Belzona SF6-FIX is Belzona’s latest solution for the power transmission and distribution industry. Belzona SF6-FIX is a sulphur hexafluoride (SF₆) leak solution that can be applied online, and without specialist tools. This highly effective system can reduce SF₆ leaks in switchgear to undetectable levels.
Commonly used in electricity substations, SF₆ gas is used to insulate live electrical parts in medium and high voltage electrical equipment and to switch the flow of electrical current on and off. However, leaks of this gas are very common. With Belzona SF6-FIX, leaks can be quickly and expertly sealed resulting in huge environmental and financial savings. Solvent free and cold applied, Belzona safely seals SF₆ leaks and protects the environment, plus, this durable system of expertly applied specialist materials can be applied in just one day.


Award Winning SF₆ Leak Solution
Belzona SF6-FIX recently won the British Coatings Federation Sustainable Innovation Award.
"It’s an honour to receive the BCF Sustainable Innovation Award for Belzona SF6-FIX. SF₆ leaks are a significant contributor to global warming, so we set out to create a solution that could safely and reliably prevent these emissions while also supporting the sustainable and efficient operation of power grids. This award is a wonderful recognition of our efforts, and the whole team is absolutely thrilled."
- Karl Rodman, Key Developer of Belzona SF6-FIX
Belzona SF6-FIX has also been selected as a finalist for the prestigious Materials Performance Innovation Awards, run by the Association for Materials Protection and Performance
Key Benefits of Belzona SF6-FIX:
- Online application, minimum downtime
- Rapid installation, short cure times
- Can reduce leaks to undetectable levels
- Removable for joint access

Why is Stopping SF₆ Leaks So Important?
Despite its utility, SF₆ is incredibly detrimental to the planet. With a warming potential 23,500 times higher than carbon dioxide (CO₂), SF₆ is the most potent greenhouse gas (Intergovernmental Panel on Climate Change, fifth assesment report). This means that even in minute quantities, SF₆ has a disproportionately significant impact on global warming. Worryingly, the Environmental Protection Agency notes that leak detection surveys show approximately 10 percent of circuit breaker populations leak and, 85% of these leaks are releasing enough of this dangerous gas to be considered significant. Frequent leaks of such a potent greenhouse gas have become a serious contributing factor to global warming. Belzona SF6-FIX offers an effective, long-term solution which not only tackles the environmental concerns associated with SF6 emissions but also promotes the sustainable and efficient operation of power grids.
