2 ... 5 years;
The protection lifetime depends on various parameters, such as: substrate pretreatment,
type and application of the coating system, loading, ...
The protection lifetime is no “warranty period”. The protection lifetime is a technical term that
can help the customer to specify a maintenance program.
EN ISO 12944-5, item 5.5 must always be consulted for all questions concerning the protection
lifetime.
