| Scenario/Conditions | Estimated service life | Key influencing factors |
|
Ideal environment
(For ordinary roofs and walls, standardized construction)
|
10-20 years | High quality tape, clean and dry base surface, correct pasting technique. |
|
Harsh environment
(such as high salt spray along the coast, extreme temperature differences, and strong ultraviolet radiation)
|
3-8 years | Salt spray corrosion, repeated freeze-thaw cycles, and accelerated aging by ultraviolet radiation. |
|
Improper use
(such as uncleaned base surface, low-temperature construction, and exposure to chemicals)
|
Less than 2 years, or even months | Oil/dust can cause weak adhesion, insufficient low-temperature bonding, and chemical corrosion. |
