for compatibility with PEM fuel cell stacks, as hydrogen fuel cells have distinct requirements that necessitate ultra-low electrical conductivity for cooling fluid. This formulation was developed from the ground up using high-purity and non-ionic corrosion inhibitors. With the increasing focus on EVs globally, vehicle OEMs operating or selling vehicles in China will need to comply with the GB29743.2 standard by mid-2026, which mandates a significant reduction in the electrical conductivity of coolants to enhance battery safety. It is expected that this standard will eventually apply to the global industry as a whole.
Matt Kern, the Senior Director of Global Sales at Prestone, highlighted the importance of combating corrosion in automotive components, especially in the highly sensitive systems of electrified vehicles. Prestone’s thermal management fluids are designed to serve as an ally in preventing corrosion and forming a protective barrier to shield these systems from the detrimental effects of corrosion. By developing these advanced fluids, Prestone aims to contribute to the longevity and reliability of automotive components, ultimately benefiting the overall performance and safety of EVs. These new products reflect Prestone’s commitment to innovation and meeting the evolving needs of the automotive industry as it transitions towards electrification.
The introduction of these new thermal management fluids by Prestone addresses the growing demand for high-performance coolants and corrosion protection solutions in the EV market. As electric vehicles become increasingly popular worldwide, there is a growing need for specialized fluids that can effectively protect sensitive components and ensure optimal performance. By meeting industry specifications and standards such as the GB29743.2 standard, Prestone’s products are positioned to help OEMs comply with regulations and enhance the safety and reliability of EV systems. With these innovative offerings, Prestone aims to establish itself as a leading provider of thermal management solutions for the automotive industry, particularly in the rapidly expanding EV sector.
Overall, Prestone’s latest developments in thermal management fluids demonstrate a proactive response to the changing landscape of the automotive industry, driven by the shift towards electric vehicles. By introducing advanced products that address specific requirements for EV coolants and fuel cell cooling, Prestone is well-positioned to support vehicle manufacturers in meeting stringent standards and regulations. As the industry continues to evolve, the demand for specialized thermal management solutions will only increase, and Prestone’s commitment to innovation and quality positions them as a key player in the growing market for EV fluids and corrosion protection products.
