Corrosion protection
Chromate-free sealed surface conversion system, nsd tupH, ensures easy yet safe cleaning, durability and wear resistance. This treatment permanently alters the physical properties of aluminum housing to create a surface that is up to seven times harder than the original. A clear sealant is then applied on top of the base layer to form a smooth surface that is easy to clean and maintain, while providing additional protection against acids and alkalis that will not spread corrosion, even if damaged, providing a more durable corrosion resistance.
