Difference Between PE & PVDF Coated Aluminum Sheet

Many friends found that the price of PVDF coated aluminum sheet is different from that of PE coated aluminum sheet. From the product names, we know that they are all color-coated aluminum sheets, and the two types of coated aluminum are the most commonly used in the market.

In fact, PVDF fluorocarbon coated aluminum sheets and PE polyester coated aluminum sheets differ in specifications, uses and coating raw materials. It can be seen that PE polyester and PVDDF fluorocarbon should be two kinds of chemicals, and polyester and fluorocarbon are indeed the coating materials used for the surface coating of aluminum plate. The surface of high-quality PVDF color-coated aluminum plate should have strong metallic luster, bright color and strong three-dimensional effect.

PE polyester coated aluminum sheet is used for interior wall decoration, with a warranty of 5-10 years without discoloration, and the conventional thickness is 1.5-2.5mm. PVDF fluorocarbon coated aluminum sheet is used for outdoor roofing and exterior wall decoration, with a thickness of 2.5mm -4mm. An easier way to tell them apart is to see if it's applied to interior or exterior decor. The surface of the coated aluminum plate is required to be uniform, smooth, without obvious defects such as missing coating, shrinkage holes, scratches, and peeling.

The PE coating formed on the surface of the aluminum plate by multiple baking has protective and decorative properties for the aluminum plate. PE coating is an anti-ultraviolet UV coating. UV absorbers can be divided into matt and high-gloss series according to the gloss. PE paint can not only impart rich colors to color-coated aluminum products, but also have good gloss and smoothness, and at the same time, it has superior texture and feel, and can also increase the sense of layering and three-dimensionality. PE paint protects atmospherically exposed objects from UV radiation, wind, rain, frost, snow and freezing. Due to the effects of temperature, freeze-thaw cycles, corrosive gases and microorganisms, PE coatings can protect objects. PE paint is especially suitable for interior decoration and billboards. The PE coating is formed on the surface of the PPAL sheet by multiple baking. It has good protective and decorative properties for PPAL sheet. PE coating is an anti-ultraviolet coating. UV absorbers can be divided into matt series and high-gloss series according to the gloss.

Due to the effects of temperature, freeze-thaw cycles, corrosive gases and microorganisms, PE coatings can protect objects. PE paint is especially suitable for interior decoration and billboards.

Fluorocarbon coatings are PVDF resin coatings. The chemical structure of fluorine acid bases is constrained by fluorine-carbon bonds. The stability of the chemical structure makes the physical properties of PVDF coatings different from general coatings. In addition to excellent mechanical properties such as wear resistance and impact resistance, PVDF coating also exhibits long-term anti-fading and anti-ultraviolet properties, especially in harsh environments. After baking the film at high temperature, the molecular structure in the coating is tight and has excellent weather resistance. PVDF is a fluorocarbon coating resin coating. The chemical structure of fluorine acid-base is bounded by a fluorine-carbon bond. The chemical structural stability makes the physical properties of PVDF coatings different from general coatings.

PVDF coatings are mainly used for the coating and decoration of PPAL indoors and outdoors in buildings.
