Is there any quick method to prevent phosphoric acid corrosion of aluminum alloys?
Thread Content
RT! During the tests, a phosphoric acid immersion test is required, with a phosphoric acid concentration of 3.5% and a test temperature of 38°C. It is necessary to prevent corrosion of the aluminum alloy by phosphoric acid; therefore, there is an urgent need for a rapid protection method. If anyone has relevant information, please share it~
Polymer coating； That’s enough.
Can this coating be sprayed quickly? Similar to those spray cans

If so, it is recommended that you use hexamethylenetetramine (commonly known as Urotropin); the amount to use depends on the level of corrosion you desire! I hope this suggestion is helpful to you!
