Sealing

Sealing is a chemical treatment applied after electroplating processes such as zinc or zinc-nickel plating, with the aim of further enhancing the protective performance of the coating.

The process involves applying a sealing layer that acts on the treated surfaces, reducing the permeability of the coating and increasing resistance to external agents.

The main advantages are:

• increased corrosion resistance
• improved long-term protection
• enhanced performance of the base treatment

Sealing is therefore a complementary treatment, particularly suitable for components exposed to aggressive environments or critical operating conditions.
