Request a quote Once you have determined the corrosivity of your environment, you can identify the right coating systems for your project and the right anti corrosion coating specification to protect it for years to
Corrosion, by definition, is a slow process, requiring days or years to occur to a noticeable extent, as opposed to similar electrochemical reactions such as etching, brightening, or anodizing which occur in minutes or less. Aluminum alloys may corrode via several different pathways. Recognizing the pathway or the forms of aluminum corrosion is

If aluminium is exposed to very strong acid or alkaline environments outside the pH range 4 to 9, violent corrosion will occur in the form of metal pitting. Bases break down the aluminium faster than acids - for example concentrated caustic soda reacts so violently with aluminium that it can start to boil. The reaction is powerful and causes
