Middle Eastern construction sites struggle with salt-induced aluminum corrosion, especially in coastal cities like Doha and Jeddah. Guangdayuan's VCI-infused PE film extends storage life by 6 months in harsh environments.
The white layer's vapor corrosion inhibitors form a molecular barrier, reducing oxidation from 22% to 1.3% on 6063 alloy after 2 months. Black layer's 99% UV blocking prevents photochemical reactions. Salt spray testing (96 hours) showed zero rust formation, outperforming conventional films by 300%.
Adhesion control (45g initial/65g final) prevents lifting during storage while allowing clean removal. A Dubai curtain wall company cut pre-installation cleaning time by 50% after switching to the film. 0.12mm and 0.18mm options accommodate different profile sizes, with air-release channels preventing bubbles during application.#PE black and white protective film#
