In order to meet different application environments,
aluminum sheet coil needs different coatings like PE, PVC,PVDF, Polycraft and Polysurlyn. What are the differences and functions of these coating? Let’s come to know one by one.Polyester CoatingThe polyester coating on the
aluminum sheet coil can form a solid solid film with protective and decorative properties after several baking. Polyester coated
aluminium sheet is very suitable for interior decoration and advertising boards.It is a UV-resistant coating, which can protect the object from being exposed to the atmosphere, the attack of ultraviolet rays, wind, rain, frost and snow and the corrosion of temperature difference, freeze-thaw cycle, corrosive gas and microorganisms.PVC CoatingPVC trim coil offers homeowners the ability to keep the natural wood trim look they love. Many homeowners prefer PVC-coated aluminum wrapped trim for this reason.PVC-coated aluminum wrap can withstand high temperatures and extreme weather conditions. Rich colors and textures and low maintenance makes it popular in home decoration.PVDF CoatingAfter the PVDF coating is baked at high temperature, the molecular structure in the coating is compact and has super weather resistance. In addition to strong abrasion resistance and impact resistance in mechanical properties, it shows long-term fade resistance and UV resistance in harsh climates and environments.Polycraft Moisture BarrierPolycraft coating has two kinds: PolySurlyn coating and kraft paper coating. Aluminum sheet with polycraft moisture barrier and
aluminum coil with kraft paper are mainly used for anti-corrosion and thermal insulation projects, especially for pipeline insulation projects in Middle East oil countries.
