Aluminum is known for its robust corrosion resistance, which is why it is the material of choice in many exterior and architectural applications. Getting the highest performance out of the painted aluminum substrate is where the chemistry comes in. Paired with the proper cleaners and deoxidizers, these pretreatments will give your system the ability to function at highest level.
Traditional pretreatments for aluminum are chrome based. While the industry sands may be shifting to transition metal coatings, the chromate conversions still have their place in the industry. Robust and uniform, these coatings allow users to get the highest level of corrosion resistance in architectural, exterior furniture, marine, military, and other demanding applications.
Zirconium and other transition metals, coupled with organic additives, give the newest generation of aluminum pretreatments the ability to produce corrosion resistance at the highest levels. This allows users to minimize health, safety, and waste treatment impact on their facilities without reducing performance.
