Comparing "Precoat" and "Polyural"! Detailed explanation to follow.
Salt-resistant and heavy salt-resistant outdoor units use aluminum fins coated with a polymer known as pre-coat, which protects the aluminum from salt damage and other hazards. However, while the thickness of the Polyual membrane is 20 to 25 micrometers, the pre-coat is only about 2 to 3 micrometers thick. After 3 to 5 years of exposure to salt damage, rust can occur, and the pre-coat membrane may disappear due to ultraviolet rays. Additionally, since the pre-coat involves processing aluminum sheets coated with polymer, the cut surfaces, internal cutouts, and contact points with copper pipes are exposed to the outside air, becoming entry points for salt damage and corrosion. The aluminum fin deterioration prevention coating "Polyual" addresses these issues. [Overview] The Polyual coating membrane is applied after the heat exchanger assembly, ensuring thorough protection of both the contact points with the copper pipes at the fin tips and the internal cutout areas. In salt-resistant pre-coats, these areas are exposed to outside air. *For more details, please refer to the PDF document or feel free to contact us.
