Which type of fiberglass storage tank has better corrosion resistance when storing hypochlorous acid? Bonus points for participants!
Additional conditions: temperature below 60 degrees, concentration below 5%.
It’s best not to use it; generally, this isn’t necessary. You can try using PP containers instead

Phenolic, epoxy, and furan fiberglass are prone to corrosion; polyester resin fiberglass can be used instead.
Phenolic resin is not good; polyester resin seems to be a bit more resistant to corrosion!
Fiberglass storage tanks can be used to store hypochlorous acid. For resistance to hypochlorous acid corrosion, vinyl ester resins are preferable.
It is recommended to use the polyurea type; we are using it very well
It is recommended to use vinyl resin, such as 901 resin.
It would be better to discuss the corrosion mechanism.
Our company used fiberglass before, and the results were very poor! The resin has oxidized! It became obsolete in less than two years, and its price wasn’t cheap either. If titanium lining is used, the cost is way too high! Our company is currently using PE storage tanks (of the one-piece type), and they work well. The two 18-cubic-meter tanks have been in use for 10 years now and are still functional; based on the current situation, it’s likely they can be used for another 5 years without any problems. The cost isn’t high either – around 1,300 to 1,500 per cubic meter per month. The only drawback of these tanks is that the welds at the joints where valves are installed are prone to leakage; however, as long as the valves are properly secured, there’s no issue
